Phase Envelope

The Phase Envelope feature allows us to generate a phase envelope for a composition based on our fluid model.

In the picture below, we see that the Phase Envelope feature is located directly below the equilibrium calculation. As with all these features, it can also be directly accessed from the fluid model overview.


Inputs

Since the the phase envelope describes the fluid at a range of temperatures and pressures, it only requires a composition and an associated EOS.

We also have to make sure that our composition matches the component slate given here, which we could copy from the 'adjusted compositions for the EOS', or our equilibrium calculation if we have already filled in a composition there.

Results

Once we click 'Run Phase Envelope' the software will yield our phase envelope as shown below.


We can also download this graph as a .png or .svg file by clicking on the three dots to the right as demonstrated under.


Next Steps

Having ran a phase envelope, we could move on to simulate experiments with the Synthetic PVT Lab.
