炼油厂增产喷气燃料技术及应用分析

摘要

增产喷气燃料、压减柴油是适应国内成品油市场变化和炼油厂调整产品结构、提质增效的关键.提高常减压蒸馏装置和加氢裂化装置煤油收率是当前炼油厂增产喷气燃料的主要途径,但受到常减压蒸馏装置常一线油拔出率不够、加氢裂化产品方案不匹配等多方面因素的影响,制约了增产喷气燃料潜力的发挥.分析了当前炼油厂增产喷气燃料的瓶颈,介绍了加氢裂化最大量生产喷气燃料以及直馏柴油加氢裂化生产喷气燃料技术,同时对技术应用效果进行了分析总结,为炼油厂增产喷气燃料、压减柴油提出了相应建议.%To increase jet fuel and reduce diesel production was the key to refinery to adapt to changes in domestic oil market by adjusting product structure and improving product quality and operation efficiency.Increasing the kerosene yield of CDU and hydrocracker was the main way to increase the production of jet fuel.However,the jet fuel production was limited by the yield of No.1 side-line of atmospheric distillation tower and hydrocracking products solutions.This paper analyzed the current bottlenecks in jet fuel production of refineries,described the technologies for maximum production of jet fuel from conventional hydrocracking and SR diesel hydrcracking.Meanwhile,the technology application effect was summarized.Based on the above analysis,some suggestions were suggested.
