Renewable Gas Technologies
CO₂ recovery, purification and liquefaction
CO2-Reduction

Carbon dioxide (CO2) is a process gas needed in numerous applications. The use of CO2 from renewable sources offers numerous opportunities – both for producers and consumers.

  • 100% methane recovery

  • Power demand of 0.2 kWh/kg CO₂ input gas with CO₂ as natural coolant

  • Liquefaction efficiency up to 94%

  • CO₂ production capacities 550 / 1,200 / 2,300 kg/h

  • Food-grade product quality (ISBT/EIGA)

  • Product guaranteed to have no odour, colour, or taste

Kanadevia Inova develops and manufactures systems that capture, purify, and liquefy carbon dioxide. This makes it a transportable raw material from renewable sources that can replace fossil-origin CO2 in various applications and processes.

Basic technology scheme of the CO₂ liquefaction

CO2-Liquefaction-Process

After the purification, drying, and compression of the carbon dioxide, condensation into the liquid phase follows. Traces of other gases and impurities are removed to maximise the quality of the liquid CO₂. Remaining methane is returned to gas processing, which improves the profitability of biomethane production. The process of Kanadevia Inova is characterised by the highest gas quality, meeting the strictest standards, such as those for the food or pharmaceutical industry:

  • ISBT (International Society of Beverage Technologists)

  • EIGA (European Industrial Gases Association)

For a future where every residual material is a resource. Whether for biogas, biomethane, or other biogenic gases, retrofitting plant technology for CO₂ utilisation offers additional economic and climate-friendly perspectives. Users of renewable CO₂, on the other hand, have the opportunity to reduce their CO2 footprint by moving away from finite fossil resources.

Dry anaerobic digestion

In the age of the circular economy, ways of recycling and recovering organic waste as a renewable, natural resource are attracting increasing attention.

Wet anaerobic digestion

Biogas is a major source of renewable energy. Unlike wind and solar power, biogas can be produced on a predictable basis from replenishable, locally available waste and residues.

Gas upgrading

A comprehensive, reliable supply of renewable energy and the ability to produce regenerative fuels such as bio-LNG and bio-CNG are key to decarbonization and energy transition efforts.

Power-to-gas

Power-to-gas plants convert electricity into synthetic gases, including hydrogen and methane. The power-to-gas process involves the use of electrolysis and methanation systems.

Liquefaction
