The knowledge of vapour-liquid equilibrium (VLE) the carbon dioxide-alkanolamine-water system at high pressure plays a critical role in design natural gas sweetening systems. Semi-empirical thermodynamic models have been widely used to estimate VLE pressure. However, understanding their correlation behaviour is limited. Therefore, this study reviews chronological development and analyse perform...

Hydrogen sulfide is essentially removed from the raw natural gas to meet process, health, safety and environmental standards. Alkanolamine based absorption process remains prevalent technique for hydrogen removal due ease of operation economic considerations. The design such separation systems a critical factor in meeting stringent requirements optimizing operations. To achieve precise design, ...

A significant effort is under way to identify improved solvents for carbon dioxide (CO 2 ) capture by chemisorption. We develop a predictive framework that applicable aqueous solvent + CO mixtures containing cyclic amines, alkyl polyamines and alkanolamines. number of the studied exhibit liquid-liquid phase separation, behaviour has shown promise in reducing energetic cost capture. The proposed...

Abstract. The carbon capture, use, and sequestration (CCUS) techniques are proven to be efficient at lowering the atmospheric concentration of dioxide. Notwithstanding advances in this area, there still significant restrictions dioxide (CO2) capture industry such as high capital costs, solvent evaporation losses, low absorption desorption rates. Ionic liquids (ILs) have received much interest g...
