VOC's Emissions

Recirculation of Dryer Flows with VOCs.

The recovery and subsequent reuse oforganic molecules

The recovery and subsequent reuse of these organic molecules often leads to significant economic savings. Although all industrial processes tend to favour the recovery of these compounds, there are many cases in which, due to recovery performance-related restrictions or other causes, complete VOC recovery cannot be achieved.

Recover all VOCs
Minimise the investment
Eliminate the need for maintenance
Eliminate the cost of consumables
Adapt to legislation on atmospheric and environmental emissions
Ensure safety and “zero” risk

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.

The use of this technology ensures compliance with the strictest legal limits, both present and future.
