Abstract
This application is in the field of technologies for desulfurization and demercaptanization of raw gaseous hydrocarbons (including natural gas, tail gas, technological gas, etc, including gaseous media). It can be used for simultaneous dehydration and desulfurization/demercaptanization of any kind of raw gaseous hydrocarbons.
Claims8
A process of desulfurization and/or demercaptanization and/or dehydration of gaseous hydrocarbons, comprising:
- mixing one or more gaseous hydrocarbons to be purified with an oxygen-containing gas,
- pressurizing and passing through a reactor loaded with a solution of a catalyst for oxidating hydrogen sulfide and mercaptans in an absorbent that provides dehydration of said gaseous hydrocarbons,
- and maintaining a gas pressure, as determined by a desired content of water in purified gas,
- wherein the catalyst comprises mixed-ligand complexes of transition metals, and
- wherein a conversion rate of hydrogen sulfide and mercaptans into sulfur and disulfides is at least 99.99%.
