Where is the sensitivity point of the water separation tower in low-temperature methanol washing? What are the phenomena at high and low levels?
This is mainly reflected in temperature; the operation of the methanol water tower, under certain pressures, can have its operating condition determined primarily through temperature and pressure differences. When the ratio of methanol to water in the feed is incorrect, if the temperature of the methanol vapor at the top of the tower increases, the water content at the top of the tower rises; in such cases, it is necessary to increase the reflux rate or reduce the amount of water in the feed ； When the temperature at the bottom of the tower is low, the alcohol content in the wastewater increases; in such cases, the amount of water entering the system should be increased
