| Abstract: | A closed-cycle process of coke-cooling water was developed,which integrated multilevel condensation,gradient separation and mechanical purification of pollutants.The process was used in 1 Mt/a coke-cooling water system.The running results indicate that the recovery rates of wastewater, slop oil,coke and volatile organic compounds are all 100%.Compared with other homogeneous processes at home and abroad,the process has the advantages of higher recovery efficiency,lower investment,better economic and social b... |
