| titleOfInvention | Cryogenic method for simultaneous selective desulphuration and stripping of a gas mixture consisting mainly of methane and containing also h2s and c2-hydrocarbons and more |
| abstract | After debenzolization (25) and refrigeration (2) producing condensates (4), a gas mixture (1) is washed between 0°C and -45°C by means of a solvent (5) selective of HSS to produce a methane stream (64) of which the H2S partial pressure is lower than 65 Pa and a liquid phase (9a) rich in H2S and containing at least 80 % molar of C3-hydrocarbons in C3 and more of the gas mixture (1). The liquid phase (9a) is subjected to a demethanization process (29, 9) producing a rich demethanized solvent (11) and a gas phase rich in methane (10), then the solvent (11) is sufficiently cooled between -45°C and -80°C to cause its demixtion into a lower liquid fraction (38) which contains H2S and, in methane equivalent less than 5 % molar of hydrocarbons, and into an upper liquid fraction (37) formed of the C3-hydrocarbons in C3 and more. Said fractions (37, 38) are separated and the fraction (38) is regenerated (46, 16, 20) to produce a stream (24) of acid gas enriched with H2S and containing the above-mentioned low contents of hydrocarbons and a regenerated solvent (21). |
