WKV/BEE CSCR system is a system based on Activated Coke as catalysis and adsorption media. This technology is simple and a one step process for multiple gases treatment. This is a modular and compact system is good for retrofit application, as the space requirement is much smaller than other system. WKV/BEE system using counter current absorber. This system produces no wastewater, no byproducts, and is an energy economic system.
