VOC Emission Control with CIRRUS Cryocondensation Technology
Cryocondensation Solutions for VOC Abatement and VOC Recovery Across Industry

Flexible, Compact and Reliable Cryogenic Technology for VOC Abatement
Increasingly strict air emission regulations challenge industry to tighten control over the release of volatile organic compounds (VOCs). Cryogenic condensation is a promising answer. Our low-temperature CIRRUS® Vapor Emission Control (VEC) technology uses the cooling power of liquid nitrogen to condense the VOCs in a vent or process gas stream. The condensed VOCs can then be captured and either routed back to the process or further treated.
In the pharmaceutical industry, for instance, CIRRUS VEC systems are an effective way to control VOCs released during the production of active pharmaceutical ingredients (APIs) so they are not unwittingly released into the atmosphere. The refining industry is another case in point. Terminal operators, oil and gas transportation companies, oil and gas storage companies, and oil and gas transfer operators are all seeking the most efficient and cost-effective method to control and prevent the emission of VOCs that are sometimes released into the atmosphere from a tank as a result of loading and unloading operations. Here also, CIRRUS is a flexible, effective answer.
With 25 years of experience and hundreds of VOC abatement installations worldwide, we are a trusted supplier of proven VOC handling solutions. We have a proven installed base across many industries, including oil and gas terminals and complexes and chemical hubs worldwide.

Benefits of CIRRUS at a Glance: Air Quality, Safety, Costs and Emission Credits
Given the health and environmental hazards of VOCs, their release is regulated by progressively stricter occupational health and safety laws including the OSHA VOC limits. Our CIRRUS VEC portfolio is based on a modular, compact design to give operators the flexibility they need to meet these evolving challenges. Family members include the CIRRUS® M50, CIRRUS® M150 and CIRRUS® M500 modules.
Looking beyond regulatory compliance, CIRRUS low-temperature condensation offers safety benefits. The vapor stream is mixed with nitrogen, which displaces oxygen and thus avoids potentially flammable mixtures sometimes seen with carbon adsorption systems and thermal oxidizers. This makes CIRRUS a safe option to capture VOC vapors. Also, the flow rate with CIRRUS is considerably lower than with air-based VOC control systems. The liquid nitrogen used to cool the CIRRUS VEC system has no direct contact with the VOCs and can be used downstream for inerting, purging and other nitrogen requirements. This reuse of VOC solvents translates into substantial cost savings.
In addition, emission credits may also potentially be generated through installation of VOC mitigation systems such as CIRRUS. In VOC non-attainment areas, the value of emission credits is also increasing rapidly, and the generation of those credits through the installation of VOC control equipment on existing point sources can represent a sellable asset.
