Gas sweetening using amines is an important gas treatment process. Existing gas sweetening units may be revamped to achieve a variety of aims, for example to expand processing capacity, to reduce operating costs, to accommodate a different feed, to reduce emissions levels, etc. Current practice for retrofit design is to use engineering judgement and experience and simulation studies to identify...

Gas sweetening, the removal of acid gases (H2S and CO2) by absorption in aqueous alkanolamine solutions, is an important gas treatment operation. Methyldiethanolamine (MDEA) is widely employed for gas sweetening, because of its high absorption capacity and flexibility to meet process requirements. For process simulation or design, realistic predictions of acid gas solubilities in MDEA solutions...

• phenomena-based process intensification approach to generate sustainable separation of sour gases from offshore natural gas is proposed. All possible alternatives using a bottom-up are explored systematically. Six intensified identified as novel and innovative candidates worthy potential industrial application. Offshore represents significant portion global reserves. Processing essential for ...

As oil and gas reserves become depleted, producers are increasingly driven to process difficult or unconventional petrochemical fuel sources to sell to the market in order to meet rising demand. One such source is the production of sour gas wells that contain high levels of mercaptan (thiol) species. In sour gas processing applications, a waste acid gas stream (ie. a stream containing high conc...

Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]
