The fine and specialty chemical sector and the pharmaceutical industry use solvents to manufacture products and to distribute/store final or intermediate products. This can pose a challenge for manufacturers, who must ensure that volatile organic compounds (VOCs) are not unwittingly released into the atmosphere.
As VOCs represent a serious health and environmental hazard, their release is strictly regulated by law. Manufacturers must also control evaporation losses, as their products can otherwise literally vanish into thin air.
CIRRUS vapour emission control (VEC) is a modular, flexible, compact and efficient waste gas treatment solution.
VOC recovery with CIRRUS
Cryogenic condensation of VOC loaded off-gas streams with liquid nitrogen is an ideal way to efficiently condense VOCs and capture them so they can be routed back into the process or further treated.
CIRRUS portfolio - flexible design
We offer a wide range of complete cryogenic solutions.
During cryogenic condensation, freezing can occur inside the main cryogenic condenser. Depending on the specific VOC mixture, this can be caused by the high freezing temperature of certain VOCs or a high level of water vapour. This freezing impacts process efficiency as it lowers the operation time of the cryogenic condensation unit(s) and increases the time needed to defrost them.
The PC500 pre-condenser is an upstream option for our CIRRUS® M500 VEC system portfolio and provides an extended operating window for the complete system. It eliminates high freezers and water and also reduces process temperatures to as low as –30°C (–22°F).
The main benefits of using our pre-condenser are:
Our service and support
We support all steps in the project management cycle, from planning to installation and start-up. We also offer gas supply and after-sales support. In addition, customers have the option of participating in test runs at our pilot plant or conducting trials at their own site.
All units are available for short-term test rentals. Our equipment pool comprises at least one unit of each size.
