“…However, Savile and Lalonde discovered that the organic carbonic anhydrases are not well suited for harsh process environments. There are other methods for CO 2 capture process such as chilled ammonia process (CAP), amino acid salt, biphasic solvents, phase change solvents, and ionic liquids . However, these processes require extensive research and developments in order to generate a reliable database and optimize the processes …”

The CO2 desorption analyses of several amines were performed to reveal the behaviour of the amine regeneration process. A typical primary amine (MEA) and two other secondary amines (MMEA and DEA) were selected, in preparation for amine solutions under different concentrations, from 1–7 mol/L. The regeneration curves were generated and plotted to describe the process. It was discovered that the specific CO2 loadings (mol/mol) that distinguish the amine regeneration curves into different regions were the same for the specific amine, despite different concentrations. These points were defined as “turning points” on regeneration curves. The turning points of MEA, MMEA, and DEA are located at CO2 loadings of 0.40 mol/mol, 0.38 mol/mol, and 0.28 mol/mol, respectively. The carbamate stabilities of the three amines were compared with each other based on the slope of regeneration curves at slow region. The amine regeneration tests compared the relative heat duty at the first 2 h: MMEA > MEA > > DEA, which is the same order as carbamate stability.

Abstract. The CO 2 desorption analyses of amines were performed to reveal the behaviour of amine regeneration process. A typical primary amine (MEA) and two other secondary amines (MMEA and DEA) were selected in preparation for amine solutions under different concentrations, from 1-7 mol/L. The regeneration curves were plotted to describe the process. It was discovered that the specific CO 2 loading (mol/mol) that distinguish the amine regeneration curves into different regions were the same for the specific amine, despite different concentrations. These points were defined as "turning points" on regeneration curves. The turning points of MEA, MMEA and DEA are located at CO 2 loading of 0.40 mol/mol, 0.38 mol/mol and 0.28 mol/mol, respectively. The regeneration tests compared the relative heat duty at the first 2 hours: MMEA > MEA > > DEA.

Modeling of circulating fluidized beds systems for post‐combustion CO₂ capture via temperature swing adsorption

et al. 2017

The technology of circulating fluidized beds (CFBs) is applied to temperature swing adsorption (TSA) processes for post-combustion CO 2 capture employing a commercial zeolite sorbent. Steady state operation is simulated through a one-dimensional model, which combines binary adsorption with the CFB dynamics. Both single step and multi-step arrangements are investigated. Extensive sensitivity analyses are performed varying the operating conditions, in order to assess the influence of the main operational parameters. The results reveal a neat superiority of multi-step configurations over the standard one, in terms of both separation performance and efficiency. Compared to fixed-bed TSA systems, CFB TSA features a high compactness degree. However, product purity levels are limited compared to the best performing fixed-bed processes, and heat management within the system appears to be a major issue. As regards energy efficiency, CFB systems place themselves in between the most established absorption-based technologies and the fixedbed TSA.
