提高柴油收率的优化措施

针对市场阶段性柴油需求量大的情况,某炼油厂通过分析影响柴油收率的因素,采取提高2套常减压装置常三线95%馏出温度,适当降低300×10^4 t/a重油催化裂化装置反应温度、平衡剂活性,提高120×10^4 t/a重油催化裂化装置催化柴油95%馏出温度等优化措施后,柴油平均收率较实施前提高了1.87%,有效的增加了柴油收率,满足了市场需求。

Optimization measures for improving diesel yield

In view of the large demand for diesel in the market,through analysis of the factors affecting the diesel yield,a refinery adopted optimization measures such as increasing 95%distillation temperature of atmospheric third line diesel in atmospheric and vacuum distillation unit,appropriately reducing the reaction temperature and the activity of the balancing agent in the 300×10^4 t/a FCC unit,and increasing 95%distillation temperature of the catalytic diesel in the 120×10^4 t/a FCC unit to make the average yield of diesel increased by 1.87%,which effectively increased the yield of diesel and met the market demand.
