Modification of Quasi-Newton Successive Substitution Method for Calculating Phase Equilibria of Hydrocarbon Mixtures Taking into Account the Capillary Pressure Jump
摘要
Abstract
A modification of the Quasi-Newton Successive Substitution method is presented, which is used to calculate phase equilibrium with a capillary pressure jump. To check the correctness, a calculation results of the considered method were compared with similar calculations using the Successive Substitution method. A low error of the method of Quasi-Newton Successive Substitution was obtained when calculating phase equilibrium with a capillary pressure jump.
