Question: What is the effect of operating temperature on the absorption process? Answer: Under certain pressure and initial gas composition, the lower the temperature, the greater the solvent’s ability to absorb solutes; the higher the temperature, the weaker this ability. Therefore, a lower temperature is required for the solvent to be absorbed into the tower, but the solvent temperature cannot be too low either, as extremely low temperatures increase the viscosity of the solvent and reduce its absorption efficiency.
At a certain pressure and initial gas composition, an increase in temperature leads to an increased amount of absorbent oil used, and it also increases the C1 and C2 contents in the recovered mixture. This reduces the absorption efficiency and increases the desorption load. Therefore, low temperatures are favorable for the absorption process. However, too low a temperature will increase the viscosity of the absorbent and also reduce its absorption efficiency.

:At constant pressure and with unchanged compositions of the absorbent and the gas, an increase in temperature reduces the solubility of the target gas in the absorbent
