Abstract
A liquid suspension comprised of ferrous sulfide particles and method of using the same for the removal of selenium from industrial gas. Said liquid suspension may be (1) directly injected, or (2) coated onto or into a substrate and then injected into an industrial gas containing selenium to remove said selenium from the industrial gas stream in a dry scrubber system. Said liquid suspension of ferrous sulfide particles may also be used to remove selenium contained in industrial gases in a wet scrubber system.
