Hot Gas Filter Market Has Potential to Grow By a Multiple Of 100

The market for filter elements which can withstand temperatures of 850oF has the potential to grow from just $30 million/yr now to over $3 billion/yr over the next decade.  This is the conclusion reached by the McIlvaine Company in World Fabric Filter and Element Market.  (www.mcilvainecompany.com)

Power, cement and waste-to-energy plants can benefit from a lower cost alternative for air pollution control while, at the same time, generating water rather than consuming it and greatly reducing energy consumption compared to alternatives. There are two options each with a different sorbent.  Each will meet the most stringent standards for fine particulate, mercury, NOx, SO2, HCl, and VOCs.

Calcium Sorbent Option




Fuel belt


Add halogen e.g. calcium bromide


1000oF +

Add fine powdered limestone and urea

Gas Turbine Intake Filters Is the “Hot Topic” for the Webinar May 15th at 10 a.m. CDT

This webinar will examine the advantages of investing more in order to obtain higher efficiency removal of particles.  Part of the discussion will evaluate claims in a white paper displayed on the site which shows that turbine maintenance is greatly reduced by higher efficiency filtration.  The owner can afford to more than double his investment in filters and still lower overall costs.

The panelists will pursue whether this conclusion is widely applicable or limited to certain inlet air quality conditions. It will also pursue the best options for achieving the required efficiency. The discussion will also include many aspects of the selection and use including:

·       Static filters or pulsed filters

·       Number of filtration stages

·       Filter fibers or resins (glass and synthetic)

·       Filter media (glass, synthetic, mix)

·       Filter shape (pleating, cartridge, etc)

·       Variations to cover unusual ambient conditions such as arctic and ocean platforms


·       Placement of and use of coalescers in conjunction with filters


·       Maintenance issues  such as replacement rate, ease of replacement, increased energy loss with time, and coating of turbine blades


·       Testing requirements


·       Air pollution control aspects (may need to remove PM2.5)


Panelists will include:

Dan Burch, Clarcor, Product Marketing Leader

Tim Nicholas

ITR Team Leader – Aftermarket & Services CLARCOR


Jim Lenox

Senior Product Manager, Inlet Filtration CLARCOR Industrial Air


Paul Barilla, Consultant


Hersh Chaturvedi, Eastman


Other supplier and consulting experts.


This discussion will be focused on data which has already been posted to a dedicated website.  Participants are asked to review this material prior to the meeting.  The website is

Renewable Energy Briefs

Mars Moves towards Carbon Neutral Operations with Massive Wind Farm

Mars, Incorporated, in partnership with Sumitomo Corporation of Americas, announced an agreement on a new 200 MW wind farm that will generate 100 percent of the electricity needs of Mars’ U.S. operations, which is comprised of 70 sites, including 37 factories and 25,000 Associates.

‘Mesquite Creek Wind,’ a 118-turbine wind farm was jointly developed by Sumitomo and BNB Renewable Energy and is based near Lamesa, TX with a footprint of 25,000 acres. With an annual output of over 800,000 megawatt-hours, the energy created from the wind farm will represent 24 percent of Mars’ total global factory and office carbon footprint – equivalent to the electricity required to power 61,000 U.S. households. The wind farm represents the biggest long-term commitment to renewable energy use of any food manufacturing business in the United States.

The wind farm is one of the ways Mars is achieving its goal to make its operations ‘Sustainable in a Generation’ by eliminating greenhouse gas emissions by 2040. In the shorter term, Mars has committed to reduce fossil fuel energy and greenhouse gas emissions by 25 percent by 2015, using 2007 as its baseline year. The Mesquite Creek wind farm will enable Mars to meet this 2015 goal.

Development of Mesquite Creek began in 2008 on the 25,000 acre site, which is located in Borden and Dawson Counties, TX, about eight miles from Lamesa. Blattner Energy Inc. is constructing the wind farm, and electricity will be generated via 118 1.7 MW GE turbines. Turbine delivery is scheduled to begin at the end of the summer, with commercial operations expected to commence in the second quarter of 2015.

NRG Energy and MidAmerican Solar Complete Agua Caliente, the World’s Largest Fully Operational Solar Photovoltaic Facility

NRG Energy, Inc, through its wholly-owned subsidiary NRG Solar, along with partner MidAmerican Solar announced they have achieved substantial completion at their Agua Caliente Solar Photovoltaic Facility, a 290 megawatt (MW) photovoltaic facility located on 2,400 acres of land between Yuma and Phoenix, AZ. The electricity that is generated by the station, which can support 230,000 homes at peak capacity, is being sold to Pacific Gas & Electric Company (PG&E) under a 25-year power purchase agreement.

Agua Caliente is the largest of 10 operational utility-scale solar PV facilities in three states in which NRG has ownership interest. Agua Caliente is also one of several NRG assets that are subject to a Right of First Offer Agreement between NRG and its publicly owned subsidiary, NRG Yield, Inc. First Solar, Inc. designed and constructed the project using its advanced thin-film photovoltaic modules and will operate and maintain the facility for NRG and MidAmerican Solar.

TEP Breaks Ground on Solar Project Through Innovative Partnership with Fort Huachuca

Tucson Electric Power (TEP) is developing a large solar array at Fort Huachuca in Sierra Vista, AZ, through an innovative partnership that will help the U.S. Army achieve its renewable energy and energy security objectives.

The array is expected to have a capacity of approximately 18 megawatts (MW) when it comes online later this year. That's enough power to satisfy one-quarter of the base's energy needs and is equivalent to the annual electric needs of approximately 3,100 homes.

TEP will own and operate the array, providing Fort Huachuca with unmatched reliability and a streamlined development process available only through this unique partnership. TEP has contracted with E.ON Climate & Renewables, a partner on other successful solar projects, for the system's construction.

The Fort Huachuca system will be larger than any existing solar array on any U.S. Department of Defense base in the world. Once in operation, it will serve as the largest single solar resource owned by TEP. The system will offset more than 58,000 tons of carbon dioxide per year while reducing other emissions associated with generating an equivalent amount of power with fossil fuels.

The system at Fort Huachuca will be connected to an existing substation through a single interconnection on TEP's side of the meter. Any excess energy the system generates will flow back into the grid for use by other TEP customers.

$60 Million Dedicated for Solar Energy on Long Island

In an effort to continue the success of Long Island's solar programs, Governor Andrew M. Cuomo announced, as part of the statewide NY-Sun Initiative, a $60 million investment to support the Long Island solar industry's transition to PSEG Long Island.

PSEG Long Island will partner with NYSERDA to locally implement the statewide NY-Sun program. NY-Sun Initiative is a collaborative effort among public-private entities who are all working toward the common goal of achieving greater acceptance of and advancing the use of solar power in New York State.

NYSERDA will more than double the proposed NY-Sun Initiative allocation for the Long Island region from $28 million to $60 million. The maximum size of the photovoltaic system (PV) eligible for incentives will increase from 10 kilowatts (kW) to 25 kW for residential homes and 100 kW to 200 kW for commercial businesses.

The Solar Pioneer and Solar Entrepreneur programs will be replaced with NYSERDA's Megawatt Block program, which allocates MWs to specific regions of the State; breaks those regional MW targets into blocks to which incentives are assigned; and awards incentives based upon the block in effect at the time. NYSERDA and PSEG Long Island are currently working out the details that would enable PSEG Long Island to be the local administrator for the MW Block program.

Iowa Cows Generate Electricity with Help from Alliant Energy

Iowa customers of Alliant Energy are getting some of their electricity from cows.

The more than 2,400 head of cattle at Sievers Family Farms near Stockton are among the latest to start generating renewable energy in the state. In total, Alliant Energy has partnered with 520 Iowa customers to create renewable electricity for themselves and the energy grid.

The digester at their farm uses the gas from the cattle manure as a fuel to power an electric generator. This unit provides up to one megawatt (MW) to both the farm and Alliant Energy's electrical grid. When the generator is able to run, it can create the same amount of energy that would power about 1,000 homes.

The digester is just one way renewable energy is being generated in Iowa. When added up, Alliant Energy's Iowa customers will have the ability to generate more than 23.3 Megawatts (MW) of renewable energy this year, when conditions are right. Renewable energy requires certain environmental thresholds to work effectively. Often, these include direct sunlight, strong winds, or animals in the case of the Sievers' farm.
