Abstract:

In order to increase economic benefits of a coking type refinery, the advantages and disadvantages of the technical rout are analyzed. It is found that the coking type refinery has advantages such as flexible crude oil procurement, lower construction investment and lower operating cost, but poor product distribution and product quality compared with products of hydrogenation route refinery. The refinery adopts measures to optimize crude oil procurement, reduce the petroleum coke, and produce more gasoline and jet fuels, raise energy efficiency, reduce consumption as well as keep long term operation of CFB boilers. As a result, compared with the design scheme, an annual benefit of 1.033 billion yuan are realized according to the product slate in 2015.

Key words: delayed coking, processing route, economic profit, production optimization
