What precautions should be taken during the maintenance of the methanol washing unit? Answer: When opening the interior of the tower, it is necessary to prevent the combustion and explosion of sulfides as well as corrosion within the system. It is generally required to isolate air as much as possible and prevent air convection ； At the same time, the tower needs to be flushed with water to displace methanol; the system must be cleaned thoroughly before maintenance can be carried out.

1. Methanol must be thoroughly flushed and replaced before the manhole can be opened for maintenance； 2. It is best to isolate it from air to prevent the combustion and explosion of sulfides as well as air convection
