    摘要: A process for separating components of gas mixtures which have different hydrate forming characteristics which uses an aqueous liquid to absorb one of the gases preferentially by attaining conditions slightly above the catastrophic point at which gas hydrates form. Specifically, the separation of gas mixtures containing light hydrocarbons and carbon dioxide is accomplished without significantly reducing the pressure of the carbon dioxide or without requiring significant amounts of heat energy for regeneration.
