Weekly Topic 11: Storage of Glacial Acetic Acid
Thread Content
This post was last edited by shiwang528 on 2011-7-11 12:20. Today, let’s discuss the material used for acetic acid storage tanks. (P Provided by Haiyou wo-call-you, thank you.) Glacial acetic acid is an important type of industrial/chemical raw material. Let’s discuss its storage. We know that glacial acetic acid can corrode steel at room temperature. So, if a tank is to be built, which type of steel offers sufficient corrosion resistance while remaining cost-effective? If glacial acetic acid needs to be heated to 60 degrees Celsius, then which steel should be chosen? And why? Weekly topic: Note: 1.

Based on my experience, the steel material must be selected carefully. Under normal room temperature conditions, 304SS can be used as the most suitable material. If the volume of the tank is less than 50 cubic meters, an aluminum alloy can be used, but its purity must be above 90%; however, the strength of such tanks is relatively low. If glacial acetic acid is to be heated to no more than 60 degrees Celsius, SS316L is a good choice.
Glacial acetic acid is one of the important raw materials in the chemical industry. Let’s discuss the storage of glacial acetic acid. We know that glacial acetic acid can corrode metals at room temperature. Therefore, if storage tanks for storing glacial acetic acid are to be built, the material used for these tanks must be highly corrosion-resistant and inexpensive. If glacial acetic acid is heated to 60°C, what type of material should we choose to manufacture the storage tank? And why choose? Based on my experience, this material should be chosen carefully. Under normal temperature conditions, 304SS material is likely the most suitable choice. If the volume of the tank is less than 50 cubic meters, aluminum alloys with an aluminum content of over 90% can be used, but their strength is quite low. If glacial acetic acid needs to be heated above 60°C, ss316L material is a good choice.
The one upstairs is really interesting; the translation is good. To be honest, my field of expertise is not in Chemical Mechanics but in Chemical Engineering and Technology. More precisely, I was hired by a joint venture company as a Chemical Process Engineer. However, after working there for about 4 months, I still feel like an idiot. As for the materials used in our company, I can only name 304, CS, and 316. I mention these names merely to show that I support this type of discussion and hope to draw more attention to this topic.
