Problems with methanol distillation
Thread Content
During production, the moisture content of the pure methanol product obtained is above the specified limit; how should this be adjusted? Could that expert please provide a detailed explanation?
Common adjustment methods include increasing the top pressure, raising the reflux ratio, and lowering the top temperature
The reason for the excessive moisture content in the recovered pure methanol is A: the reflux ratio is too low, causing the heavier components to rise； B. Excessive steam consumption, resulting in too high a temperature at the bottom of the tower ； The adjustment method adopted is A: increase the reflux ratio and reduce the recovery rate ； B. Reduce steam consumption and lower the bottom temperature of the tower
