Corrosion issues in styrene plants
Thread Content
Dear experts: I would like to ask what corrosion problems exist in styrene plants? Where are the key areas of corrosion? What caused it? I hope the experts here will be kind enough to offer their guidance!
Styrene leak alarm – feel free to contact the manufacturer: Shandong Snoguan, phone 0531-68658651 (WeChat ID: 13256768792 for communication; thank you)
Light component removal tower top system and unit circulating water heat exchanger
What causes corrosion in the overhead system of the light ends removal tower?
It is mainly corrosion in an acidic medium; the pH value measured here is generally around 3
Is a low pH value caused by chloride ions?
No, it is now generally accepted that it is carbon dioxide corrosion
Can carbon dioxide cause the pH to drop to around 3? It’s great to be able to communicate with you.
Could you please provide information on the medium at that location? It would be best to have the test analysis results. Also, what is the material of the pipelines in that area? What are the specifications? What are the process operating conditions there (temperature, pressure, flow rate)?
Generally, 825 and 800 will do!
