In this study, plantwide control of an absorption/stripping CO2 capture process using mono-ethanol-amine was investigated using dynamic simulation. In this system, CO2 removal ratio is influenced by operating variables such as lean solvent rate and lean solvent loading, which is in-turn determined by reboiler duty in the stripper. Moreover, we found that the long term stability of the system ca...

Many efforts have been made to develop amine-based solid adsorbents for capture of CO2 by adsorption. Compared with the traditional process of absorption in aqueous solutions of amines, the adsorbents with amine immobilized in solids generally result in processes with lower capital and energy costs. The literature contains some experimental studies of CO2 adsorption in impregnated materials; ho...

A classical force field approach was used to characterize the solvation dynamics of high-density CO₂(g) by monoethanolamine (MEA) at the air-liquid interface. Intra- and intermolecular CO₂ and MEA potentials were parameterized according to the energetics calculated at the MP2 and BLYP-D2 levels of theory. The thermodynamic properties of CO₂ and MEA, such as heat capacity and melting point, were...

The absorber is the key unit in post-combustion monoethanolamine (MEA)-based carbon dioxide (CO2) capture process. A rate-based dynamic model for developed and validated using steady-state experimental data reported open literature. Sensitivity analysis performed with respect to important parameters associated reaction, mass transport physical property relationships. Then, a singular...

The corrosion behavior of two stainless steels (316L and 304L) was evaluated using a CO2-loaded aqueous solution 30 wt.% monoethanolamine (MEA) with view to simulating related mechanisms in amine treatment procedures. Corrosion experimentally as function CO2 loading temperature, electrochemical techniques (polarization curves, cyclic polarization, EIS measurement). results reveal that the MEA c...

Acid Orange 7 (AO7) is one of the most common azo dyes; however, its strong bond makes them difficult to biologically degrade. We sought degrade AO7 dye using CeO2 as a promising alternative photocatalyst. powders were synthesized with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) precipitant by solvothermal process combined calcination in air. Compared oxygen storage ...
