Computer simulation of interphase mass transfer processes in natural hydrocarbon mixtures, as well as their qualitative laboratory studies, allow the specialist to study the processes in the oil reservoir more deeply. Today, the industry uses a number of software solutions (PVTSim, WinProp CMG, Aspen HYSYS, etc.), simulating interphase mass transfer in oils, gas condensate mixtures, etc. In most of these industrial software products, a method for calculating the phase equilibrium based on the equation of state of a multicomponent hydrocarbon system is implemented (flash calculations). For this purpose, as a rule, various versions of the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) cubic equations of state are used. ...
