Phase Envelope for Light Hydrocarbons

Initial Conditions

Do you wish to input a guess for a T,P point inside the phase boundary? This should only be necessary if the mole fraction-weighted critical point does not fall within the phase envelope or falls near a phase boundary and the algorithm used to generate points on the phase boundary fails.

Yes
No

Temperature: K

Pressure: kPaa

Mixture

Select the components for your mixture from the lists below and enter the mole fraction of each component in the field to the right. If the mole fractions do not sum to one when you are done, they will be re-normalized for you.
