Why insist on an Atlas Copco oil-free solution
for your chemicals production?
For greater product purity, more effi cient processes,less wastage and increased safety.
Air separation: lower costs, purer gases
In PSA plants components of air -nitrogen and oxygen- are separated
using membranes. Any oil in the compressed air will be deposited on the membranes,
which then have to be replaced at a huge cost. Contamination of the gases
will also be a result.
Fermentation: healthy bacteria, no product contamination
Compressed air supplies oxygen to the bacteria during fermentation
to produce such chemicals as citric acid. The presence of even
small oil traces will kill the bacteria and contaminate the end product.
Control
systems:
smoother functioning, pure end products
In control valves and actuators activated by compressed air,
contamination causes malfunction and jamming. Moreover, instruments
always vent air, which if oily, will spoil the end product
and cause harm to humans.
Aeration:
higher quality processes and products
Compressed air plays a direct role in aeration processes,
supplying oxygen for the oxidation of chemicals. Traces
of oil will hamper the process and may even result in a different end
product.
Hazardous
processes:
increased
safety and security
In some chemical processes, oil-free air is most critical
to eliminate the possibility of explosions. An example
is the generation of oxygen from compressed air and its
subsequent compression and use.
PET production:
enhanced product quality, safer processes
PET resin beads are produced and transported using compressed
air. Oil in the compressed air will contaminate the resin.
Result: a different composition of the end product when
the beads are sintered. Also, a fire
hazard.
Pneumatic transport: prevents defects
and pipe clogging, increases safety
Compressed air is used for pneumatic transport of materials
such as PVC, PTA and DMT chips. Oil contamination will
cause quality defects and
pipe clogging, as well as a fire hazard.
