Sustainable, compact and easy to install, it can treat VOC laden emission streams and other hazardous air pollutants. It can also recover the gaseous nitrogen which can be used for inerting and blanketing applications.
Emissions monitoring and pollution control are priorities all over the world to help fight climate change. Management of VOC emissions is high on the agenda and industries need to continually review their emission control systems.
Cryo-Condap®, Air Products' proprietary technology using liquid nitrogen for VOC recovery can effectively abate and recover close to 100% of most VOCs.

Limit the release of methyl acetate and methanol to the atmosphere to comply with Environment Agency regulations.
Methyl acetate and methanol (VOCs) are emitted from a process on site and needed to be recovered to meet ever stringent Environment Agency laws.
Install a Cryo-Condap® system to condense the methil acetate and methanol using a heat exchanger, with the installation and control package surrounding the heat exchanger being key to providing accurate temperature control capabilities.
The system uses liquid nitrogen in a heat exchanger to cool down the process gas. The VOCs condense and freeze into particles and are removed.
Emissions have been reduced and the Environment Agency commitment to reduce the levels of solvent emitted from this process has been met. Since the unit has been commissioned, solvent has been recovered that would otherwise have been emitted to the atmosphere.
Cryo-Condap® technology has been developed, not only to meet the toughest government legislation worldwide, but also to improve process efficiency.

While the site was currently meeting its legal permit requirements, a request from the Environment Agency asked the site to reduce the emissions from the process by Best Available Technology.
The Cryo-Condap® system 's ability to cope with stop-start and fluctuating emissions profiles, as it is normally seen in a batch process, by having a "cold-sink" of a refrigerant bath is a major advantage. It does not produce the over or under cooling as would be seen by a system using direct process gas to liquid Nitrogen heat Exchange. Another advantage is the ability to create the bespoke system tailored to the process' flows and solvent loads.
