Why is methanol extracted in 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.

Since the temperature rises during the absorption process of methanol, which in turn reduces its absorption rate, methanol is drawn out at the middle section of the CO2 absorption tower, cooled in an ammonia cooler, and then returned to the tower

Since the temperature rises during the absorption process of methanol, this increase reduces the absorption rate of methanol; therefore, in the CO2 absorption tower, part of the methanol is drawn out, cooled in an ammonia cooler, and then returned to the tower.
