However, depending on the composition and operating conditions of the feed gas, different amines can be selected to meet the product gas specification. Amines are compounds formed from ammonia (NH3) by replacing one or more of the hydrogen atoms with another hydrocarbon group. Amines are ...
A waste gas containing SO2 and SO3 is washed with water and ammonia; the resulting solution of ammonium sulfites and sulfates is heated for converting the sulfites to SO2 and NH3, the sulfates are reacted with a reducing agent for producing additional SO2 and all the SO2 is reacted with H2...
