Why must the temperature of the material entering the methanol separator be kept below 40°C? Answer: The gas exiting the tower after being cooled by the water cooler has most of its methanol and water condensed into liquids, which then enter a separator to separate out crude methanol. If the temperature of the gas entering the separator increases, the amount of methanol vapor rises; when this gas is sent to the synthesis tower under pressure, it affects the quality of the methanol produced. The temperature entering the separator is affected by the water supply volume, water supply temperature, and circulation rate. As the temperature rises, it is necessary to increase the flow rate of cooling water appropriately, lower the temperature of this water, or reduce the circulation volume, in order to keep the temperature of the gas entering the separator below 40°C and thus minimize the amount of methanol vapor carried away.

The gas exiting the tower after being cooled by the water cooler has most of its methanol and water condensed into liquids; this gas then enters a separator where crude methanol is separated out. The effective gas resulting from this process contains approximately 0.611% methanol vapor. If the temperature of the gas entering the separator increases, the concentration of methanol vapor rises, and this will affect the quality of the methanol produced when the gas is sent to the synthesis tower under pressure. The temperature entering the separator is affected by the volume of water in the circulation flow, the temperature of the incoming water, and the circulation rate. As the temperature rises, it is necessary to increase the amount of cooling water supplied, lower the temperature of this water, or reduce its flow rate, in order to keep the temperature entering the separator below 40°C and thereby reduce the amount of methanol vapor carried away.
