Sinopec's Zhenhai and Tianjin ethylene plant projects will use the Zimpro wet air oxidation system to destroy odorous sulfide pollutants and generate a biodegradable effluent that can be discharged to conventional biological wastewater treatment. The Zhenhai plant will treat approximately 18.2 m³/hr of wastewater and the Tianjin system,14.5 m³/hr.
The Zimpro wet air oxidation process will also break down complex organic contaminants, such as phenols, to either carbon dioxide and water, or biodegradable organics.
