Axens technology selected for two new gas treatment plants in Kuwait

Hydrocarbon Engineering,

Axens is supplying process design packages for the gas treatment of two gas plants located in North Kuwait, whose EPC is managed respectively by SPETCO and Jereh. Axens will licenses two HySWEETTM units for acid gas removal, as well as two Smartsulf® units for sulfur recovery, and two TEG units for gas drying.

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

Each HySWEET unit will treat 163.4 million ft3/d 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 commercialised 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 the maximisation of mercaptans removal along with the absorption of the acidic species, while minimising the usual drawback of hybrid solvents such as an increased hydrocarbon co-absorption that is 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.
