Oxygen plant

In a gas separation membrane environments using the oxygen plant is the difference in penetration rates of components in the gas mixture through the membrane material. The process of separation due to the difference in partial pressures on different sides of the membrane.

The operating principle of the membrane cartridge

Modern gaz membrane is a by no means a flat plate or film and hollow fiber. For the technology of membrane separation of gases used modern polovolokonnaya membrane consisting of porous polymer fibers to put on its exterior surface gazorazdelitelnym layer. Structurally polovolokonnaya membrane is linked in the form of a cylindrical cartridge, which is a coil wound with its special polymer fiber. Porous fiber has a complex asymmetric structure, the density of the polymer increases as we approach the external surface of fibers. The use of porous substrates with asymmetric structure allows to separate gases at high pressures (up to 6.5 MPa).

Gazorazdelitelnogo fiber layer thickness does not exceed 0.1 microns, which provides high specific permeability of gases through the polymer membrane. The current level of technology allows the polymers to possess high selectivity in the separation of various gases, which, respectively, for high purity gaseous products. Modern membrane module used oxygen plants, consists of a replaceable membrane cartridge and the housing. Packing density of fibers in the cartridge reaches the values of 500-700 square meters of fiber in one cubic meter of the cartridge, which minimizes the size of the oxygen plant.
