摘要:
分析了高硫原料对加氢裂化装置运行的不利影响,利用Aspen HYSYS软件建立了系统模型,对增设循环氢脱硫系统前后的主要含硫物料H2S含量、H2S平衡以及贫胺液用量等关键参数进行了模拟计算。结果表明:通过增设循环氢脱硫系统,使循环氢中 H2S 体积分数降低94.5%,主要含硫物料H2S含量均大幅下降;汽提塔蒸汽用量由3.30 t/h降至2.20 t/h,实现了轻、重石脑油的合理切割;循环氢脱硫系统总投资1 900万元,创效865万元/a,投资回收期为2.33 a。
Abstract:
The adverse effects of high sulfur feed stock on the operation of hydrocracking unit were analyzed, and a system model was established by using Aspen HYSYS software. The key parameters such as H2S content of main sulfur-containing materials, H2S balance and the amount of lean amine solution were simulated before and after the addition of recycle hydrogen desulfurization system. The results showed that the volume fraction of H2S in recycle hydrogen was reduced by 94.5%, and the content of H2S in main sulfur-containing materials was greatly reduced. The steam consumption of stripper was reduced from 3.30 t/h to 2.20 t/h, and the reasonable cutting of light and heavy naphtha was realized. The total investment of the recycle hydrogen desulfurization system was 19 million yuan, creating benefits of 8.65 million yuan/a, and the payback period was 2.33 a.
