摘要
随着劣质原油加工比例的不断增加及日益严格的环保要求,如何减少、治理炼厂延迟焦化装置废水产生的污染问题,已受到越来越多企业的关注和重视。对当前国内炼厂延迟焦化装置的主要废水来源做了较为详细的说明,并依据废水的性质及特性进行了分类(分为含油废水、含硫废水,生产废水三类。其中含油、含硫废水占延迟焦化总污水的90%以上)。还结合炼厂工业生产实际,对比分析了当前炼厂延迟焦化装置处理各类废水的主要方法。
With the increasing proportion of inferior crude oil processing and more stringent environment protection requirements,more and more domestic oil refineries are paying special attention to the pollution problem resulting from decreasing and treating the wastewater in the delayed coking unit.This paper makes a detailed discussion on the origins of the wastewater.According to the properties,it classifies the wastewater into three categories covering wastewater containing oil and sulfur and industrial wastewater with the former two cover over 90%in total delayed coking wastewater.Meanwhile,combining with actual production of refinery industry,the paper compares and analyzes the main treatment methods for various kinds of wastewater in delayed coking unit in current refineries.
