直馏煤油低压加氢精制生产3号喷气燃料技术开发
|
摘要
拓宽直馏煤油馏分(提高直馏煤油的终馏点)可以增产喷气燃料,但馏分拓宽后会导致原料油的硫、氮含量增加,同时也会导致烟点降低和冰点升高。对馏分拓宽的直馏煤油进行低压加氢工艺试验,研究结果表明,较高的反应温度、较低的空速有利于氮化物的脱除,但在高温情况下会导致产品的色度下降。对低压加氢工艺流程进行优化升级,开发了生产喷气燃料的低压直馏煤油加氢新工艺。与常规工艺相比,该新工艺具有较强的加氢性能,同时还具有改善喷气燃料产品颜色的性能。
Broadening the final distillation point of straight-run kerosene is an important way to increase jet fuel production.However,the broadened fraction has higher sulfur and nitrogen content,lower smoke point and higher freezing point.The hydrofining test showed that the high reaction temperature and low space velocity under low pressure are favor to remove nitrogen compounds,but not for saybolt color of the product.A new low pressure hydrofining process was developed to treat the broadened SR fraction.The results indicated that the new process has a better performance for improving the color of jet fuel product,compared with the conventional process.
