为了增加喷气燃料产量提高企业的经济效益，利用加氢裂化装置原料适应范围广的特点，加氢裂化装置掺炼催化裂化柴油、常二线及常三线提高装置负荷，通过提高装置负荷增产喷气燃料，同时根据各工况原料性质的变化优化各工况操作条件最大限度增产喷气燃料。与设计工况相比，掺炼催化裂化柴油、常二线及常三线工况喷气燃料收率分别增加4．30，5．80，0．94百分点，而且随着原料范围的拓宽，装置负荷及喷气燃料的产量大幅提高；通过计算各工况的经济效益发现，在当前的市场情况下，增产喷气燃料方案是加氢裂化装置优化的方向。%To increase jet fuel production and improve refinery benefit,the WEPEC broadened its hydrocracker feedstocks by processing LCO,CDU 2 nd and 3 rd cuts. Meantime,operation conditions are optimized according to the feed properties to maximize jet fuel. As the raw material range widening,the unit load and the output of jet fuel is improved significantly. After optimization,the jet fuel yield increa-ses by 4.30%,5.80% and 0.94% using the blending feed with LCO,CDU 1 st and 2 nd cut,respectively, compared with design requirement. The practice suggests that increase of jet fuel production can in-crease the benefit of the hydrocracking unit in the current market situation.
