การดูดซึมด้วยสารเคมีโดยใช้สารละลายเ

Chemical absorption using amine solutions is widely used because of its low cost. The solution used can be reused. It has high carbon dioxide capture efficiency and is thermally stable. It is an exothermic reaction and is reversible. Higher temperature will lead to more reversibility of the reaction. Therefore, in a system with a high temperature it will cause The lower efficiency of carbon dioxide absorption by the amine solution samples commonly used in this process was solved. monoethanolamine (MEA), diethanolamine (DMA), methyl diglycolamine (DGA), etc. Mechanism of carbon dioxide absorption by monoethanolamine. (monoethanolamine) has a Zwitterion reaction (Zwitterion) as the main reaction. It is divided into 2 parts, which is the creation of a zwitterionic molecule. One molecule of carbon dioxide reacts with one molecule of monoethanolamine. Forms a zwitterionic molecule as shown in Equation 5. For the absorption of carbon dioxide by monoethanolamine solution, MEAH+ CO- is called “carbamate”, then car One molecule of bamate reacts with another molecule of monoethanolamine. in order to transfer protons as in equation 6

The chemical absorption of amine solutions is widely used due to their low cost price. The solution used can be reused, with high carbon dioxide capture efficiency and good thermal stability. It is an exothermic reaction and a reversible reaction, and an increase in temperature will lead to more reaction reversals. Therefore, in high-temperature systems The low carbon dioxide absorption efficiency of commonly used amine solution samples in this process solves the problem of monoethanolamine (MEA), Diethanolamine (DMA), methyldiethanolamine (DGA), etc.<br>The carbon dioxide absorption mechanism of monoethanolamine is mainly Zwitterion reaction. It is divided into two parts: molecular exchange ions. A carbon dioxide reacts with a monoethanolamine. The formation of Twitter ion molecules, as shown in equation 5, is called MEAH+for the absorption of carbon dioxide using a monoethanolamine solution. CO - "Carbamate"

The chemical absorption of amine solution is exothermic and reversible because of its low cost, reusability, high carbon capture efficiency and good thermal stability. The higher the temperature, the greater the reversal of the reaction. Therefore, in the high temperature system, the lower carbon dioxide absorption efficiency will make the amine solution samples commonly used in this process dissolve monoethanolamine (MEA), diethanolamine (DMA) and methane.<br>The mechanism of absorption of carbon dioxide by monoethanolamine takes Zwitterion as the main reaction, which is divided into two parts: one is that carbon dioxide generates ion exchanger molecules, the other is that it reacts with monoethanolamine, and the equation is 5. For monoethanolamine solution to absorb carbon dioxide, it is called MEAH+CO- that is, "carbonate".<br>Then, one methyl carbonate molecule reacts with another monoethanolamine molecule to form proton transfer, as shown in Equation 6.
