CO2 Purification and liquefaction
What we do
We design and deliver high-efficiency CO₂ purification and liquefaction systems tailored to a wide range of by-product streams from biogenic or industrial CO₂ sources. Our solutions are engineered to ensure stable operation, low energy consumption, and consistent product quality meeting both industrial and food & beverage grade quality demands.
Our CO₂ purification and liquefaction solutions allow customers to recover CO₂ from:
- Hydrogen production
- Fertiliser production
- Biogas or biofuel production
- Ethylene Oxide production
- Other high containing by-product streams
Purified and liquefied CO₂ can be utilized across multiple value chains. By combining robust process design with proven purification technologies, such as scrubbing, adsorption, catalytic oxidation and cryogenic distillation, we ensure that each system meets the specific purity and capacity requirements.
Our CO₂ purification technologies enable the production of:
- Industrial-grade CO₂
- Food-grade CO₂
- Beverage-grade
- PtX-grade CO₂
- CCS/CCU -grade
- EIGA Doc 70 compliant CO₂
- ISBT compliant CO₂

High CO₂ concentration sources
>95% CO₂
Range: 25 – 1000 tons/day
Heat consumption: None
Power consumption: 165 – 225 kW/tons
Water consumption: 0 – 500 L/ton CO₂
Product quality: Industrial-, food-, PtX- and EIGA Doc 70 grade
High concentration sources include Biogas, fermentation, and certain chemical and petrochemical waste streams. CO₂ sources are generally considered as being high-concentrations when the CO₂ content exceeds 95%.
CO₂ Sources and Applications
Our CO₂ purification and liquefaction solutions are suitable for both high-concentration and captured CO₂ streams, including:
- Biogas and biomethane upgrading plants
- Fermentation and distilleries
- Carbon capture (CCS and CCUS) applications
- Chemical and industrial processes
Purified and liquefied CO₂ can be utilized across multiple value chains, supporting circular economy principles and the transition to low-carbon energy systems.
Reliable CO₂ Liquefaction Solutions
With extensive experience across CO₂ capture, purification, and liquefaction, we deliver integrated solutions that maximize uptime, product quality, and operational reliability.
Our expertise enables us to design the right CO₂ purification and liquefaction solution for each project—supporting efficient decarbonization and the creation of valuable CO₂ products.
Integrated Carbon Capture and CO₂ Purification and Liquefaction Solutions
Our CO₂ purification and liquefaction systems can be delivered as stand-alone units to serve the merchant CO2 market or fully integrated with upstream processes such as biogas upgrading, and carbon capture (CCS and CCUS).
By designing the purification and liquefaction process as part of the overall plant layout, we ensure optimal energy efficiency, stable operation, and seamless integration with existing or new decarbonization facilities. This integrated approach enables our customers to maximize CO₂ recovery, reduce operational complexity, and unlock additional value from both biogenic and industrial CO₂ streams.
Press releases
Not all CO₂ is created equal
Food-grade CO₂ CO₂ plays a vital role in the food and beverage industry, where purity, safety and sensory quality are essential. Two internationally recognized standards define food-grade CO₂: EIGA and ISBT. To qualify as a food-grade, CO₂ must...
