Issues related to cold-start and hot-start of air separation units

Between cold-start and hot-start of the air separation unit, which condition results in greater vibration of the unit? Thank you
Large vibration? ? ? You mean fluctuations, right?
I’m not sure whether the poster is referring to the vibration of the equipment or the fluctuations in the system The lengthy process of fine-tuning when starting up the equipment gradually, step by step – it should have no adverse effect on the equipment, unless the operating load is too high. With proper adjustment of the system, there won’t be any significant fluctuations ； When starting the machine in cold conditions, it responds normally in the short term; the operations are rapid, and this can be considered a rough adjustment process, with rapid changes in the system. If you react quickly and make swift adjustments, there won’t be significant fluctuations. However, this places a heavy strain on the equipment, especially the air compressor. It will be fine as long as your ATC system is able to keep up with the speed of your adjustments. Vibration is a key parameter in the operation of equipment; it has a direct impact on its performance, but it doesn’t have much to do with starting the equipment in cold or hot conditions.
For air separation systems equipped with air compressors, vibration is generally greater during cold start-up compared to hot start-up.
