Abstract
The environmental risk due to atmospheric pollution from coke plants is assessed for both organized and unorganized sources of emissions in the byproduct-capture, benzene-rectification, and tar-processing shops and the system for biochemical wastewater treatment. It is found that 19.4% of all the organized sources correspond to acceptable levels of chronic noncarcinogenic environmental risk; 30% to high risk; and 50.6% to very high risk. A system of hydraulic breather valves is proposed for utilization of the emissions in the byproduct-cap ture shop. For the tar-processing and benzene-rectification shops, delivery of the emissions to the direct coke-oven gas line is recommended. For the emissions from the biochemical wastewater treatment system, collection and purification by sorption and biochemical treatment is proposed.
