The topic of global warming as a result of increased atomospheric CO2 concentration is becoming the most important environmental issue that the world faces today.[1] The capture and separation of CO2, especially CO2 from large point source, for example, fossil-fuel-fired electrical power–generation plants is critical to stabilize the atomospheric CO2 concentration.[2] The existing commercial CO...

Accurate modeling of thermodynamic properties for CO2 absorption in aqueous alkanolamine solutions is essential for the simulation and design of such CO2 capture processes. In this study, we use the Electrolyte Nonrandom Two-Liquid activity coefficient model to develop a rigorous and thermodynamically consistent representation for the MDEA-H2O-CO2 system. The vapor-liquid equilibrium (VLE), hea...

Effects of alkanolamine molecules on the corrosion inhibition L80–1Cr steel were studied in a CO2-saturated 1 wt% NaCl solution at well downhole temperatures 20 and 80 °C. The electrochemical results showed lower rates °C, for which more influenced by injection. experimental molecular modelling calculations using DFT revealed that adsorption/desorption played determining role kinetics character...

There are a lot of research programs focusing on the development new solvents for carbon dioxide capture. The most important priority should be reducing energy consumption needed at regeneration step, but minimizing solvent degradation and its corrosivity is also considered as priority. In this research, aqueous blends 2-amino-2-methyl-1-propanol (AMP: 1 kmol·m−3) 1-amino-2-propanol (MIPA: 0.1–...
