Abstract

A new numerical approach is developed for vapor solid equilibrium calculations and predicting vapor solid equilibrium constant and composition of vapor and solid phases in gas hydrate formation. Equation of state methods generally do a good job of determining vapor phase properties but solid phase is much more difficult and inaccurate. This proposed new model calculates vapor solid equilibrium constant and vapor and solid phase composition as a function of temperature and partial pressure. This new numerical model also has an advantage to tune coefficients to cover different sets of experimental data accurately .
