An ethylenediamine (EDA) process developed for the purification of coke-oven gas of acid components is a cyclic process. The process can recover H/sub 2/S and HCN simultaneously. Laboratory and pilot plant data on the removal of HCN from coke-oven gas using this process and on the processing of the spent scrubber liquor are presented. Ethylenethiourea is recoverable from the spent liquor.
