Axens HySWEET™ technology selected for two new Gas treatment plants in Kuwait

Axens is supplying the process design packages for the gas treatment of two Gas Plants located in North Kuwait, which EPC are managed respectively by SPETCO and Jereh. Axens licenses two HySWEET™ units for the acid gas removal, as well as two Smartsulf® units for the sulphur recovery and two TEG units for gas drying.  

The units for both gas plants are now under process design phase and the plants will be commissioned in early 2024.

Each HySWEET™ unit will treat 163.4 MMSCFD of gas to remove the acid gases including H2S, CO2, COS and mercaptans to meet sales gas specifications.

HySWEET™ is a hybrid process for simultaneous removal of mercaptans and acid gases from natural gas, developed by TotalEnergies and commercialized by Axens. It is based on the selection of the most suitable nonproprietary physical solvent for blending a variety of commercial amines (DEA, MDEA, formulated MDEA). It enables to maximize mercaptans removal along with the absorption of the acidic species while minimizing the usual drawback of hybrid solvents like an increased hydrocarbon (HC) co-absorption potentially harmful for the downstream Sufur Recovery unit treating the recovered acid gas stream. An additional benefit of this hybrid formulation is a lower regeneration duty reducing OPEX and carbon intensity.

HySWEET™ features less than 1%vol hydrocarbon in acid gas as well as up to 15% savings on reboiling duty.
