炼厂提高延迟焦化装置处理能力方法

Ways of improving delayed coking unit's processing capacity for oil refinerys

针对焦化装置大部分都满负荷或超负荷运行,但仍不能满足炼厂渣油加工能力的要求,需要进一步提高装置处理能力的问题,介绍了延迟焦化工艺这种应用最广的一种渣油加工技术,解决国内炼油企业加工的原油密度逐渐增大,重油产量大幅增加的问题,而通过焦化装置加工过剩渣油,提高炼厂效益.主要通过探讨两个方面提高焦化装置处理能力:一是增加设备进行扩能改造;二是优化操作条件进行负荷转移,提高渣油转化能力.

At present,most of the Coking Units are running at full or overload capacity,but it can’t still meet the requirements for the processing capacity of residual oil.So we need to further improve devices’processing capability.The delayed coking process is most widely used as a residual oil processing technology that can solve the problem with an great increase in crude oil density and the production of heavy oil for domestic oil refining enterprises.All the refineries want to process the excess residual oil with Coking Units for improving a oil refinery’ efficiency.This paper discusses two main aspects to improve the Coking Units’processing capacity,firstly,investing additional equipment for expansion and reconstruction;secondly,optimizing operating conditions to transfer the load for improving the processing capacity of residual oil.
