Adsorption Oxygen Plants
The adsorption oxygen plants produce 5 to 5,000 nm3/hr of oxygen with the purity if 93-95%. These systems designated for indoor operation are set to effectively produce gaseous oxygen from atmospheric air.
An unquestionable advantage of adsorption-based oxygen plants is the low cost of oxygen produced in the cases where there are no rigid requirements to the product oxygen purity.
Structurally, the adsorption oxygen plant consists of several adsorbers, the compressor unit, pre-purifier unit, valve system and the plant control system.
A simple adsorber is a column filled with layers of specially selected adsorbents – granular substances preferentially adsorbing highly adsorbable components of a gas mixture.
Where gaseous oxygen purity is required at the level of 90-95% with the capacity of up to 5,000 nm3 per hour, adsorption oxygen plants are the optimal choice. This oxygen purity may also be obtained through the use of systems based on the cryogenic technology; however, cryogenic plants are more cumbersome and complex in operation.

Famous quotes containing the words oxygen and/or plants:
“All the oxygen of the world was in them.
All the feet of the babies of the world were in them.
All the crotches of the angels of the world were in them.
All the morning kisses of Philadelphia were in them.”
—Anne Sexton (1928–1974)
“Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.”
—Henry David Thoreau (1817–1862)
