Causes and solutions for pipeline vibration before air cooling in the gas separation unit?
Thread Content
The air separation unit’s propane tower and propylene tower experience significant air-cooling vibrations, manifesting as resonance with periodic frequency vibrations. Is it resonance caused by the air-cooled fan or by the internal airflow? How to eliminate it?
Is the air cooling in your factory wet air cooling?
Is it resonance caused by the air-cooled fan or by the internal airflow? How to eliminate it? Answer: Both ； Solution: Wrap the outlet pipe with 10 mm thick glass wool, and cover it with galvanized iron sheet; this will serve to reduce noise.
Additionally, this method is widely used; large turbines in air separation units are treated in this way, which reduces noise by about 30 decibels or more. Moreover, it is advisable to install soundproof enclosures around the fans and soundproof walls at the inlet, as this will yield even better results.
