Should the inner wall of the methanol storage tank be anti-corrosion? If so, what kind of anti-corrosion material should be used?
Carbon steel does not need to be anti-corrosion. Methanol is a super strong solvent and it is quite difficult to anti-corrosion.
In 2008, there were two posts about the anti-corrosion of methanol storage tanks. You can click on the following links to see the answers of previous seniors. I believe they will be helpful to you. :victory: http://bbs.hcbbs.com/thread-247543-1-1.html http://bbs.hcbbs.com/thread-196786-1-1.html
If there is no internal floating roof storage tank without nitrogen sealing and no internal anti-corrosion, there will probably be corrosion on the inside of the upper part of the tank. Do you have any doubts?
The storage tanks I have seen are not made of this type. Generally, the internal floating roof type is not used. I think the cost of anti-corrosion is a bit high.
The construction project I am responsible for does not have a vault floating plate.
The inner walls of methanol storage tanks are chemically cleaned. After chemical cleaning, a passivation film will be formed on the inner wall. Moreover, methanol is very corrosive, so there is no need for anti-corrosion.
No, as long as the deesterification and cleaning are completed. Normal nitrogen sealing
There is no need to do anti-corrosion, nitrogen sealing is very important.
There is really no need to do it. We have designed 20,000 cubic meters and haven’t done it yet.
There is no need for anti-corrosion. I have never made 2,000, 3,000, or 20,000 pieces before. Some design institutes also design anti-static and anti-corrosion layers, which I think is redundant. There is absolutely no need for anti-corrosion with an internal floating roof.
There is no need for anti-corrosion. Methanol is very corrosive. In my unit, there are two finished tanks each containing 5,000 cubic meters that are not anti-corrosion.
There is no need to consider corrosion for refined alcohol tanks, but corrosion should be considered for crude alcohol tanks. It is best to use stainless steel for reconstruction ； It has been built and made of carbon steel. After a while, add some alkali tablets to the underground tank and pump it into the tank with an underground pump to reduce corrosion.
