I need some help~~~ Can the inside of a methanol synthesis tower be cleaned with water? How to clean it?

It is possible to wash with water, but one cannot use the same batch of water repeatedly, as the methanol process is sensitive to chloride ions; it is best to use deionized water for washing, and then dry it with nitrogen

Sure, we wash our methanol tower with water every time the catalyst is replaced. However, it only rinses the inner wall of the outer cylinder of the tower. It is usually when the internal components are lifted out to remove the catalyst. Sometimes, a fire truck is used to simply flush the demineralized water against the tower wall from the top, and sometimes steam hoses are used to introduce steam for blowing. Finally, blow dry the moisture with air. I don’t know what the methanol production capacity of the poster is; different synthesis towers require different cleaning procedures and catalyst installation methods. We use small towers. Lianchun has only 80,000 in terms of capability.

Of course, it can be cleaned with water (deionized water). After the catalyst has been removed, it is necessary to ensure that the catalyst in each tube has been completely removed; thereafter, the tubes are blown out with air, and then heated with steam tube by tube. Finally, they are rinsed with deionized water. :victory:

Not only water, but chemical cleaning works too. Because rust can affect the methanol catalyst, leading to wax formation and a tendency toward methane production. Therefore, when there is a lot of rust on the tower walls, chemical cleaning is required; after passivation, it can be dried and used

The methanol synthesis towers here are all purged with nitrogen, and the results are very good~~~

Won’t you do water intermodal transport either? Wash with deionized water, then purge with nitrogen, and only after that is the catalyst installed, etc.

Thank you all! I’ve been nurtured a lot!
