延迟焦化装置处理含油污泥的技术应用

摘要

介绍了中国石油乌鲁木齐石化公司炼油厂采用1.2 Mt/a延迟焦化装置的焦炭余热掺炼含油污泥的技术。采用该技术在焦炭塔冷焦期间，成功处置了含油污泥，并根据掺炼过程中出现的问题，提出了相关注意事项及对策。实际应用结果表明，采用该技术处理含油污泥达到了无害化、资源化和减量化的处理原则，降低了危险废物的处置费用，是炼化企业清洁生产的可行之法。适量掺炼含油污泥对延迟焦化装置的平稳生产和石油焦产品的质量无较大影响，石油焦产品仍能满足3B级产品的质量要求。%Oily sludge was treated through blending process in a 1.2 Mt/a delayed coking unit of Urumqi Petrochemical Company utilizing used heat in coke. Aimed at the problems in the blending process,relevant measures were put forward. It was showed that,through practical application, the oily sludge became harmless and could be used as resource,and the cost of the waste disposal was reduced. By blending the right amount of the oily sludge,the delayed coking unit could smoothly produce petroleum coke product which could meet the quality requirements.
