What causes an increase in water content within the system? Answer: ① The methanol-water separation tower is not well controlled, resulting in an excessively high top temperature and a low amount of methanol returning to the tower. ②Due to issues with the conversion system, the temperature of the conversion gas is too high or the ammonia scrubber contains water. ③There is a leak in the reboiler of the regeneration tower or in the methanol reflux cooler at the top of the regeneration tower.

Answer: 1. The methanol-water separation tower is not well controlled, resulting in an excessively high top temperature and a low amount of methanol returning to the tower. 2. Reasons related to the conversion system: excessive temperature of the conversion gas or water in the ammonia scrubber. 3. Leakage in the reboiler of the regeneration tower or the reflux methanol cooler at the top of the regeneration tower.
