Membrane gas separation plants

Мембранные газоразделительные установкиSince 1975 Cryogenmash has been dealing with the problems in the membrane technology based on selective permeability of gas mixture components through a polymer membrane. In 1976 for the first time in the world practice a pilot commercial plant of capacity 500 m3 /hr was put into operation intended for concentration of hydrogen at the Shchekinsky Industrial Association "Azot" for catalytic purification of argon from oxygen. Since 1980 the serial production of commercial membrane gas separation plants was implemented. In the plants use is made of hollow-fiber modules of new generation. The design features the modular principle of construction that allows, through transformation of unified modules, to provide for necessary productivity. In comparison with the traditionally used methods in separation of gas and vapor-gas mixtures, the membrane technology, as a rule, requires considerably smaller capital and operational expenses. Besides, high competitiveness of the membrane processes is provided with a complex of the following properties inherent to them:
The plants are available for various applications: nitrogen plants, plants for enrichment of air with oxygen, plants for hydrogen concentration, plants for creation and regulation of gas atmosphere in refrigeration chambers, in fruit storage facilities, such as "Bars", intended for maintenance of long storage of fruits and vegetables at minimum losses. The membrane plants are being operated at various enterprises of Russian Federation and abroad: in India, Bulgaria, Chinese People's Republic, in Taiwan, Hungary, Australia. |
