PSA Nitrogen Gas Plant
The idea of separating nitrogen from air by an adsorptive process was equally off-beat as it was fascinating. But in the early 70's Bergbau-Forschung managed just that. Since then we licence the BF- Process to separate nitrogen from air worldwide. This process is based on the Molecular Sieve Effect Facilitated by special custom-made activated carbon.The principle of the process is surpris- ingly simple and very effective. Two adsorbers, used alternately, are filled with the Carbonaceous Molecular Sieve or CMS. To begin with, one of the two adsorbers is filled with air under pressure.Then, the Molecular Sieve adsorbs mainly oxygen, and a nitrogen rich gas leaves the adsorber.

            Simple pressure reduction regenerates the first adsorber. In the meantime the second adsorber starts the production cycle. Cycle times of as short as 1-2 minutes for adsorption and desorption ensure a constant nitrogen supply.
