In this work, the absorption–desorption performance of CO2 in six new solvent blends amine (diisopropylamine (DPA), 2-amino-2-methyl-1-propanol (AMP), methyldiethanolamine (MDEA), diethanolamine (DEA), diisopropanolamine (DIPA), and ethanolamine (MEA)), sulfolane, methanol has been monitored using ATR-FTIR spectroscopy. Additionally, NMR-based species confirmation viscosity analysis were done f...

In order to reduce global CO2 emissions, capture based on absorption in an amine/water mixture is established method. To develop such processes, correct physicochemical properties like densities and viscosities are important.The first objective of this work explore mathematical correlations for fitting viscosity data aqueous Monoethanolamine (MEA) Methyldiethanolamine (MDEA). A second evaluate ...

In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...

Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...

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...

in order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. the purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity. second order chemical reaction for two different cases (fast and slow) were considered. the system partial differential equations obtained was...
