The pump-down time will additionally be influenced by the leakage rate of the vacuum system, the conductances of the piping and of vaporizing liquids that are present in the vacuum chamber, as well as by degassing of porous materials and contaminated walls.


Dense Phase pneumatic transport, pressure, vacuum ...

A vacuum dense phase system is quite similar to a lean phase setup except that a vacuum pump allowing to reach pressure <-900 mbarg should be installed. The inlet of material is usually done through a sender hopper. No specific construction for the sender hopper is needed, which can be an advantage compared to pressure dense phase since the ...
