Natural gas hydrate is a solid crystalline compound formed from the composition of water and gas and is part of the clathrate family. Gas hydrate can be formed by pure gas or a gas mixture consisting of two or more components. Gas hydrates are recognized as non-stoichiometric solids. One of the methods or methods that has been most successful in predicting or recognizing hydrate phases in hydrocarbon equilibrium is based on the relative Kvs size of the vapor-solid equilibrium constant. Tables of equilibrium for species or constituents of hydrates known as normal butane are listed in various articles and books. With the discovery of the heaviest constituents of hydrates, their equilibrium constants need to be more accurately predicted in the un-hydrated phase of the hydrocarbon mixtures, especially in the reservoir fluids.
