Investigation of Different Equipment Setups for Ammonia Wash and Desulfurization

摘要

The coke oven gas (COG) scrubbers and the subsequent scrubbing liquor recovery is the centrepiece of a by-product plant for removal of ammonia, hydrogen sulfide and hydrogen cyanide using the ammonia wash system. There are several different options to design the scrubbing and wash water treatment plants of a by-product plant, applying different types of columns and internals as well as and modes of operating the interacting units.
