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 mode

Abstract
The experimental work reported here gives hydrate forming conditions in the water liquidβhydrocarbon liquidβhydrate region for five mixtures of methane and nβbutane. Data available in the literature were used to establish the parameters in a computer program for predicting hydrate forming conditions in condensed systems. The method is shown to be reliable for several systems of widely variable composition.

A predictive model to describe the thermodynamics of clathrate hydrate formation in anionic surfactant based w/o microemulsions is developed. The process of controlled hydrate formation leads to an in-situ manipulation of droplet size by crystallizing out part of the microaqueous phase. The feasibil
## Coupled reaction4iffusion equations are known to exhibit a wealth of multiple coexisting stationary solution patterns as the characteristic length of the system grows. We describe and implement a technique which allows us. by studymg only stationary solution branches at small system lengths, to
