Description:Despite recent improvements in engine designs to reduce pollution, diesel engines continue to emit large amounts of NOx, particulates, hydrocarbons (HCs), and other pollutants. Pollution is a problem with both stationary and mobile diesel engines. No completely satisfactory commercial control technology exists today to treat diesel engine exhaust gases.
Sorbent Technologies Corporation recently developed a simple regenerable filter system, proven successful in treating aircraft engine emissions in jet engine test cells. The system controls NOx, hydrocarbons, small particulates (including PM2.5 particles), and SO2. Sorbent Technologies proposes a Phase I project to develop the filter system to control stationary diesel engine emissions with the added capability of regenerating the principal filter bed in place. This added capability will permit the system to be operable almost perpetually with little or no attention. Phase I will include a laboratory demonstration of the new technology and recycling runs involving up to 200 sorption-regeneration cycles to observe the effectiveness of the system and the robustness of the sorbents. Phase II will include a process scaleup and a commercial or near-commercial scale demonstration of the new technology.
A goal long sought by stationary diesel engine manufacturers and operators is a relatively simple, low-cost, low-maintenance pollution control system. This goal is believed achievable with the proposed new technology for both new and retrofit applications. Many hundreds of thousands of stationary diesel engines are currently in use. Although these engines are durable, reliable, fuel-efficient, easy to repair, and inexpensive to operate, they cause pollution. Success in this project should solve this major problem and lead to increased use in the future of cleaner diesel engines.
