Method of purifying a natural gas by mercaptan adsorption

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 1 . Part of the purified gas is heated in E 1 , then fed into second enclosure A 2 so as to discharge the water adsorbed by the adsorbent materia...

Beschreibung
Zusammenfassung:	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 1 . Part of the purified gas is heated in E 1 , then fed into second enclosure A 2 so 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 A 3 containing a mercaptan-laden adsorbent material. In A 3 , the mercaptans are desorbed and replaced by the water. The gas from the third enclosure is washed in unit L, then recycled.
