Process for the reduction/removal of the concentration of hydrogen sulfide contained in natural gas

A process for the removal of hydrogen sulfide from natural gas, comprising:

• feeding a natural gas stream and a water stream to a reaction vessel to form a gaseous composition consisting of the natural gas and the water in the reaction vessel;
• treating the gaseous composition inside the reaction vessel at a temperature of from 15 to 25° C. at a pressure of from 5 to 15 MPa to form a solid H2S hydrate, wherein the gaseous composition comprises water in an amount of 40-80% by weight based on the total weight of the composition;
• separating the solid H2S hydrates from the reaction vessel;
• and
• at least one of (i) injecting the H2S hydrates into a geologic formation and (ii) liquefying the solid H2S hydrates,
• wherein the natural gas remains gaseous during the feeding and the treating.
