VOC Emission Treatment 

 

Two different technologies are available for VOC abatement systems. Cryogenic abatement uses liquid nitrogen (-196°C/-320°F) as a cooling agent in a specific heat exchanger through which gaseous effluents pass. Chemical solvents are condensed and the purified gas is released. Solvents are then easily recovered to be reused or stored in a safe area.  

Specific features

In the broad portfolio of existing technologies for VOC emission control, cryo-trapping is specifically adapted for high VOC concentration and gas streams below 2000 Nm³/h.  

Advantages

• High flexibility in terms of gas stream and VOC content ;
• Very low maintenance (no rotating devices) ; and
• Nitrogen is usually recovered at the outlet of the installation and used for applications such as inerting.
