Nitrogen plant

The separation of gases

Principle of the membrane systems is the difference in the rate of penetration of components of gas through the membrane material. The driving force behind the separation of gases is the partial pressure difference on different sides of the membrane.

Technology

Since the nitrogen plants, operating on the basis of membrane separation of gases, the characteristics of the membranes is continuously improving. Modern gazorazdelitelnaya membrane represents no longer a flat plate or film and hollow fiber. Polovolokonnaya membrane consists of porous polymer fibers to put on its exterior surface gazorazdelitelnym layer.

Membrane cartridge

Structurally membrane is linked in the form of a cylindrical cartridge, which is a coil wound with its special polymer fiber. Gas flow under pressure is fed into bundle of membrane fibers. Because of the different partial pressures on the external and internal surfaces of the membrane separation of gas flow occurs.
