• 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 ...

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...

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 [...]

Abstract: The use of mixed amine system in gas treating processes is increasing today. For natural gas sweetening purposes, mixed amines are typically mixtures of MDEA and DEA or MEA that enhance CO2 removal while retaining desirable characteristics of MDEA such as reduced corrosion problems and low heats of reaction. In this work, a process simulator was used to predict the performance of an I...

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...
