✦ Synopsis

To reduce the risk of hydrate formation, methanol is the most commonly used inhibitor. A modified Peng-Robinson (PR) model based on Mollerup's random-nonrandom (RNR) theory was developed to describe the vapor-liquid equilibria of strongly polar methanol-water-gas systems under pressure. The new model (PR-RNR model), as coupled with the simplified version of the Holder-John three-shell hydrate equilibrium model proposed by the authors, has been successfully used to predict the effect of methanol concentration on hydrate formation of pure gases and gas mixtures.
