摘要: 延迟焦化冷焦过程中用高浓度污水替代1.0 MPa蒸汽进行冷焦,不仅可以降低使用蒸汽而产生的装置能耗,而且可以处理部分污水处理厂难以处理的高浓度污水,减少污水排放。在中国海油舟山石化有限公司2.4 Mt/a的延迟焦化装置的应用表明,可以节约能耗237.0×103 MJ/d,减少高浓度污水外排75 t/d,是一项节能环保的新工艺。

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
