Application of Membrane Separation Technology in Hydrogen Purification of Generators
The low hydrogen purity of the generator is a common defect in each generator unit.The de-crease in hydrogen purity will increase the ventilation loss of the generator,affect the operation of the unit and increase the maintenance cost.This paper analyses the common reasons for the low hydrogen purity of a generator unit from multiple perspectives,and briefly introduces the basic principles,working condi-tions,advantages and disadvantages of commonly used hydrogen purification technologies.After the hydro-gen purification device based on membrane separation technology is applied to the gas generator unit,the hydrogen purity of the generator can be increased to over 98%within 2 days and maintained at a high puri-ty level,which effectively solves the problem of hydrogen purity,providing reference for the design and se-lection of hydrogen purification device for the generator.
