CB 17: Biogas CO₂ Recovery & Liquefaction System

Cold Jet’s CB 17 system offers an unparalleled solution for large-scale biogas upgrading operations. This advanced CO₂ recovery unit efficiently captures and liquefies significant volumes of carbon dioxide (CO₂ gas) directly following the biogas upgrading process, effectively eliminating methane emissions and substantially reducing CO₂. This not only delivers major environmental benefits but also unlocks substantial new revenue streams for your business.

The captured CO₂ emissions are channeled into the CB 17 unit, where the gas undergoes a robust process of purification, compression, and liquefaction. Once converted to liquid, this high-quality CO₂ is then available for diverse industrial applications, including use in greenhouses or for producing dry ice. Leveraging this recovered CO₂ creates new income opportunities, significantly lowers the carbon intensity (CI) score of your upgraded biogas, and eliminates methane leakage – marking a major stride in environmental improvement.

With a modular design built for scalability, the CB 17 unit can be precisely customized to meet the demanding needs and higher production capacities of larger biogas upgrading plants. This ensures maximum efficiency in CO₂ recovery, transforming off-gas from biogas plants or other high-purity sources into reusable, high-purity liquid CO₂, even suitable for food-grade standards. The comprehensive process includes compression, cooling, liquefaction, and a final distillation step. Importantly, any impurities removed during purification are thoughtfully redirected back to the biogas plant, further preventing methane emissions and boosting overall plant efficiency while dramatically cutting down on environmental waste.
