Membrane nitrogen plants
A membrane nitrogen plant is a set of special equipment designed to produce nitrogen from atmospheric air by the method of membrane separation at a pressure of up to 25 bar.
The production of nitrogen in this technological process is based on the principle of separation of gas mixtures in a membrane module, due to the different penetration rates of the components of the gas mixture through polymer membranes and the differential partial pressures on both sides. In the case of separation of the air mixture, oxygen has a greater permeability than nitrogen. The difficult-to-penetrate gas components (N2, CH4, CO) pass along the entire length of the generator and then come to the consumer. The output is a gas mixture with an N2 content of up to 99.9%.
The membrane installation allows to obtain high-pressure production gas (nitrogen).
