Membrane gas separation for carbon capture has traditionally been focused on high pressure applications, such as pre-combustion capture and natural gas sweetening. Recently a membrane-cryogenic combined process has been shown to be cost competitive for post-combustion capture from coal fired power stations. Here, the membrane-cryogenic combined process is investigated for application to post-co...

This paper includes the significant on-site experience of the authors related to problems faced in amine systems with fresh amine and their possible solutions in phases#2&3 of South Pars gas                complex. The amine system was designed as a closed circuit system with the primary objective of removing H2S, CO2, and other acidic components from gaseous hydrocarbon streams. Amine plant op...

The sour gas sweetening is one of the main processes in industries. Gas done through chemical processes. Therefore, it requires high cost and energy. results show that increasing operating temperature increases mass transfer coefficient rate. Theoretical experimental data sulfur removal 4.5 W magnetic field desirable. increase percentage 6.75 about 16.4% 15.2%, respectively. According to obtain...

Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...

Developing cold sweetening resistant processing varieties is one of the frontal areas of research all over the world. In India, first potato processing variety was released in the year 1998 and till 2005 three varieties have been developed. But, there is no information available regarding sugar accumulation response of Indian varieties to low temperature storage. Therefore, it is imperative to ...

Membranes are attractive for upgrading natural gas; however, the gas permeation processes through membranes challenging to control. The coexistence of condensable H2S and CO2 typically causes membrane performance decline under practical feed conditions, due uncontrolled penetrant competition undesired plasticization polymer matrix. In this paper, we report a strategy successfully transform thes...
