摘要: Abstract MHV2 is a group-contribution equation-of-state based on the modified Huron-Vidal mixing rule. It combines SRK with model for excess Gibbs energy, UNIFAC model. can be applied at all temperatures and pressures of interest in chemical process design it capable reproducing low pressure information given by In present work, we have investigated ability to predict high vapor-liquid equilibria (VLE), liquid-liquid (LLE), three-phase systems mixed solvents together supercritical gases lighter alkanes. Considering complexity these mixtures, satisfactory results are obtained.
