Oxygen product: liquid oxygen is pumped out from the lower tower plate of the low pressure tower and sent to the storage tank, the inner compressed oxygen pump is placed next to the liquid oxygen storage tank, the liquid oxygen extracted from the storage tank is pressurized by the oxygen pump and sent out after gasification and reheating in the main heat exchanger to get the required oxygen product in liquid air separation plant.
The nitrogen product is pumped from the top of the pressure tower and the pure nitrogen is reheated in the main heat exchanger and then sent out of the cold box, and then compressed by the nitrogen cycle compressor. The gas nitrogen products are pumped from the first and second sections of the nitrogen cycle compressor respectively.
Dear air separation manufactures liquid nitrogen product: liquid nitrogen from the top of the low pressure tower is pumped out into the storage tank.
