Abstract
Process for the removal/reduction of the hydrogen sulfide contained in natural gas which comprises: a) feeding natural gas and water to a reaction vessel maintained under thermodynamic conditions favorable for the formation of HS hydrates and substantially at the production pressure of natural gas; b) discharging the HS hydrates, from the bottom of the reaction vessel; c) optionally melting the hydrates and re-injecting water and/or gas comprising hydrogen sulfide and/or the hydrates as such into the same production field or into a geologically equivalent structure; and d) optionally feeding the remaining natural gas to a conventional softening process.
