Corrosion resistance measures for nitration reactors
Thread Content
Our company has a nitration unit that uses batch reactors (5m3) to carry out reactions with 98% sulfuric acid, 97% nitric acid, and difluoromethane. Initially, 321 stainless steel was used for these reactors. To prevent corrosion of the reactor material by these chemicals, would anodic protection be an effective solution? And how can it be implemented?
Why not use an enamel kettle? This process mainly involves enamel coating; what is the location of the poster?
At first, enamel reactors were considered, but after communicating with a design institute, it seemed that metal reactors would be more suitable. Mianyang, Sichuan
The first choice is still to use enamel-lined reactors; for the pipelines, other anti-corrosion measures can be considered, such as lining them with PTFE
My first reaction was, why cathodic protection? ? 、{:3_68:}
