Desulfurization of circulating hydrogen during hydrogenation
Thread Content
Guys, has anyone used PROII to simulate a circulating hydrogen desulfurization tower? Which thermodynamic equation was used? I’ve read in some literature that the amine package included with PROII provides relatively high simulation accuracy, but it cannot recognize virtual petroleum components, so it’s not possible to simulate them. Does anyone have any other methods? Please let me know. Thanks!
Here’s how I resolved it: 1. Simplify the desulfurization unit by using a component separator； 2. Open another file to handle the desulfurization unit separately. Looking forward to experts' opinions
Since there are very few reports in the literature on this topic, I welcome everyone to join the discussion in order to help me resolve my doubts. Please!
How can there be virtual petroleum components in the circulating hydrogen desulfurization tower? Your simulation isn’t correct, is it?
Answering the person above. The poster wants to combine the desulfurization unit with other components such as the reaction section in one model.
In that case, a component separator will work just fine. Keep it simple – no need to complicate it! !
Because of the hydrodesulfurization process used, the high-pressure gas will contain a small amount of virtual components.
Because the hydrogen in the hydrogenation process is constantly in circulation, using a component separator to remove the petroleum components would cause an overall imbalance in the material flow.
