Cathodic protection for biogas to natural gas purification equipment
Thread Content
Question: Our company is currently operating a small chemical plant that purifies biogas into natural gas. During operation, condensate water is generated, and this condensate causes certain corrosion on the inner walls of the stainless steel pipes as well as those of the carbon steel pipes in the plant. I would like to ask the experts: what type of cathodic protection can be used to minimize this type of corrosion, and how should the costs be estimated? What is the estimated cost? Thank you
The inner wall of the pipeline can be coated with PTFE for corrosion protection, but it is necessary to know the operating temperature, as well as the diameter and length of the pipeline, to determine whether coating it is feasible.
How can you be sure it’s electrochemical corrosion?

Can it be coated? What is the pipe diameter?
