Abstract

In this paper, retrograde condensation is considered using binary mixtures of hydrocarbons as an example. The feasibility of numerical simulation of this phenomenon using the direct energy minimization is demonstrated. To verify the calculations, similar simulations are performed using the ‘‘classical’’ iterative algorithm for calculating vapor–liquid equilibria in hydrocarbon mixtures. A comparison of the simulation results with the data of physical experiments confirms the prospects of using the direct energy minimization method for phase transition calculations in hydrocarbon mixtures.
