The Chemical Productions Recycle In Coking Industry And Cleaner Production Analysis

See from the coke ovens that used in the world currently, the modem techniques of coking is divided into the two major types. One is the traditional mechanization coke oven with the chemical productions, and the other one is non-recycle coke oven. This paper contrast mechanization coke oven with the chemical productions and non-recycle coke oven by techniques and economical benefit; and concludes the status of coke product and chemical production recycle in cording to the monitor reports of some coking enterprises in our province.Because of the complicated production process, the discharge of the organic waste waters and organic exhaust in coking, the management of pollution brought the heavy economy burden to the coking enterprises. So the key of the problem-solving is bringing the cleaner production into effect. In our province, the coking industry has been the mainly industry in some area in the west. So bringing the cleaner production into effect in coking industry is very important. This paper analysis the cleaner production in coking, which is takes the project with 100×10⁴ t/a coke of Qinghua Group and the project 50×10⁴t/a CH₃OH of Shenghua Group as examples.
