|
摘要
悬浮床加氢装置对于处理高含固、高沥青质含量的煤焦油有着明显的优势和诸多优点,对悬浮床加氢工艺进行了简单的介绍,并着重就加氢工艺关键技术参数之一氢油比对加氢装置不同运行阶段的影响进行了较为详细的分析:较低氢油比有利于装置顺利开工,在较高氢油比条件下,有利于装置停车阶段催化剂的卸出,适中的氢油比有利于装置的长期稳定满负荷运行。
The slurry bed hydrogenation unit has obvious advantages in treating coal tar with high solid content and high asphaltene content. The hydrogenation process of slurry bed was briefly introduced,and the influence of hydrogen-oil ratio,one of the key technical parameters of hydrogenation process,on different operation stages of hydrogenation unit was analyzed in detail. The lower hydrogen-oil ratio was beneficial to the plant start-up,the higher hydrogen-oil ratio was beneficial to the catalyst discharge,and the moderate hydrogen-oil ratio was beneficial to the long-term stable operation of the plant.
