<p>PROBLEM TO BE SOLVED: To provide a method for separating gas components using hydrate promoter. SOLUTION: The method for separating gas components according to this invention comprises a step of producing gas hydrates concentrated with components having relatively higher forming ability of gas hydrates among a mixed gas by reacting a solution containing a hydrate promoter with the mixed gas, and a step of dissociating a specified gas component from the produced gas hydrates, wherein the hydrate promoter is selected from the group consisting of acetone, propylene oxide, 1,4-dioxane, and tetrahydrofuran, and the hydrate promoter is contained in the solution at a ratio of 0.5 to 6.0 mol%, and the production of gas hydrates is conducted at a temperature of 272 to 303 K and under a pressure of 1 to 60 bar.</p> |
