A nitrogen generator is an important piece of industrial equipment that utilizes physical methods to separate oxygen and nitrogen in the air to obtain nitrogen.
I. Definition and Principle
Nitrogen generator refers to the equipment that takes air as raw material and separates the oxygen and nitrogen in it by physical method, so as to obtain nitrogen. Its main principles include pressure-variable adsorption (PSA) technology and membrane separation technology. PSA technology utilizes the selective adsorption characteristics of carbon molecular sieve on oxygen and nitrogen to realize the separation of nitrogen and oxygen under the pressure change; while membrane separation technology utilizes the difference of permeation rate of different gases in the membrane material to realize the separation of nitrogen.
