The recovery andsubsequent reuse oforganic molecules
The recovery and subsequent reuse ofthese organic molecules often leads tosignificant economic savings. Althoughall industrial processes tend to favour therecovery of these compounds, there aremany cases in which, due to recoveryperformance-related restrictions or othercauses, complete VOC recovery cannotbe achieved.
Systems developed
Nippon Gases has developed a mixed system of adsorption and absorption plus cryogenic recovery.
When the flows to be treated are medium-to-high and
the volatile organic compound concentrations are
relatively low, turning to adsorption systems (activated
charcoal, zeolites, etc.) is the perfect solution to recover
these compounds and eliminate the polluting emissions
to the exterior. The basic principle of this technique is
the condensation of the VOCs present in the effluent by
cooling the gas flow to very low temperatures. This
cooling is produced by using liquid nitrogen as coolant,
which has a temperature of –196º C.
