查询词典 air gas

The pump body consists of suction chamber, liquid storage chamber, turbination chamber, liquid return port, gas-liquid separation chamber, etc. After the pump starts normally, the impeller will suck the liquid in the suction chamber and the air in the inlet line so that the both can mix fully in the impeller. Due to the centrifugal force, the liquid along with the gas flows towards the outer edge of the turbination chamber and then a belt of white foam with a certain thickness and a liquid ring with high-speed rotation come into being on the outer edge of the impeller.

Dehydration process based on hollow fiber composite membrane is one of the crucial and effective methods to remove water vapor from industrial gases such as light hydrocarbon, compressed air, natural gas and so on. Dehydration of propylene with VP method was studied in the thesis. We prepared the PVA/PS、CS/PS and PVA-CS/PS hollow fiber composite membranes by spread method. The permeation behavior of water vapor among coagulable light hydrocarbons through composite membranes and asymmetric membrane was researched by vapor permeation method. Also a differential mathematical model was established which can describe dehydration of gas phase propylene.
