Gas upgrading

Future-proof resource economy

A comprehensive, reliable supply of renewable energy and the ability to produce regenerative fuels such as bio-LNG and bio-CNG are key to decarbonisation and energy transition efforts. Whether it’s combined with our dry anaerobic digestion technology, namely Kompogas™, or with our wet anaerobic digestion technology to create a complete solution or deployed on a standalone basis, gas upgrading technology to biomethane completes the range of Kanadevia Inova technologies, enabling energy to be produced from any sort of organic waste or biomass – in this case employing an upgrading process to convert raw biogases into high-purity biomethane that can be used as a versatile energy source.

A by-product of the process is carbon dioxide, which can be used to generate additional revenues in the form of gaseous, liquefied or solid carbon dioxide deployed as an industrial product gas – for example, in plant breeding, as an extinguishing agent or refrigerant, or as a raw material in the chemical industry.

Our biomethane technology thus makes a major, direct contribution to efforts to increase the use of renewable energy, phase out fossil fuels, and decarbonise the society in which we live.

Advantages of biomethane

Raw gases from a wide range of different sources are suitable for upgrading: the digestion of municipal green waste, organic household waste or agricultural biomass. Sewage and landfill gas can also be converted into energy. This extends a plant’s value chain and promotes the circular economy.

Depending on the composition, the raw gas pretreatment may be required. Then comes the main process, where the carbon dioxide in the stream of gas is separated from the methane, with the resulting biomethane conditioned to the desired quality parameters.

In consideration of the requirements and circumstances, Kanadevia Inova offers two separation processes: amine scrubbing and membrane technology. Both guarantee the highest quality and maximise the purity of the methane.

Biomethane is highly versatile. It can be used to generate heat and power or as a compressed or liquefied biofuel. Given that it is natural gas quality, it can be transported and stored in the existing gas grid infrastructure. Unlike fossil fuels, biomethane is a sustainable energy source and can be produced on a calculable basis.

The technology’s modular container construction allows several units to be combined, enabling plants to be designed flexibly to upgrade gas volumes of between 100 m³/h and 2,000 m³/h or even greater.

Further related technologies

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

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.
