What is the material of benzene removal tower?
Thread Content
I recently read an article about corrosion and protection of benzene removal towers. It mentioned that in the past, the material was mostly HT200. First, stainless steel materials such as 0CR18NI9 were used. Our factory is still cast iron. I don’t know what material you use there?
The tower body of the benzene removal tower can be made of cast iron or stainless steel. No matter which one is used, the strength requirements must be met first, and then the necessary corrosion allowance must be considered.
We use SUS304 material
It is recommended to select materials according to the petrochemical equipment material selection guidelines. SHT3096-2001 Main equipment design and selection guidelines for key equipment for processing high-sulfur crude oil. Remember that there is also a petrochemical media selection chart on the forum. Please check it out. This post was last edited by qldch2306 on 2009-2-11 08:29 ]
We first used cast iron, but now all new processes use 304, mainly to reduce weight and prevent corrosion.
