Problems after the compression, condensation, and liquefaction of exhaust gases
Thread Content
After the low-pressure off-gases from the batch polypropylene plant are compressed and condensed into a liquid state by a compressor, is it necessary to temporarily store them in a liquid tank before feeding them into the feed tank, regardless of mass considerations? Can it flow directly into the raw material tank?
After condensation in the heat exchanger, the gaseous propylene must pass through a buffer tank before being pumped into the storage tank by a centrifugal pump. The absence of a buffer tank leads to unstable inlet pressure in the transfer centrifugal pump; moreover, without level control, changes in the amount of condensation can easily cause air entrapment and cavitation, preventing the pump from delivering fluid properly and even damaging the pump itself. I will provide an answer according to my setup.
