Fractionation column blocked discharge psv sizing case
Fractionation column blocked discharge psv sizing case
(OP)
I have a demethanizer column and im sizing the psv for the blocked vapor outlet case.
Ive simulated the scenario in hysys with max reboiler duty allowed for in the model.
Is steady state simulation the correct approach for this scenario?
Thanks.

However, the other controlling case for this PSV would be the exit flow from the expander when running at max normal speed, with max normal feed pressure and min normal feed temp to the expander.
