Corrosion of the tube sheet in the heat exchanger for constant pressure and reduced pressure crude oil processing in the petrochemical industry
Thread Content
Corrosion of the tube sheet in the heat exchanger for constant pressure and reduced pressure crude oil processing occurred; since medium vacuum residue oil flowed inside the tube bundle, which is a heavier-quality oil at a temperature of around 280 degrees, corrosion caused by naphthenic acids developed after more than 2 years of use. Therefore, attention should be paid to corrosion in this area.
In the petrochemical industry, the tube sheet of the heat exchanger in the vacuum crude oil distillation unit is prone to corrosion by naphthenic acids after long-term operation, due to the use of heavy oil and operating temperatures of around 280°C. Therefore, corrosion protection measures for such equipment should be strengthened, along with regular inspection and maintenance, in order to extend the equipment’s service life. .
Can it be even blurrier? It’s strange; I’ve never seen anything like this. Welcome to visit and provide your feedback: https://bbs.hcbbs.com/thread-5669064-1-1.html (Source: Haichuan Chemicals Forum)
