• Proven solution for process emission streams containing VOCs or HAPs
• Able to achieve VOC outlet concentration levels of only a few ppm, which is in compliance with the more restrictive local regulations
• Creates a sustainable option to recover and reuse VOCs
• No risk of the formation of dangerous toxins like dioxins, secondary pollutants, or greenhouse gases since there isn’t destructive combustion
• The process strictly relies on phase changes (solid↔liquid, liquid↔gas) by decreasing vapor pressure to a low temperature and condenses/freezes the VOCs by cooling the stream with liquid nitrogen or another cryogenic fluid
• The process is very safe as it does not involve sources of risk, like hot temperatures

• Skid-mounted and supplied as a packaged unit
• Specially designed cryogenic condensers with finned coils with flow conditioners
  • Our patented technology for volatile compounds condensation is based on a special heat exchanger design, that is made of finned coils with flow conditioners. This particular system presents the following benefits:
    • Large surface area which allows for a fast response for peak variations of the flowrate
    • Very good resistance to thermal stress
    • Surface and volume margin for formation of low-density ice or organic solids
    • Easy handling of the recovered VOC, because the condensate is separated at a temperature close to the inlet
    • High efficiency and reduced nitrogen consumption, thanks to an advanced arrangement of economizers

• Single or dual line for regeneration
• Requires a small footprint
• Layout can be adapted to each customer’s needs in order to fit the allocated space at the production site
• Plant can be used in combination with carbon adsorbers, resin adsorbers, or scrubbers for applications that require pre-treatment
• The control system is based on a PLC
• The plant is completely automated; only start/stop commands are required for normal operation
• Reliable operation with complex control logic, thanks to reliable control algorithms based on the experience of more than 300 applications in this field

Companies often struggle to find the right balance between investment, operating cost, and system reliability. Cryogenic Condensation is a reliable solution for VOC or HAP treatment, combining environmental sustainability and total cost of investment.
 

1. Low OPEX Cost: Liquid nitrogen is generally used as a cooling source for pollutant condensation. Since it is circulated in a dedicated circuit and it is never in contact with the effluent, the nitrogen is not contaminated and can easily be reused in gaseous form inside the factory network.
2. Safe: With Cryogenic Condensation, safety is not an issue. The units do not present a fire risk, even in the presence of highly flammable compounds in the effluent or in the environment, since no ignition source is introduced in the process. Thanks to this feature, units are suitable for installation inside ATEX classified areas without impacting the project.
3. Flexible Solution: The plant is highly adaptable and can handle various stream flowrates and VOC concentrations. The unit can work in a wide range of operating scenarios with minimum impact on normal operating costs. The automatic control system allows the plant to easily adapt to new working conditions.
4. Value Added: As a recuperative technology, solvents in liquid form are collected in a dedicated tank, thus allowing an easy reuse in plant processes. In the event that reuse is not an option, solvents can easily be collected as waste without generating any additional by-product or creating wastewater.
5. Eliminates Secondary Emissions: No secondary emissions (CO, CO2, NOx, etc.), which may require additional purification, are created in the process. The technology is based solely on the condensation of the pollutants. This saves time and money while producing superior results that are also better for the environment.
