Nitrogen plant

Nitrogen installation work on the basis of adsorption technology, based on varying the speed according to the absorption of individual components of a gas mixture of pressure and temperature. Among the several types of adsorption nitrogen plants for production of the largest in the world have been installing shortcycle adsorption.

Scheme of the process used by plants with nitrogen in such systems, based on the speed of absorption of components shared by the gas mixture and the regeneration of adsorbent by changing the pressure in the two adsorber - vessels containing adsorbent. This process operates at temperatures close to room. When using this scheme is performed by fixing nitrogen at a pressure above atmospheric.

The process of adsorption shortcycle in each of the two adsorbers consist of two stages. At the stage of absorption occurs predominantly adsorbent to capture part of the gas mixture to obtain the product nitrogen. At the stage of regeneration sequestered component is allocated from the adsorbent and play into the atmosphere. Then the process is repeated many times.
