- Abstract
This paper examines the separation of gas mixtures based on nitrogen trifluoride and carbon tetrafluoride by different versions of gas hydrate crystallization. We calculate the distribution coefficient and separation factor of the major components of the mixture in the temperature range 253-273 K for different pressures and gas mixture compositions. The results demonstrate that gas hydrate crystallization ensures efficient separation of mixtures containing nitrogen trifluoride and carbon tetrafluoride. Directional crystallization allows nitrogen trifluoride to be separated more completely, whereas crystallization at constant pressure ensures a larger yield of the purified material.
