Coke Manufacturing - International Finance Corporation
Wastewater is generated at an average rate ranging from 0.3 to 4 cubic meters (m 3) per ton of coke processed. Major wastewater streams are generated from the cooling of the coke oven gas and the processing of ammonia, tar, naphthalene, phenol, and light oil. Process wastewater may contain 10 milligrams per liter (mg/l) of benzene,
