Membrane Separation

Technology Overview Project Case

Due to membrane separation’s function of separation, concentration, purification and refining, and characteristics of high efficiency, energy saving, environmental protection, molecular-level filtration and simple filtration process, and easy to control, it has been widely used in the field of food, pharmaceutical, biotechnology, environmental protection, chemical industry, metallurgy, energy, water treatment, electronics and etc. It has produced huge economic and social benefits and become one of the three important gas separation technologies (PSA, cryogenic separation and membrane separation).


Technical Features:

Our company has provided the customers with a large number of membrane separation equipments, wherein more than 50 units of the membrane method hydrogen recovery units have been built and put into production.

We have the following advantages:

  • High recovery rate of effective composition;

  • Long service life: more than a decade;

  • Continuous operation reliability: Not affected by changes of process conditions, resistance to all kinds of impurities;

  • Wide application range: can adapt to gas separation of various compositions;

  • Low energy consumption: can reduce the production cost by 1/2.
