VOC’s Emissions Control

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 charchoal, 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.
