摘要： A regenerative process is provided for removing mercaptans contained in a gas by means of an absorbing agent based on at least one metal oxide capable of chemically fixing the mercaptans. The process comprises an absorption step to fix the mercaptans on the absorbing agent and a regeneration step for regenerating the absorbing agent laden with sulphur-containing products resulting from said fixation. The regeneration is carried out by sweeping the absorbing agent with a hot inert gas to bring the absorbing agent to a temperature between 250.degree. and 500.degree. C. and desorb the sulfur-containing products, and by contacting the absorbing agent thus treated with a gas containing free oxygen to reoxidize the absorbing agent and by cooling the reoxidized absorbing agent by sweeping with a cold inert gas.

摘要： Method and devices for the selective removal of H.sub.2 S from an H.sub.2 S-containing gas by contacting the gas in an absorption column with an H.sub.2 S-selective absorbent liquid and transferring the H.sub.2 S-charged absorbent liquid to the upper part of a second column. The charged absorbent liquid then travels to a regeneration zone at the bottom of the column, where it is heated to a temperature at which the absorbent liquid is vaporized and the H.sub.2 S is released.The regeneration zone temperature causes the absorbent liquid vapor to strip the H.sub.2 S back to the upper part of the column where it forms an equilibrium with the H.sub.2 S-charged absorbent liquid at a temperature not more than 30.degree. C. higher than the injection temperature of the absorbent liquid in the absorption column, which equilibrium temperature is maintained by the temperature in the regeneration zone. The H.sub.2 S-enriched vapor formed at the equilibrium point is then tapped.

摘要： Process for removing hydrogen sulfide at low concentration in a gas containing water vapor. The gas is cooled to a temperature below the dew point of water, which condenses and separates the water. The dry gas is scrubbed free of hydrogen sulfide by an H.sub.2 S-absorbent solvent forming a purified gas. The purified gas is contacted and rehydrated with heated water so that the water content as water vapor corresponds to a mass flow rate of water substantially equal to the mass flow rate of the water present in the H.sub.2 S-containing gas before cooling. The condensed water circulates in a closed circuit to contact and rehydrate the purified gas, and then is cooled to the appropriate temperature for cooling the H.sub.2 S-containing gas. An apparatus, appropriate for carrying out the process is disclosed.
