Performance evaluation of air separation equipment

What are the driving forms for the compression mechanism of large-scale air separation equipment?

  In the small air separation unit, when gas or liquid flows through a shrinkage hole or valve in the pipeline, the flow will be hindered, and the fluid will produce vortex collision, friction and other resistance at the shrinkage hole or valve. In order to flow through the shrinkage hole or valve, the resistance must be overcome, showing that there is a pressure difference before and after the shrinkage hole...
