A great deal of information and analysis of gas turbine air intake systems was displayed at the Filtration and Power-gen Shows earlier this month. At EUEC and Electric Power we will also create a GT Air Treatment route maps.

For simple-cycle or combined-cycle gas turbines, JM CO catalyst reduces CO by over 90%and also reduces VOC and toxic compounds like formaldehyde.

Johnson Matthey’s Stationary Emissions Control (SEC) LLC reports that its oxidation or CO catalysts for simple and combined-cycle gas turbine applications have exceeded two GW of generating capacity in two years.

Johnson Matthey introduced oxidation catalysts for gas turbines in the 1970s. Today, its CO catalysts — used in some of the most environmentally challenging applications — have achieved durability of 10 or more years of continuous operation.

Jeff Sherman, Johnson Matthey SEC LLC President, said, “Catalytic emissions control is the best available technology for reducing pollutants from gas turbines. Our latest installations include some of the largest simple-cycle turbines to ever use CO catalyst, as well as some of the largest combined-cycle turbines in the U.S. during the last two years. “Our CO catalysts are routinely used by the major manufacturers of gas turbines and HRSG fabricators,” added Sherman. “We are in a unique position to offer both brazed catalyst to help the catalyst survive higher turbulence in simple-cycle turbines, as well as un-brazed catalyst, which is ideal for combined-cycle applications.”

For easier installation, Johnson Matthey recently introduced its novel “Drop-In” design for CO catalysts that includes full reactor width catalyst modules. The catalyst is pre-loaded at the factory so that the modules can be installed within hours instead of days at the jobsite. Johnson Matthey also provides field support during catalyst inspections, bed rotations, and partial bed replacements.

Johnson Matthey CO catalysts are formulated with Platinum GroupMetals (PGM’s) to achieve maximum conversion of pollutants at gas turbine temperatures. Sherman says “It is the highest activity catalyst available plus its flow-through metal monolith design delivers the smallest catalyst package and the lowest backpressure in the industry. Side reactions, such as NO to NO_2,are minimized.”

“Our core expertise in catalysis has allowed us to stay at the cutting edge of new catalyst development meeting the challenges of ever increasing regulatory requirements for gas turbines,” Sherman added.

Air Filter Market Will Exceed $ 6.9 Billion in 2014

The market for filters to purify air recirculating within commercial and industrial facilities as well as residences will exceed $6.9 billion next year. This is the latest forecast in Air Filtration and Purification published by the McIlvaine Company. www.mcilvainecompany.com

Industry	2014
TOTAL	6,934.62
Bioclean	547.92
Commercial	1,619.41
Electronics	615.67
Cabin air	1,098.98
Other Industries	1,614.97
Power	437.90
Residential	999.76

The commercial market will be the largest due to the large volume of air which must be purified. It is also a function of the selection of relatively high priced filters. The cabin air market includes the air in the breathing zone in land vehicles as well as ships and oil platforms.

The power market reflects the use of inlet air filtration for gas turbines. The filters used on

coal-fired power plant stacks are included in a separate McIlvaine report. The gas turbine intake market is forecast to double over the next few years. One reason is the growing use of gas turbines for power generation as well as for industrial power. The bigger reason is the movement toward high efficiency filters and away from medium efficiency filters.

New studies show that with the latest generation of high performance turbines filtration efficiency is critical. Very small particles build up on the rotating surfaces and cause a loss in turbine output. Switching to filters with up to four times the cost of existing filters will make such a difference in turbine performance as to quickly justify the higher cost.
