采用焦化加工路线的炼油厂增效措施分析与应用

某炼油厂为提高经济效益，通过分析焦化加工路线的特点，发现焦化加工路线具有加工原油品种选择范围宽，装置建设投资成本低和运行操作费用低的效益优势，同时具有产品结构差和产品性质差的效益劣势。该炼油厂充分发挥焦化加工路线的效益优势，采取优化原油采购、减产石油焦、增产汽油和喷气燃料以及节能降耗、保持CFB锅炉长周期运行等措施，大幅降低了原油采购成本，优化了产品结构，降低了操作费用，与设计方案相比，按2015年实际产品结构计算，经济效益提高10.33亿元/a。

ANALYSIS AND APPLICATION OF MEASURES OF INCREASING BENEFITS FOR COKING ROUTE REFINERY

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.
