Abstract
The raw natural gas is deacidized and dehydrated in units DA and DH. The treated gas is then purified by adsorption of the mercaptans in first enclosure A. Part of the purified gas is heated in E, then fed into second enclosure Aso as to discharge the water adsorbed by the adsorbent material contained in this second enclosure. A water-laden purge gas is fed into third enclosure Acontaining a mercaptan-laden adsorbent material. In A, the mercaptans are desorbed and replaced by the water. The gas from the third enclosure is washed in unit L, then recycled.
