Hi there!
I am working on a simulation for a gas conditioning system. I am confronting the following problem:
When I expand the gas from 1330 psig down to the desired pressure in order to achieve the required properties (i.e., %methane), the simulator predicts gas hydrates in the two-phase stream that enters to the two-phase separator.
I have the following doubt: Can gas hydrates exist in two phase streams?
Moreover, I am feeding methanol to dissolve the hydrate. The gas stream that is flashed in the separator does not have hydrates, but in order for the hydrate to dissappear in the two-phase stream entering the separator, I have to supply too much.
In addition to that, there are three models to predict hydrates: symmetric, assymmetric and vapor only. Which one would be the best to predict in my model?
Any advise is well appreciated.
