Corrosion and leakage in the overhead heat exchanger of the coking unit’s distillation column
Thread Content
Last week, an inspection of the top circulation heat exchanger in the fractionation tower of the delayed coking unit where I work revealed oil in the cooling circulation water, indicating a leak in the tube bundle; repairs are currently underway. Since we process Tahe crude oil, which is highly corrosive, let’s discuss how to prevent corrosion in the coking unit Thank you to all the sea friends.
Upgrading the heat exchanger material can be considered. We are still using carbon steel tube bundles, but corrosion is quite severe; once leaks are detected, repairs or replacement of the tube bundles are required, which involves a lot of work.
Dude, if nothing else works, you could consider using a PTFE heat exchanger – it works really well
I suggest posting in the anti-corrosion section; there are more people here who work on container design, and fewer users
1. Ensure the quality of circulating water. 2. Upgrade the material of the heat exchanger tube bundle. 1# Mosanxi
