 Working Principle

Air liquefaction by turbo expander refrigeration cycle principle. According to the different liquefaction point of oxygen and nitrogen, we get high pure nitrogen gas(nitrogen purity 99.99%) and oxygen gas (oxygen purity 99.6) after second rectification. It also could get some liquid gas.



2. High Purity Nitrogen Air Separator Plant
