Reaction Mechanism and Kinetics of Aqueous Solutions of 2-Amino -2 Methyl-1,3- Propanediol and Carbonyl Sulphide
Aqueous solutions of amines are often used to remove CO2, H2S and COS from a large number of industrial gas streams. There are several different processes, each suiting a certain application. A recent advance in gas treating technology is the application of sterically hindered amines, which offer capacity advantages for CO2 over commercial amines such as monoethanolamine (MEA) (Sartori and Sava...
متن کاملMass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution
In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...
متن کاملSemicontinuum Solvation Modeling Improves Predictions of Carbamate Stability in the CO2 + Aqueous Amine Reaction.
Quantum chemistry computations with a semicontinuum (cluster + continuum) solvation model have been used to cure long-standing misprediction of aqueous carbamate anion energies in the industrially important CO2 + aqueous amine reaction. Previous errors of over 10 kcal mol(-1) are revealed. Activation energies were also estimated with semicontinuum modeling, and a refined discussion of the compe...
متن کاملA means to an interface: investigating monoethanolamine behavior at an aqueous surface.
The use of amine scrubbers to trap carbon dioxide from flue gas streams is one of the most promising avenues for atmospheric carbon dioxide reduction. However, modifications are necessary to efficiently scale these scrubbers for use in fossil fuel plants. Current advances in tailoring amines for CO2 capture involve improvements of bulk kinetic and thermodynamic parameters, with little considera...
متن کاملCalorimetric Measurements of CO2 Absorption into Aqueous -Methyldiethanolamine Solutions
A reaction calorimeter was used to study the rate and heat effects during CO2 absorption into aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were carried out at constant pressure of 0.1 MPa and 0.3 MPa over a range of temperature from 293 K to 333 K. The amine content changed from 10 to 30 mass %. The experimental equipment and procedure were described with the emphasis on ...
