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.
