Simulation of the water pocket in the distillation column reflux drum in refineries
Thread Content
The overhead reflux tanks in distillation columns in refineries usually have water separation packages, which results in the composition of the overhead reflux being different from that of the liquid product stream. How can this situation be simulated in ASPEN? How do you calculate the water cut out from the water cutting pack in the simulation process? I hope to learn from everyone*
Go to the top so that everyone can see it; I notice that others usually omit this part, and as a result the components involved in the backflow change, which means the simulation results no longer serve as a reference
What is a water-cutting bag? Separate the aqueous phase? If that’s the case, then you can use a 3-phase separator. As you mentioned, many simulations don’t include a water separation unit; it’s likely because they didn’t take water into account in their feedstock.
You can also use the Decanter module
