Until recently, the price relationship between the MEA and MDEA sinks did not give good reasons for the recommendation metildietanolaminovogo scavenger for trapping hydrogen sulfide from coke oven gas. In this paper we investigate the features of the interaction of MDEA with specific pollution coke oven gas. A unique choice MEA or MDEA absorber depends on the current price of a supplier on the absorber, since the cost of the absorber in the total operating costs account for 40-44% (according to Ukhin). The use of any amine absorber must be accompanied by a high degree of purification of coke oven gas in previous installations - ammonia, benzene, and the offices of UGS KGH. For MDEA, this conclusion is particularly relevant, in addition, shall be no carryover of the absorption of oil from benzene scrubbers must be installed and work effectively electrostatic coke oven gas. Necessary to organize additional washing of coke oven gas with water immediately prior to amine plant, including to reduce the income of hydrogen cyanide.
