HYSYS hydrorefining simulation calculation

Question: In HYSYS hydrogen refining simulation calculations, how is hydrogen circulation carried out? This post was last edited by visavis on 2009-4-13 09:23
During the steady-state process, this cycle needs to be simulated using Recycle in order to solve for the tearing flow.
May I ask the experts upstairs, what model should be used for more accurate simulation? The PR recommended by HYSYS? Or something else? It is mainly about the balanced data for high and low scores: a pressure of 6.0 Mpa, a hydrogen-to-oil ratio (V) of 350:1, a raw material boiling range of 180–240, 0.2% S…… and so on
In such cases with HYSYS, we generally use the PR equation; using the SRK equation also results in not too large errors. Additionally, the high and low pressure processes you mentioned seem to refer to hydrocracking rather than hydrorefining – is that correct?
It’s hydrogenation refining, and then it’s used for molecular sieve dewaxing… Thanks for the advice!
I wonder if the original poster has simulated the hydrogenation refining process?
Has my bro managed to simulate it yet?
