Why is methanol extracted from the middle of the CO2 absorption tower, cooled, and then returned to the tower? Answer: Since the temperature rises during the absorption process of methanol, this reduces its absorption rate; therefore, in the CO2 absorption tower, methanol is drawn out, cooled in an ammonia cooler, and then returned to the tower.

Lower the temperature to improve absorption efficiency.

Since the temperature of methanol rises after absorbing CO2, which affects the absorption process, it is necessary to extract it, cool it down, and then return it to the tower.

Due to the exothermic absorption process, the temperature of methanol increases after CO2 absorption, which reduces its absorption capacity; therefore, it is necessary to extract the methanol from the tower, cool it, and then feed it back into the absorption tower.

At the same pressure, the lower the temperature, the higher the absorption efficiency.
