Hydrate Prediction using Vapor-Solid Equilibrium Constant

In previous post, hydrate in natural gas system can be estimated by two approaches, which are approximate method and analytical method. Approximate method used when gas composition is unknown. It uses pressure-temperature correlation to predict hydrate formation temperature.

In this post, I want to share how to predict hydrate formation using analytical method, which uses vapor-solid equilibrium constant. Vapor-solid equilibrium constant is expressed as below:
