THREE
THINGS YOU NEED TO SEPERATE NITROGEN FROM AIR
|
|
First : BF Technology
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.

Second : The Carbonaceous Moleculer Sieve
Our subsidiary, Carbo-Tech, has pioneered the scale-up of the production
of narrow pored Carbonaceous Molecular Sieves to an industrial level.In
one multi-step process an ultra-fine, pore structure is formed in the
molecula sieve pellets. This structure facilitates easy separation of
different sized oxygen and nitrogen molecules. CMS is the crucial element
of any PSA Plant utilizing the BF-Process. We know the raw material
right down to the finest pore-sub-bituminous coal. The resulting characteristics
of CMS are unique. It is highly resilient towards long term pressure
swing usage. Moreover, the excellent auto-regenerative characteristic
of the sieve leads to many years of high quality nitrogen production.
Hence, one
CMS charge lasts as long as the PSA-Plant. This makes it a safe long
term investment.

Third : The Plant
Those
that choose a pressure swing adsorption plant utilizing our process have
good reasons. Our business partners value synergistic effects between
process, CMS, and plant. This results in advantages rarely combined in
one process. Here are some examples to prove this in terms of progress
and economics. |
|
The
first example concerns the particularly long plant life, the second
the fully automated operation of the plant. In fact, after the first
day there are no personnel costs since the plant runs fully automated
and trouble-free.The low energy costs are doubly advantageous as they
result in lower over-heads and a cleaner environment. Nitrogen is all
around us, and it is surprisingly easily separated, given three things
- our process, the CMS, and the plant. Facts and figures prove our performance.
more than 2,000 plants are in operation worldwide utilizing the BF-Process
and the trend is rising.

| In
addition to nitrogen, hydrogen can also be separated from process and
coking gas; methane from landfill and pit gas; and helium from natural
gas. In these cases it is also true that the "simpler" the principle,
the more broadly based is its success. |

N2
PURITY
It is
most economical to produce 98% pure N2 from PSA Plants.
For applications which permit upto 0.5% Oxygen impurity, 99.5% pure
N2 is generated by PSA Plants only. For Applications
requiring better purity, 99% pure N2 is produced by PSA
Plant followed by a Deox Catalytic Purification Unit, so that oxygen
in the product nitrogen gas is brought down to level of 3 PPM. |
