Abstract: The invention provides a method and system for separating xenon-krypton mixed gas by hydrate formation process. The system is mainly composed of a gas hydrate generating unit, a heat exchanging unit and a gas-water separating unit: pre-cooled xenon-krypton mixed gas is injected from a bottom of a reaction tower, xenon gas in the mixed gas and water attached to a porous tray generate a xenon gas hydrate; and water is injected from a top of the tower to wet the porous tray, a generated hydrate particle is washed and collected to the bottom of the tower simultaneously to form a hydrate slurry, after passing through the heat exchanging unit, the xenon gas hydrate in the slurry is decomposed to form a gas phase flow and a water phase flow, and then enters the gas-water separating unit, and the xenon gas is separated from decomposed water.
