The desulfurization tank is severely corroded
Thread Content
Recently, the desulfurization regeneration tank in our company has suffered severe corrosion; it is almost unusable after only one and a half years of use. If anyone has encountered this situation or knows the reason, please share some advice. Thank you!
You have described too little; more detailed information should be provided. There are many types of corrosion, and in most cases, corrosion in storage tanks is caused by problems with the material used. However, the possibility of electrochemical corrosion and environmental corrosion cannot be ruled out.
The causes of corrosion can only be further analyzed and determined by understanding the actual operating conditions. If it is confirmed that corrosion is unavoidable, it is recommended that new desulfurization tanks be made of stainless steel or of carbon steel with internal anti-corrosion treatment.
It would be best to discuss this with the process engineers at your company to see if corrosion of HS_ has occurred
I was responsible for manufacturing desulfurization regeneration tanks. At our company, the inner and outer walls of these tanks were coated with epoxy resin six times, which usually ensures a service life of seven to eight years. Is the anti-corrosion treatment used on your tanks too simple?
Another possibility is that when you designed it, the wall thickness of the cylinder was chosen to be too thin
The poster should provide information on the material, thickness, specifications of the desulfurization tank, as well as the operating conditions (medium composition, temperature, pressure); perhaps only then can the specific cause be identified.
