Abstract

Technology of the final cooling of coke gas, its ecological and technological aspects is viewed. The ways of reduction in the quantity of ejections into the atmosphere are represented. The experience of closing cycle in different coke-chemical enterprises is analyzed. Results on an improvement in the quality of the circulating water of the closed cycle are examined via the scavenging of cycle and processing of water on the ammonium column with the transfer to the biochemical effluent plant. Conclusions about the need of closing of aqueous cycle and control of salinity in the recirculation water of final gas cooler are made.
