Dry Scrubbing: Most Profitable Markets
The largest market for dry scrubbing is to capture SO2 from coal fired power plants. Wet scrubbing is used by 95 percent of the coal plant operators. The reason is the much lower reagent cost and the opportunity to generate a byproduct (gypsum). Dry scrubbing offers much lower capital cost as well as reduction in water consumption and pollution. In many cases the dry scrubbing option is eliminated by default. Limestone for wet scrubbing is widely available at a predictable cost. Reasonably priced lime for dry scrubbing may only be available if a lime supplier agrees to build a dedicated kiln just for a plant or several plants in a region. The catalytic filter with dry sorbent injection (DSI) is now proven in many smaller applications. The recent introduction of 6 meter long candles makes it a candidate for power plants as well as the smaller applications. One vessel instead of three is used to reduce NOx, SO2, other acid gases, and particulate. Furthermore clean hot gas at 600F is available for energy recovery.

GEA supplies glass plant catalytic filter
GEA Glashütte Freital contracted with GEA for supply and installation of a compact plant for the cleaning of flue gases resulting from melting furnaces. ( More recently GEA announced that 2 meter candles are now available for this technology) The Customer selected GEA’s BisCat technology (Bischoff Catalysator technology) thanks to low space requirement and combination of several process steps in one reactor. The new furnace has a melting capacity about of 150 t/d, commissioning along with GEA’s emission control plant was scheduled for March 2019. Generally the furnaces in the glass production are equipped with flue gas cleaning plants which have separate steps for treatment of particulate, acid crude gases and nitrogen oxides. GEA has developed a technology which reduces these steps to one single step in a single reactor. The flue gas cleaning process is carried out by means of rigid filter elements consisting of coated mineral fibers, so-called ceramic candle. These candles are well-proven and very flexible to use even with regard to modifications of operating parameters, especially at high gas temperatures. Even stricter future requirements set in the Federal Administration‘s Regulation “Technical Instructions on Air Quality Control (TA Luft)” will be underrun. Dust emissions are near to detection limit. GEA has already delivered plants of this kind for the purpose of hot gas filtration and has now refined these plants recently in order to include the separation of nitrogen oxides resulting from flue gases (DeNOx). The ceramic candles are installed in a walk-in clean gas chamber to ensure easy access for maintenance and inspection.

HZ-inova Xerosorp captures acid gases, removes NOX and recovers heat
This device includes sodium bicarbonate injection into a reactor, recovery in a fabric filter and reinjection of captured solids. The cleaned gas then passes into a catalyst system which is efficient at removing NOx at temperatures as low as 200C. This catalyst is regenerated by including multiple modules. One module is regenerated while another module is cleaned. Cited advantages are • Very compact design • Reaches lowest emissions • Lowest Bicar consumption due to residue circulation • Damping of peaks due to high residue buffer capacity in the recirculation system • High energy efficiency due to: – Low pressure drop – Low regeneration rate of catalyst in offline mode – Tail end heat recovery.

This study by Sargent & Lundy provides methods to determine costs of DSI for acid gas removal. The sorbent requirement is a function of particle size, particulate control device, and other factors. 2016 cost factors are utilized. Based on commercial testing, removal efficiencies with DSI are limited by the particulate capture device employed. Trona, when captured in an ESP, typically removes 40 to 50% of SO2 without an increase in particulate emissions, whereas hydrated lime may remove an even lower percentage of SO2. A baghouse used with sodium-based sorbents generally achieves a higher SO2 removal efficiency (70 to 90%) than that of an ESP. DSI technology, however, should not be applied to fuels with sulfur content greater than 2 lb SO2/MMBtu.

Dynegy SDA installation at Baldwin is permitted for new wastewater discharges
The subject facility has applied for a renewed NPDES permit which includes modifications that necessitate an antidegradation assessment. New wastewater discharges will be created as the result of the construction and operation of new dry flue gas desulfurization systems (Spray Dryer Absorbers or SDAs) at all three units at the complex. The installation of these systems was required by the terms and conditions of a 2005 Consent Decree between Dynegy, the state of Illinois, USEPA, and the U.S. Department of Justice. Construction of the Unit 3 SDA system and baghouse has been completed and they were put into service prior to December 31, 2010. The Unit 1 SDA system and baghouse were placed into service by December 31, 2011. The Unit 2 SDA system and baghouse were placed into service by December 31, 2012. The new discharges from these systems would consist of sump discharges, air compressor noncontact cooling waters, and miscellaneous floor and storm drainage waters. Dynegy is requesting authorization to discharge these wastewaters to the existing bottom ash pond system and include these discharges as contributory wastewater streams to Outfall 001. Sump discharges are not expected to occur more than once per week with each discharge lasting approximately five minutes. Based on the current operation of the Unit 3 sumps (projected discharge of 0.127 MG/year), it is expected that sump discharges for all units would contribute 0.38 MG/year of flow to the ash pond. Air compressor noncontact cooling waters from the new SDA systems (6.5 MGD) and miscellaneous floor and storm drainage waters would be received by the cooling pond and would be potentially discharged from Outfall 002 during overflow conditions

Scrubber Market Veering From Hardware to Consumables
Dry scrubber capital investment will be just under $600 million in 2015. This is less than 10 percent of the total scrubber capital investment. But behind these numbers is a new path for the industry. Dry scrubbing is a way to capture acid gases at lower capital cost than with absorbers. However, purchasers face much higher reagent costs. Limestone used in wet systems is a fraction of the $200/ton price of lime used in dry scrubbers. These developments are tracked in the McIlvaine publication Scrubber/Adsorber/Biofilter World Markets.

Need to balance air flow among modules in dry scrubber system
A number of the dry scrubber and SDA designs require modular supply due to size limitations. This introduces the need to measure the gas flow to each module. The strength of the Promecon gas flow measurement system is hot dusty applications. So the technology is well suited for measuring the flue gas flow to individual scrubber modules. The sensors are solid rods and the technology utilizes the fly ash particles.

More Dry scrubber analysis from Kiewit
See previous articlesfor details but here is more: For the CFBs, a typical approach temperature is 30°F to 40°F, while for the NID a tighter approach of 25°F to 30°F is more common. Because the temperature is still maintained above saturation, reactor materials of construction are typically carbon steel. Type 316 L stainless steel is often used for specialty components such as water injection nozzles and some lime hydrator parts.

Extensive CDS Experience Already Gained in U.S
Lime and hydrated lime are widely available to meet the demands of FGT applications in the U.S. power industry. Lime-based CDS technologies have become popular options to achieve very high removals of multiple pollutants produced from solid fossil fuel-fired electricity generating units. Four lime-based CDS technologies have been installed in 12 PC boilers and 12 CFB boilers. Constructions are underway at 15 PC boilers. These technologies are applied to units with sizes ranging from 58 to 690 MW. Data obtained from AES Greenidge and Sandow Stations showed that the emission limits of Hg, filterable particulate, and HCl mandated under the Mercury and Air Toxics Standards were met. CDS is capable of handling solid fuels with various sulfur contents. CDS is capable of handling wide swing load. Multiple CDS reactor vessels can be placed in parallel to process flue gases from larger units.

Spray Dryer FGD at TEP Springerville
The dry FGD system for each unit comprises three spray dryer absorbers (SDA) with rotary atomizers and a reverse-air fabric filter. The Springerville Station receives high-calcium pebble lime via rail, and a pneumatic system transports the lime to a day bin located at each unit. Horizontal ball mill slakers convert the pebble lime to lime slurry, which is combined with a slurry of recycled material from the fabric filter just prior to being fed to the rotary atomizer. When the units were constructed, the dry FGD systems were built with a partial bypass, the result of which is that 75% of the flue gas is treated in the spray dryers and the bypassed flue gas is recombined with the scrubbed stream before entering the fabric filter. TEP, with S&L as Owner’s Engineer, implemented the following modifications to reduce NOX and SO2 emissions: • Installation of low-NOX burners and overfire air (NOX). • Installation of a fourth spray dryer and elimination of the flue gas bypass (SO2).

Gas Suspension Absorber / Description
One of the reasons for the high efficiency of the KC Cottrell GSA is that the reactor has been based on gas suspension technology. This means that a very large concentration of fly ash, dust particles and lime builds up inside the reactor. The concentration is normally 50 to 100 times as high as in a conventional reactor. The effect is further enhanced by the fact that lime, fly ash and by-products are recycled about 100 times in the KC Cottrell GSA system. A short erection period is achieved due to a modular design, offering enormous flexibility. Maintenance costs for the KC Cottrell GSA are extremely low compared to more conventional plants. One reason for this is the minimal wear and tear due to few moving parts and a very simple, uncomplicated and stationary nozzle.

Features and Benefits of KC Cottrell’s Gas Suspension Absorber (GSA) Technology
The lime can be injected either as a slurry, through commercially available two-fluid nozzle atomizers, or as powdered calcium hydroxide. The intense recirculation within the reactor promotes efficient acid gas neutralization, resulting in high removal efficiencies at low lime consumption rates. The nozzles are commercially available and can be changed out on the fly, without impacting scrubbing efficiency. The use of the cyclone to capture and recycle solids from the reactor vessel greatly reduces the demand on the downstream particulate collector. The slim profile of the GSA reactor vessel itself minimizes plan area requirements, which are frequently at a premium in retrofit applications

New FGD & DeNOx Approaches - Webinar April 7, 2011
Discussion on the current "state of the art" for FGD and DeNOx systems, the capabilities and limitations of current control systems and technology, the latest advancements in control technology being developed or tested and what still needs to be done to allow the utility industry to comply with the coming MACT and the other regulations.

Shiaw Tseng, Marketing Manager at Graymont, Inc., described a multi-pollutant control system for existing coal-fired power plants using lime-based Circulating Dry Scrubbers (CDS) to remove SO2, SO3, HCl, and HF. He presented the results of performance guarantee tests conducted at the AES Greenidge Station Unit #4 (107 MW) burning eastern bituminous coal (2.5 to 3 percent sulfur) with a CDS and baghouse. These tests showed pretty impressive reductions of SO2, SO3, Hg and HCl to levels that were well under the limits in the proposed utility MACT. Advantages of this system include a relatively small footprint, fuel flexibility (including biomass), low water consumption and dry byproducts (no wet sludge). Interestingly, the CDS system achieved better mercury reduction than using ACI under the same operating conditions, indicating that ACI is not required. These systems are currently operating at 14 plants in the U.S.

Improving ESP Performance Webinar - Hot Topic Hour January 20, 2010
ESP Performance Improvement can be Substantial - Hot Topic Conclusion on January 20 There has been lots of focus on replacing ESPs with baghouses to meet upcoming regulations. The speakers in the Hot Topic Hour yesterday said there is an alternative. You can upgrade existing ESPs and achieve results which may satisfy future requirements. Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., told the attendees that “there is a better alternative to SO3 for conditioning electrostatic precipitators.” Trona addition system is simple and its capital cost is much lower than that of a SO3 production and injection system. Trona is relatively inexpensive and can be injected in several places. Mick Chambers, Southern Environmental, Inc, said that you can upgrade your ESP and with halogen-based additives in the coal, you can meet the particulate and mercury regulations. He showed that the SCA of recent installations has been relatively low and yet the performance high. So the footprint of a retrofit does not have to be large. When asked about the wet ESP using a fabric for the collection plate, Mick said that it is a good option and successful on industrial boilers and process applications. We were sorry to learn that John Caine passed away in a tractor accident last September. John had represented SEI in several of our previous Hot Topic Hours and has long been a contributor to the industry. Steve Jaasund, Manager Geoenergy Division A. H. Lundberg Associates, made a case for adding a wet ESP after the FGD system to meet the upcoming MACT regulations. In the discussion period it was speculated that the new mass monitoring requirements would make it more difficult for dry ESPs to meet emission limits. The wet ESP will eliminate the exceedance spikes associated with a stand-alone dry ESP. Paul Leanza of Pollution Control Services, Inc. indicated that many utilities have the opportunity to greatly improve performance of their existing precipitators. He indicated that 50 percent of the emissions occur during rapping (rapping reentrainment). These particles are relatively large and do not cause opacity spikes proportional to the mass increase. It was speculated that with mass monitoring this phenomenon will be an unpleasant surprise. Emissions will be higher with mass monitors than they were thought to be with opacity monitors and periodic stack testing. Ron Landreth of Albemarle was pleased to find that their brominated PAC actually improves precipitator performance whereas the non-brominated PAC may add to emissions. So it is worth considering brominated PAC to capture mercury and reduce particulate. Jean Bustard of ADA-ES (ADA Environmental Solutions LLC) related experience with a proprietary conditioning chemical which has performed well and does not impact mercury capture with PAC. The company offers another approach to conditioning hot side precipitators.

David W. South, Manager of Business Development at Amerex, drew from a considerable bank of experience the company has gained with some 50 MACT related boiler installations in the last five years. One unit on a PC boiler with carbon injection and a fabric filter is using 2.2 lbs/MMacf of B-PAC. Inlet mercury is 20 lbs/TBtu versus 2.5 lbs/TBtu on the outlet. Another with only 2.0 lbs/MMacf is reducing mercury from 25 lbs/TBtu to less than 2 lbs/TBtu.
