Cryogenic Condensation of VOC  [ Return towards  Applications  ]

Principle

Liquid nitrogen (-196°C/-320°F) is used as the 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 voliate organic component (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.
