Abstract: The commercial application of high concentration wastewater in cooling coke process instead of 1.0 MPa steam in a 2.4 Mt/a delayed coking unit of CNOOC Zhoushan Petrochemical Company was introduced, which not only can reduce the use of steam and unit energy consumption, and also can handle some high concentration wastewater that is difficult to treat in swage water treatment plant. The application results showed that the reduction of energy consumption is about 237.02 x 103 MJ/d, the discharged out wastewater is reduced about 75 t/d.
Key words: delayed coking, high concentration wastewater, coking drum, steam
