Membrane separation is a technology that uses separation membranes as the core for the selective separation, concentration and purification of substances. The basic principle is to use the different rates of dissolution and diffusion of each gas component in the separation membrane at a certain pressure, and therefore the different rates of permeation through the fibre membrane walls due to the partial pressure d...

The oxygen and nitrogen products produced by the air separation unit in the external compression process are low-pressure oxygen and nitrogen from the upper column, which are sent out of the cold box after being reheated by the heat exchanger. The product gas pressure out of the cold box is generally 0.12MPa. After being compressed to the pressure required by the user by the oxygen compressor, it is sent to the user’s pipeline. The internal compression process of oxygen is that liquid oxygen products are directly extracted from the condensing evaporator, compressed to the user's required pressure by the liquid oxygen pump in the cold box, and then sent to the user's pipeline after reheating and gasification by the heat exchanger.
