What factors can cause an increase in the 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.
①The methanol-water separation tower is not well controlled, resulting in an excessively high top temperature and a low amount of methanol reflux. 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.

①The methanol-water separation tower is not well controlled; the tower temperature is too high and the amount of methanol returning is low. 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.
