NeqSim is a library for calculation of fluid behavior, phase equilibrium and process simulation. This project implements the .Net interface to NeqSim.
Program to calculate phase boundaries of multicomponent systems using Equations of State. WIP now suporting PT envelopes and PX envelopes with partial three-phase-behaviour
::A simple phase EQ extractor for gas hydrate researchers::
It is envisaged to eliminate these light constituents by distillation . A study of the operating conditions of the process can be done in pseudo-binary: we assimilate the C7 cut to n-heptane and the light ones to ethane. We wish to construct the diagrams [T-x-y] and [x-y], [h-x-y] of the ethane-n-heptane binary under a fixed pressure of 13.78 bars.
