Dry Scrubber Market Will Grow to $5 billion/yr

Dry scrubbers are taking market share away from the wet scrubbing alternative in coal-fired power, biomass combustion, cement, steel, waste to energy and other applications involving hot acid gases and particulate

The advantages of dry scrubbers are the reduced need for water, the elimination of wastewater, and the capture of mercury, dioxins, and sulfuric acid mist. The negative aspect is the elimination of valuable by-products. If the acid gas ratio in the fuel is low dry scrubbing has the lowest total cost of ownership. The higher the acid content the less competitive dry scrubbing is to wet.

Dry scrubbing is the preferred choice in glass plants, waste to energy, and cement plants. In some other applications it has half the market share. In coal fired power generation it has less than a 6 percent share. A major change is taking place in India where coal fired power plants are expected to use dry scrubbing for one third of the requirements. As a result, India will be a leading purchaser of dry scrubber hardware, lime and services in the future. It will spend just under $3 billion for dry scrubber hardware and construction over the seven-year period ending in 2025. It will be spending $650 million/yr for lime for dry scrubbing by 2025 and $325 million for service, repair and remote operation and maintenance.

Why Can India Justify Coal-fired Power Plant Expansion?

India is expanding coal-fired power capacity and can justify it based on the Sustainability Universal Rating System.

India expects coal-fired power capacity to grow by 22 percent in three years. That’s according to the Chief Engineer at the country’s Federal Power Ministry, Ghanshyam Prasad, who Reuters reported as stating coal capacity is likely to reach 238 GW by 2022.

India’s Coal Minister, Pralhad Joshi previously said annual coal demand rose by 9.1 percent during the year ending March 2019, noting the figure hit 991.35 million tons, driven primarily by utilities, which accounted for three-quarters of total demand. The anticipated growth is likely to affect efforts to cut emissions and could risk worsening already poor air quality. India’s electricity demand rose by 36 percent in the seven years up to April 2019, while coal-fired generation capacity during the period rose by three-quarters to 194.44GW.

Pralhad Joshi said, despite the growth rate in thermal capacity outpacing electricity consumption in the last few years, more coal-fired power plants will still be needed in the future to meet growth. He added: “If we have to meet demand and address the intermittencies we have with solar and wind, we have no choice but to keep depending on coal-based generation in the near future.”

India must address the question of balancing the benefits to the world vs. the benefits to citizens of India. Cardinal Health contracted with McIlvaine to answer a similar question relative to single-use surgical garments. Should a hospital throw away surgical garments after each use or wash them? Washing exposes local hospital clients to the risks of viruses in the water while manufacturing the garments generates CO2 somewhere. One risk is personal and immediate. The other risk is long term and general.

McIlvaine realized that it was necessary to develop a common metric to measure harm and good. This metric is labeled Quality Enhanced Life Days (QELD). It is described in a hospital magazine article. https://www.healthcaredevelopmentmagazine.com/.../quality-enhanced-life-days-a-ne...  In terms of decision making, QELD is radically different from the accepted medical metric Quality Adjusted Life Years (QALY).

Let’s say an Indian without electricity sleeps more hours at night. Without a large income he eats more fruit and vegetables and less ice cream and pizza. The Indian without electricity lives to age 90 while the Indian with electricity only lives to age 88. The QELD metric would rate the electricity option as superior while the QALY metric rates the “no electricity” scenario as superior. It is only common sense. Would you rather be in solitary confinement for the next 50 years or only live 40 years longer leading your present life?

The quality of life must be taken into account in any government policy. If coal-fired power can give reliable electricity to millions 10 years earlier than a plan that excludes coal, then the quality of life benefits has to be taken into consideration. Discounted future value has to be considered. The millionaire in the U.S. setting up a trust fund for his grandchildren enhances his life quality with this sacrifice. The Indian grandfather worried about the basic needs of his grandchildren will take satisfaction from making life better for them now. Since many of the negative impacts of greenhouse gases are long term, there is the necessity to realize that the discounted future value is dependent on the personal QELD of the individual.

It would be possible for the Indian government to estimate the cumulative QELD for all Indians for any policy and then choose the one with the greatest aggregate QELD. Bob McIlvaine welcomes your thoughts on this metric. You can reach him at 847-784-0013, cell 847-226-2391 or rmcilvaine@mcilvainecompany.com.

Determining True Cost for Dry Scrubbing Through Coal Fired Power Plant Decisions

Dry scrubbing is one of the options used by coal fired power plant operators to capture SO2, sulfuric acid mist and other acid gases. 44I Coal Fired Power Plant Decisions provides a forum for end users and suppliers to determine which pollution control options are best for a specific plant. Because of lack of water, low SO2 concentrations, weak gypsum market demand, and other factors a dry rather than wet scrubbing solution may be the best choice.

The choice is made more complex by the need to address multiple pollutants. Dry scrubbing is effective in removing SO3 whereas this is not true of wet scrubbers. With the addition of activated carbon, dry scrubbers can also remove mercury. There are multiple dry scrubber designs. Some are better with higher sulfur levels. So, the fuel becomes one variable in the pursuit of the lowest total cost of ownership solution.

There are multiple dry scrubbing technologies. One is the spray dryer absorber (SDA). This utilizes the same principle used in manufacturing instant coffee or powdered soft drinks. A slurry is sprayed into a vessel through which the hot gas flows. The liquid evaporates. The acid gas reacts with the absorbing particles. The particles are then captured in a fabric filter.

The circulating fluid bed (CFB) scrubber functions by passing the acid gas through a fluidized bed of lime particles. Circulating Dry Scrubbers (CDS) entrain and then separate the particles. Lime or sodium particles are injected into the flue gas duct with Dry Sorbent Injection (DSI) systems. The catalytic filter uses the DSI principle ahead of a ceramic filter medium with embedded catalyst for both particulate control and NOx reduction.

There are a number of materials, fibers, media configurations and element designs which are utilized. The collection media in the fabric filter has a major impact on cost. The optimum gas velocity can vary depending on the media selected. If the velocity can be doubled then the size of the unit can be halved. Instead of 4000 bags for a big installation maybe only 2000 would be needed.

On the other hand, the cost of ownership is significantly affected by the bag life. If bags last one year rather than four or five years, then bag costs become a significant part of the total expense. The energy cost is also a factor. Energy consumption increases in direct proportion to velocity. It also increases in direct proportion to the thickness of the dust cake on the filter media.

In the case where only particulate is to be captured it is best to establish a semi-permanent cake on the bags and then pulse off the new cake. In accounting terms this is last in first out (LIFO). However, for dry scrubbing it is best to remove the reacted gypsum and retain the fresh lime (FIFO). The industry has not formally addressed FIFO versus LIFO and needs to do so.

The need to maximize acid gas capture and the resultant substantial increase in particulate loading affects the choice of fibers and filter media. The type of cleaning (reverse air or pulsing with compressed air) also determines the selection of the lowest true cost medium.

The fuel or product being calcined or treated also impacts the medium. If a high sulfur fuel is burned, the costs of dry scrubbing are comparatively higher than if a low sulfur fuel is burned. Various fibers react differently to various combinations of acid gases, temperature and humidity. One fiber may handle SO2 and HF in relatively humid conditions at 300° F whereas another cannot.

Temperature resistance is important for several reasons. One is that a fiber which can withstand the temperature excursions will have a longer life than one which is dependent on more perfect operation of the system. Another consideration is the potential to recover heat.

An alternative to glass and polymeric resins is a ceramic fiber matrix. Elements can contain embedded catalysts. Dry sorbent injection ahead of the ceramic media can be utilized to provide removal of dust and acid gases while reducing NOx. The resultant clean hot gas at 600° F or higher can then be directed to an efficient heat exchanger and most of the potential energy recovered.

The material, fiber design, media construction and filter element shape all have to be designed to address the unique requirements of the application and the technology being employed.

The two major fiber types are glass and polymers.

There are differences in laminates with multiple non-woven layers being employed with varying support materials and designs. Fiber shape is also a variable.

How complex are the decisions: There are at least 1500 combinations to assess.

But there are also site-specific considerations such as cost of electricity, reagents, pollution limits, plant life, existing equipment. So, these can present another 100 variables resulting in 150,000 factors.

There are mountains of information available on all the different variables. Determining which information will help select the lowest total cost of ownership product is a daunting task. The answer is “shared responsibility and collaboration”. Organizations focused on components such as filter media or reagents can contribute but only if there is a clear path on how to do so. The Dry Scrubber Users Group which is focused on the subject in the broadest terms can be the catalyst to help bring other organizations into what can be titled a True Cost program. The program can provide access to the needed evidence for validation of lowest total cost of ownership. Conferences and exhibitions can provide a forum for actual validation of supplier claims. The categories include component related conferences as well as industry conferences.

Shared responsibility and collaboration are best driven by suppliers who are convinced that their product has the lowest true cost and are willing to help provide all the evidence pro & con to support their position. Coal Fired Boiler Decisions has a Dry Scrubber Decision Guide, a monthly FGD newsletter and another newsletter just on Fabric Filters. Information has been compiled for this service for 45 years. Collaboration with publishers and conference organizers includes dry scrubbing tour maps and networking at exhibitions. 

Coal-Fired Power Plant Decisions is being offered free of charge to utility operators. Suppliers are able to participate with just a $1600/yr subscription. For more information click on 44I Coal Fired Power Plant Decisions.

COAL-FIRED BOILERS

How ACE Affects Today’s Utility Plants

The Affordable Clean Energy (ACE) Rule, which was finalized June 19, replaces the Obama Administration’s Clean Power Plan (CPP). ACE is similar to what was originally proposed as Building Block 1: a list of “energy efficiency measures” that power plants will need to install; each unit will be prescribed its control measures individually by its state. “States will evaluate applicability to their existing sources of the six candidate technologies and improved operating and maintenance practices and take into consideration source-specific factors in establishing a standard of performance at the unit level.”

The rule did not set specific limits. It demands the State determine the limits. The rule only applies to certain existing coal-fired Electric Generating Units (EGUs) and excludes integrated gasification combined-cycle (IGCC) facilities.

ACE applies to plants which:

·         Were operating or in construction before January 8, 2014,

·         That sell greater than 25 megawatts (MW) to the grid

·         Have a base load rating greater than 250 MMBtu/hr, and

·         Burn greater than 10-percent coal as part of the plant’s average annual heat input

ACE excludes:

·         Simple cycle combustion turbines

·         Combined cycle combustion turbines

·         Combined heat and power combustion turbines

·         IGCC

Heat Rate Improvement is the best system of emission reduction, but at least eight technologies must be evaluated by the states. Each of these eight technologies must be evaluated for what improvement (limit) they could achieve. Then each technology is accepted or rejected based on cost, feasibility, other reasons that are supported in the evaluation. However, similar to a Best Available Control Technology (BACT) analysis under PSD, the rule did not define what is “too costly.”

(1)      Neural network

(2)       Intelligent sootblowers

(3)       Boiler feed pumps

(4)       Air heater and duct leakage control

(5)       Variable frequency drives

(6)       Blade path upgrade (applicable to a steam turbine)

(7)       Redesign or replace the economizer

(8)       Improved O&M practices, such as operator heat rate improvement training, on site appraisals, and condenser cleaning

States must set an emission rate and it is anticipated this rate will be in terms of net or gross pounds of greenhouse gas per megawatt (lb./MW). The state must specify how these limits will be verified (continuous emissions monitors, annual stack test, etc.). States have flexibility in setting these limits, which can be set at various averaging periods or different rates can be set for different loads. Where rates not readily verified or measured, operating practices could be the solution. States can consider source specific factors like remaining useful life of an existing source in applying performance standards to that source, which gives a state the ability to exempt an older unit from compliance or setting a less stringent standard for older assets. Averaging across designated facilities at a single plant and averaging/trading between plants is NOT permissible.

Technologies that do not have to be reviewed include:

·         Natural gas repowering

·         Natural gas co-firing

·         Natural gas refueling

·         Carbon capture and storage

·         Co-firing with biomass is not allowed to be reviewed

·         Carbon capture and storage, full or partial

States have three years to evaluate all the units and submit a State Implementation Plan (SIP) to the EPA. The EPA has six months to determine if the SIP is complete or not. he EPA will act on the SIP within 12 months after determination if it is complete or 18 months after it is submitted if no completeness determination is made. The EPA has two years to issue a Federal Implementation Plan (FIP) after SIP is incomplete or disapproved, or failure of State to issue a SIP.

Finally, and importantly, the EPA has not finalized anything regarding proposed changes to New Source Review (NSR) for “energy efficiency projects,” which can easily trip Prevention of Significant Deterioration (PSD) permitting and installation of Best Available Control Technology (BACT) for non-greenhouse gas pollutants. The EPA intends to take final action on the proposed NSR reforms in a separate final action at a “later date.” Until then, EPA advises consult with your legal staff for evaluation the PSD implications of implementing the ACE rule.

Coalition of U.S. States and Cities Challenges Trump Coal Pollution Wind-back

A coalition of 22 states, the District of Columbia and six cities have filed a legal challenge in the U.S. Court of Appeals against the Environmental Protection Agency’s (EPA) regulation to replace President Obama’s Clean Power Plan. The Clean Power Plan set state-by-state targets for greenhouse gas emission reductions from coal-fired power plants while the latest EPA plan leaves emissions cuts up to each state. The legal challenge argues that the EPA’s replacement rule does not “meaningfully” cut greenhouse gas emissions and is not consistent with the Clean Air Act.

Doosan Lentjes to Supply Fabric Filters in the Czech Republic

Doosan Lentjes is pleased to announce that it has signed a contract for the supply of fabric filters for a power plant in Chvaletice, Czech Republic. The main contractor is the local company ZK Termochem.

The power plant with its 4 x 205 MWe boilers is owned and operated by the Czech energy supplier Seven Energy. All four units will be equipped with new filter systems, with the filters for boilers 3&4 being installed first, followed by those for boilers 1&2.

The current contract includes the delivery of two new low-pressure bag house filters downstream of boilers 3 & 4; the contract for the delivery of the filters for the units 1&2 will be concluded separately.

Doosan Lentjes’ scope of work in the project will include engineering, delivery of key filter internals and the flyash transport system.

WASTE -TO-ENERGY

36,000 Hours of Operation for P84+PPS Bags at Eskom

Eskom owns and operates more than 40 GW of installed capacity and is the largest utility in Africa. The Arnot Power Station consists of six nominally rated 350-MW coal-fired units originally installed between 1968 and 1975. The station burns a relatively poor South African bituminous coal composed of 25 percent ash with a heating value of 26 to 27 megajoules per kilogram (MJ/kg). The plant has posted 92.07 percent average availability over the past three years. 

Arnot Power Station was upgraded from ESPs to baghouses in the 1990s as part of a project to increase plant capacity. Phase 1 added baghouses to Boilers 4, 5 and 6 (each containing 11,000 bags) with a maximum gas-to-cloth ratio of 3.5 CFM/ft2. Phase 2 added baghouses (each with 14,000 bags) to the remaining three boilers with a maximum gas-to-cloth ration of 2.8 CFM/ft2.

Once Eskom understood that blinding was the predominant bag failure mechanism across the various plants, it embarked on research aimed at retarding the blinding rate, hence extending bag life and performance. After a number of trials, and in collaborative effort with fiber and fabric suppliers (including the full-scale evaluation at Arnot), the solution chosen was to install composite bags with a P84 cap applied to a PPS substrate, which ensured the formation of a porous and stable dust cake that promoted complete acid neutralization and surface filtration. The service life of the latest sets of P84+PPS bags is more than 36,000 hours, with less than 10 percent failure of the 27,000 bags installed per unit.

The switch to P84+PPS bags has resulted in significant savings for Eskom, about $500,000 annually. That figure does not include reduced costs for labor, or production losses, which can be significant. In one instance, prior to the switch to P84+PPS bags, two boilers were shuttered for four months waiting for replacement bags.

Valmet to Supply a Biomass Boiler and a Flue Gas Treatment Plant to BS Energy’s Combined Heat and Power Plant in Braunschweig, Germany 

Valmet will supply a biomass-fired boiler and a flue gas treatment plant to BS Energy's combined heat and power (CHP) plant in Braunschweig, Germany. The order was included in Valmet's orders received of the second quarter 2019. The total value of the order is around €50 million.

The boiler with its auxiliary equipment will be part of BS Energy’s energy production strategy 2030. The primary target of the investment is to replace the coal-fired boiler, which will be removed from production in 2022. In addition, the new biomass-fired CHP plant will support BS Energy's objective of environmentally friendly and carbon-neutral production, as it will serve as a base-load unit to meet the district heating and electric power needs of the Braunschweig municipality.

The biomass-fired CHP plant will produce approximately 20 megawatts of electricity and 60 megawatts thermal of district heat. The takeover of the biomass-fired CHP plant is scheduled for early 2022.

The CYMIC circulating fluidized bed boiler included in Valmet's delivery will use recycled wood as its primary fuels. The boiler generates 27 kg/s of high-pressure steam at a pressure of 75 bar and a temperature of 525°C. Its steam-generating capacity is 78 MWth.

The flue gas cleaning system included in the delivery will enable fulfilling the tightening emission standards for the future, with the help of a two-phase dust removal system and a semi-dry sorbent injection system.

MHIEC Receives Order to Refurbish the Hiroshima Naka Waste to Energy Plant

Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), has received an order from the Hiroshima city government to refurbish the combustion facilities at the Naka Waste to Energy Plant for a municipal solid waste (MSW) in Minamiyoshijima, Naka-ku, Hiroshima, with a total waste treatment capacity of 600 tonnes per day (tpd). MHIEC will refurbish and improve stoker type incinerators (1) and related equipment, extending the working life of the facility and enhancing its energy efficiency. The contract is valued at 5.84 billion. Completion is scheduled for in March 2023 (four-year project).

The Naka Waste to Energy Plant was designed and built by MHI and completed in February 2004. It has three stoker type incinerators, each with a capacity of 200 tpd that operate continuously 24-hours per day, and related equipment. The facility generates 15.2 MW of electricity to power the equipment in the factory, selling the remainder.

The renovation contract comprises the renewal of superannuated core components at the facility, including the receiving and feeding equipment, combustion facilities, exhaust gas cooling equipment, ventilation systems, ash extractors, and instrumentation. The renovation will incorporate MHIEC's patented New Incineration Control System to support stable incineration, as well as the use of high-efficiency motors and inverters to increase energy efficiency. These measures will reduce CO2 emissions by around 9.6 percent annually, helping to curb global warming. 

WELDING FUMES

Nederman Offers Solution to the Dangers of Welding Fumes

The Nederman website discusses the health risks of welding fume, and how to reduce them in the workshop.

Some of the components of welding fume, such as oxides of chromium, nickel, cadmium and manganese, are known or suspected carcinogens. As stainless-steel welding fume has a higher content of these alloying elements (as well as carbon) than mild steel welding fume does, the former was up until recently thought to be significantly more hazardous. What the IARC discovered is that while mild steel welding fume contains much lower concentrations of these elements, the concentrations are still potent enough to cause cancer in humans.

The fume created by welding processes is made up of solid particulates (ranging from 10 nanometers to 20 microns in size), which are formed when metallic vapors condense. Much of this fume is respirable and can penetrate deep into the lungs, where it can do significant harm and also spread into the bloodstream.

What further exacerbates the risk of exposure is that the act of welding requires the welder to locate his or her head – and, hence, breathing zone – close to the point of fume generation, as the welder simply needs to see the weld progressing. Unless there is adequate fume capture in place, the welder will be exposed to a high concentration of hazardous fumes.

While the proximity to the fume source (and its significant fume concentration) puts the welder at an especially high risk of exposure, fugitive emissions may affect other personnel as well. This a key reason why effective at source capture is the recommended engineering control method, as it prevents the fume from entering and spreading throughout the general atmosphere. It is also for this reason that general ventilation without at source capture, with the welder alone wearing respiratory protection (once a common method of fume control), is no longer recommended.

Nederman has developed an industry-leading portfolio of at source fume capture products which minimize the welder’s exposure to hazardous welding fume. They are able to offer efficient solutions for any welding application, whether it is high air volume, easy to position extraction arms or FilterCart. Fume Eliminator, and multi-user fixed weld fume extraction systems.

COMPANY NEWS

Donaldson Achieved Record Sales in 2019

Donaldson Company, Inc. reported 2019 net earnings of $58.0 million in 4th quarter and $267.2 million for the full year, compared with $102.4 million and $180.3 million, respectively, in 2018. Excluding certain one-time items in the current and prior years, adjusted earnings per share (EPS) were $0.61 in 4th quarter and $2.21 for the full-year 2019, an increase of 5.2 percent and 10.5 percent, respectively, from 2018.

“We generated record sales and profit in 2019, due in part to strong performance in our Advance and Accelerate businesses, and we made a record level of investments to drive long-term profitable growth,” said Tod Carpenter, Chairman, President and Chief Executive Officer. “We were pleased with sales results last quarter, which matched our forecast, and earnings were also in line as a better-than-expected tax rate offset the impact of demand volatility on gross margin.

“Our fiscal 2020 plan reflects focused portfolio management in an uneven demand environment. It is likely that uncertainty related to global trade and the political environment will keep our customers cautious, and some of our engine-related end markets are nearing the peak of their economic cycle. As these factors affect demand, our innovative products with recurring revenue, combined with disciplined expense planning, give us greater stability and flexibility as we remain focused on the future. We are making incremental investments to drive our strategic priorities in 2020, and we are aggressively pursuing gross margin improvement opportunities. Our company is aligned on our strategic and operational objectives, and we are excited about our path to delivering another year of record profit.”

The 4th quarter sales of Industrial Products (Industrial) increased 3.3 percent from last year. Industrial realized benefits of 3.9 percent from BOFA and 0.5 percent from pricing, partially offset by a negative impact from currency translation of 2.2 percent. Sales of Industrial Filtration Solutions (IFS) increased 6.2 percent, reflecting benefits from BOFA and replacement parts, partially offset by lower sales of new equipment. Gas Turbine Systems (GTS) sales increased due to the timing of new equipment sales, and the Special Applications (SA) sales decline was due to Disk Drive filters.

The 4th quarter 2019 operating income as a rate of sales (operating margin) declined to 14.4 percent from 14.9 percent in 2018,4 including a negative impact of 0.1 percentage point from revenue recognition.

The 4th quarter gross margin was 33.5 percent, compared with 34.9 percent in 2018, including a negative impact of 0.2 percentage points from revenue recognition. The year-over-year gross margin decline was driven by unfavorable mix of product sales within markets, combined with higher raw materials and supply chain costs. These gross margin pressures were partially offset by pricing benefits. Operating expense as a percent of sales (expense rate) improved 0.8 percentage points to 19.2 percent from 20.0 percent in 2018, reflecting lower incentive compensation expense, partially offset by higher salary and other employee-related expenses.

Donaldson expects fiscal 2020 GAAP EPS between $2.21 and $2.37, compared with fiscal 2019 GAAP and adjusted EPS of $2.05 and $2.21, respectively.

Compared with 2019, fiscal 2020 sales are projected in a range between a 2 percent decline and a 4 percent increase, including a negative impact from currency translation of 1 to 2 percent that is partially offset by price benefits of approximately 1 percent. Industrial sales are expected to increase from fiscal 2019 between 2 and 8 percent, reflecting growth in IFS and GTS, partially offset by declining sales in SA. Within Industrial, growth in IFS is due in part to one quarter of incremental benefits from the acquisition of BOFA. Currency translation is expected to negatively impact both segments by 1 to 2 percent.

All Babcock & Wilcox Business Segments Showed Improved Results

Babcock & Wilcox Enterprises, Inc. ("B&W Enterprises") announced 2nd quarter 2019 GAAP net loss from continuing operations improved by $181.3 million to $28.3 million compared to $209.7 million in 2nd quarter 2018. Adjusted EBITDA also improved by $90.4 million to a positive $8.0 million compared to negative $82.4 million in the prior year period, returning the company to profitability on an adjusted EBITDA basis.

"Our performance in the 2nd quarter of 2019 shows we are continuing to gain steam following our recent strategic actions and cost-saving efforts. Our consolidated business improved operating margins significantly and returned to profitability on an adjusted EBITDA basis of $8.0 million. Our Babcock & Wilcox segment continued its strong performance and across the company we are making steady progress on our strategy to improve profitability by focusing on our core technologies and businesses," said Kenneth Young, B&W Enterprises Chief Executive Officer.

"We expect to see improvement each quarter as our cost-savings measures continue to translate to bottom-line results and the effects of the EPC loss contracts continue to decline.

Gross profit in the Babcock & Wilcox segment in 2nd quarter 2019 was $37.9 million, compared to $30.0 million in the prior-year period, primarily due to higher construction volume and lower warranty costs. Gross profit margin was 18.8 percent, compared to 15.2 percent in the same period last year. Adjusted EBITDA in 2nd quarter 2019 increased 92 percent to $19.0 million, compared to $9.9 million in last year's quarter; adjusted EBITDA margin was 9.5 percent compared to 5.0 percent in the same period last year.
