摘要
An algorithm for calculating the vapor-liquid phase equilibrium for multicomponent gases is presented. A six-component gas mixture is considered. The algorithm for calculating phase equilibrium is based on the solution to the Soave-Redlich-Kwong equation of state for real gases. An iteration algorithm for updating phase equilibrium constants is used. The total vapor fraction is determined using the solution to the Rachford-Rice equation. The difficulties of developing such algorithms are considered in full detail. The derived solution is compared with results obtained in the commercial package HYSYS (version 3.2) when the Soave-Redlich-Kwong equation is also used.
