Abstract

This paper is the manual for an open source software that performs multiphase split calculations. The provided software performs two-phase, three-phase and four-phase flash calculations. The calculations are based on the Peng-Robinson equation of state (PR-EOS). The four-phase calculation is achieved using a geometrical solution in 3D for Rachford-Rice equations. The paper includes a link to download the software and a step by step instructions are provided to replicate an example from the literature.
