Modeling of xenon gas hydrate distribution coefficient at methane-containing mixtures separation

The aim of this study is to theoretically estimate of xenon (Xe) gas hydrate distribution coefficient. For the first time, the effect of various natural gas compositions on the Xe gas hydrate distribution coefficient has been investigated at the gas hydrate dissociation pressures, 4.00 and 8.00 MPa in the temperature range 273.15-283.15 K. Based on the results obtained, it can be concluded that Xe concentration in the gas hydrate phase is efficient at the minimum C3H8 concentration in a multicomponent gas mixture close to natural gas composition, at temperature and pressure conditions equal to 273.15 K and 8.00 MPa.
