摘要
Method for removing the mercaptans contained in a gas, in which: a) the gas is circulated through an acidic adsorbent solid SA1 in such a way as to adsorb a part of the mercaptans contained in the gas and to obtain a mercaptan-loaded acidic adsorbent solid and a mercaptan-depleted gas (4), b) a liquid (9) containing olefins is circulated through said mercaptan-loaded acidic adsorbent solid SA3 in such a way that the mercaptans react with the olefins so as to form sulfides, and then c) a flushing gas (15) is passed through the acidic adsorbent solid SA2 in such a way as to expel an effluent comprising a portion of said liquid.
