Abstract

The separation of gas mixtures based on noble gases by means of gas hydrate crystallization is considered for various schemes of the process. The separation coefficient and the separation factor of the basic mixture components at 273 K and at different pressures and compositions of the gas mixture are calculated. It is shown that xenon can be almost completely separated from a mixture in two stages of gas hydrate crystallization even without the use of booster gases. Directional crystallization allows us to separate xenon more completely and crystallization at constant pressure enables us to obtain a more highly purified product.
