Clark, M., Siemens Water Solutions; Xia, N., Sinoec Zhenhai Refining & Chemical Co.

As China’s largest integrated refinery, Sinopec’s Zhenhai Refining & Chemical Co. (ZRCC) plant can process approximately 23 MM metric tpy of crude oil. The plant produces more than 50 fuel and chemical products, including different grades of gasoline, jet and diesel fuels, asphalt and polypropylene plastics, as well as more than 1 MM metric tpy of ethylene. The latter generates spent caustic, one of the world’s most toxic wastewaters.
