H 2 S‐hydrate formation is demonstrated as a method for cleaning contaminated natural gas. Not only the final equilibrium cleanup but also the rates of separation attainment are much higher than for CO 2 hydrates. H 2 S concentrates in the hydrate phase and is then depleted from the gas; this was observed at temperatures as high as 15 °C. The shortest batch‐formation times are on the order of 1 min at pressures of approximately 30 bar. Formation times of H 2 S hydrates are considerably shorter than for CO 2 . The supersaturation and mixing speed are the critical parameters as well as maintaining maximum solvation of H 2 S in water throughout the process.
