Air Pollution Control

Dry powdered materials such as hydrated lime, sodium bicarbonate, trona, and activated carbon are injected into a flue gas stream at many utility and industrial fossil fuel-fired boiler facilities. We specialize in Dry Sorbent Injection (DSI) technology to remove common pollutants including acid gases (S02,S03/H2S04, HCL), volatile organic compounds (VOCs), and metals (Hg, As).

expertise & Experience

We partner with clients to analyze and plan for DSI “balance of plant” effects to increase throughput and reduce pollution. We have a thorough understanding of complex federal and state environmental regulations and help clients navigate the complicated compliance process. We are known for our in-house engineering capabilities, cutting-edge technology, Lodge Cottrell division, and diverse network of sorbent providers.
