Temperatures are relatively low in winter and spring – the temperature in the absorption tower is 26 degrees, and the temperature of the rich gas is also 26 degrees. I have set the pressure at 1.0 MPA, and the volume of the absorbent used is 24 cubic meters. Everyone, please share what pressure and absorbent levels are appropriate!
Essentially, high pressure and low temperature are utilized for absorption, while low pressure and high temperature are utilized for desorption. The terms high pressure, low pressure, low temperature, and high temperature mentioned here are relative and depend on your specific process and actual conditions. If you don’t want to do the calculations, you can gradually find the optimal pressure and amount of absorbent. By keeping all other variables constant and adjusting just one variable, you can determine the advantages of such an approach
