On-site oxygen solutions for biogas

The H2S gas is highly toxic and nauseous. Component both dangerous and biogas destructive, hydrogen sulfide has harmful effects on humans, the environment, building materials and other materials. The use of renewable energy and the implementation of residues containing sulfur in biogas plants pose serious problems. This measure to remove hydrogen sulfide brings a decisive contribution to optimal plant biogas operation.

NOVAIR Industries offer on-site oxygen production solutions for the removal of hydrogen sulfide in the biogas.
The use of pure oxygen for the removal of hydrogen sulphide is a simple, effective and economical process that NOVAIR Industries supplies to the biogas sector through its high purity oxygen generators which allow production and supply directly to on site.

Plant efficiency is maximized by avoiding metal sulfide formation caused by the lack of pure oxygen.
Among these solutions, NOVAIR Industries offers:

  • MODULO2, a mobile and compact oxygen generator for small facilities which need a continuous supply of oxygen on site
  • OXYPURE & OXYPURE DS-PSA, oxygen generators allowing up to 99.5% oxygen purity, thanks to their DS-PSA technology
  • The oxygen generator COMPACT-20 BIOGAS extracts oxygen from the ambient air, concentrates it to 93% (+3%) purity, and delivers the oxygen required for biogas desulfurization.

These solutions are perfectly autonomous and provide a continuous supply of oxygen for biogas production sites which require desulfurization.

NOVAIR's solution ensures the safe desulfurization of biogas with oxygen

NOVAIR designs and manufactures all the components of the on-site oxygen production solution for biogas desulfurization. The solution includes a compressed air supply, an oxygen generator, a system for regulating the flow of injected oxygen and a safety device that prevents any return of biogas to the oxygen tank, thus avoiding any oxygen/biogas mixture.
NOVAIR offers a complete range of generators that meet all needs in terms of flow rate, pressure and purity, all adapted to the production of oxygen that will then be injected into the gas stream or into the activated carbon.

"No-return" device

For the biogas application, NOVAIR offers a device designed to prevent the oxygen return in the biogas.
This regulation system was developed for more safety in accordance with risks analysis methods.

Integration solutions for rent or sale

NOVAIR solutions are available for sale or rent for integration in a technical room or in a "Plug and Play" container.

Compression and Treatment for Biogas

Novair also offers turnkey solutions for companies which need specific projects for treatment and compression of biogas.

Amongst our references

A Biogas treatment plant in Ormes was equipped with an oxygen production unit at the NOVAIR site for the desulphurization of biogas.
The Oxyswing modular PSA generator solution has enabled the capacity of the generator to be adapted to the needs of the client, which was revised upwards during the project. The installation delivers a continuous flow rate of 10 Nm3/h in total autonomy.
