FCC汽油加氢装置国V升级改造情况的比较

Comparison of FCC Gasoline Hydrogenation Units for Upgrading of China V Standard Diesel

本文从流程设置、操作条件、操作性能、产品质量和能耗等方面对改造后的A公司50万吨催化汽油加氢装置和B公司50万吨催化重汽油加氢装置的情况进行了比较。改造后A公司投资和能耗较高,但装置操作灵活稳定有利于调整产品质量。改造后B公司的投资和能耗相对较低,但由于反应部分的三个反应器从单一热源取热,所以装置操作灵活性差。

In this paper,two upgrading gasoline hydrogenation units were compared,which are company A＇ s 500,000 ton/year gasoline hydrotreating unit and company B ＇ s 500,000 ton/year gasoline hydrotreating unit.The process settings,operating conditions,operating performance,product quality and energy consumption were studied and compared.The results showed that the investment and energy consumption of company A are relatively high,but the operating flexibility and stability of device are conducive to the adjustment of product quality.The investment and energy consumption of company B are relatively low,but the operating flexibility of the device is poor.This is because that the three reactors of the reaction part utilize a single heat source as heat supply.
