Purification of gases from aggressive components during transportation

The problems connected with extraction of hydrogen disulfide from the hydrogen containing gas circulating within the diesel fuel hydrotreating unit, as well as from the dry gas produced on the catalyst cracker have been examined. The availability of hydrogen disulfide in the above gases causes corrosion of equipment and pipelines on the one hand and leads to environment pollution and catalyst poisoning on the other hand. To remove hydrogen desulphide from the hydrogen containing gas and the dry gas an absorption treatment method using 15% aqueous monoethanolamine solution as an absorbent has been proposed.
