Precautions for maintaining the methanol washing unit (preventing sulfide combustion and explosion as well as internal corrosion of the system)
Inside the tower, it is necessary to prevent sulfide combustion explosions and corrosion within the system. It is generally required to isolate air as much as possible and prevent air convection; at the same time, water must be used to flush out methanol inside the tower in order to clean the system before it can be opened for maintenance.
