Working Principle of Air Separation Distillation Tower

Screw compressor bearing burnt out

As for the oxygen generator in the flow of switching heat exchanger, in order to achieve the self-elimination of moisture and carbon dioxide, the amount of dirt and nitrogen is relatively large, so the condition of not freezing can be guaranteed. Therefore, the amount of pure gas and nitrogen products is relatively small, it can only reach 1.3 times of the output of gas and oxygen at most, so the amount of pure liquid nitrogen provided by the lower tower is less, so a stream of sewage nitrogen can be extracted to the upper tower, which increases the reflux ratio of the distillation section of the upper tower, it has greater rectification potential, thus allowing more inflated air to enter the upper tower to prevent inflated air from passing by and affecting oxygen extraction rate. As for the oxygen generator in the process of purification, pressurization and expansion of molecular sieve, the quantity of pure gas and nitrogen products has been greatly increased due to the lack of sel...
