Gas separation unit maintenance
Thread Content
Hello everyone. I have a question: The gas separation unit has been in operation for 2 years now, and maintenance is planned. If the unit is maintained, does it mean that the towers need to be cleaned? Also, do the heat exchangers and coolers require cleaning? I would appreciate it if experienced technicians could give some advice. Thank you.
Yes, for a major overhaul, it’s necessary to disassemble the component for inspection, cleaning, and examination
If the circulating water is well managed, there should be no major issues with the coolers; if you’re concerned, you can clean them. The depropanization column of the tower can be taken apart for inspection; the two columns behind it are clean, and aside from a few float valves possibly falling out, there should be no other problems.
Due to the long operating time, it is necessary to carry out disassembly and inspection in order to ensure the safe operation of the device once it is restarted, achieving safety, stability, longevity, full performance, and excellence
I should open it and take a look even if there’s no need for maintenance.
The towers, heat exchangers, and pumps all need to be opened for inspection
After operating for a long time, maintenance should be carried out according to the plan: open everything to check for any leaks, corrosion, or blockages.
If there are no issues during operation on site, it should be opened for inspection; the decision will depend on the nature of the fault
