How to address scaling on the rotor of a circulating hydrogen compressor?
Thread Content
The rotor of the cycle hydrogen compressor in the diesel hydroprocessing unit is severely fouled, with a layer of black scale on its surface; analysis shows that gums account for about 50% of this fouling. It can be cleaned off using high-pressure water. How can this problem be completely resolved from a process perspective?
This issue regarding production processes is suitable for discussion in the petrochemical sector; I’ll help you transfer it there
In my opinion, it is necessary to strictly control the quality of the manufacturing processes at each stage, ensuring that every step meets the standards specified in the technical regulations.
Add more water for high-pressure air cooling; the water can wash it away, as it is usually ammonium salts.
1. The issue with lean amine solution: The circulating hydrogen desulfurization tower uses a lean amine solution containing coke powder, which adheres to the rotor； 2. Problem with the lean amine liquid pump: Industrial white oil seeps into the lean amine liquid, and the circulating hydrogen carries small droplets of this industrial white oil into the circulating hydrogen compressor.
