Your challenges

Corrosion of equipment

H2S is a corrosive component in biogas which can damage your utilization equipment for biogas. Our biogas desulfurization technologies remove up to 99% of H2S, improving the lifespan of your equipment.

Sustainability and carbon footprint goals

There is pressure to become more sustainable and to achieve certain sustainability goals. Biogas desulfurization ensures that energy recovered is not only renewable but also enables to burn the biogas in a correct way without harmful sulfur emissions.

Rising energy costs

Energy costs are continuously increasing, and there is pressure to adopt renewable energy. Using biogas is a sustainable way to lower your energy costs. Biogas desulfurization treats biogas and ensures it has the right quality, pressure and humidity for safe and efficient re-use.

How can NSI meet your needs?

Biogas treatment is used to prepare biogas to be re-used in boilers, generate electricity or to be injected in gas grids. The process of biogas treatment focuses on the removal of harmful components such as H2S and achieving the correct humidity, pressure, temperature and a stable flow. Examples of biogas treatment process steps that we offer are buffering, drying, compressing and cooling. In addition to this H2S or other unwanted substances can be removed.

High H2S removal rates

Our biogas desulfurization solutions achieve H2S removal rates of over 99%. In many cases, the biogas is ready for immediate use or requires only minor polishing with activated carbon filters – depending on your requirements.

Low operational costs

Due to the regeneration of washing fluid, little caustic is used compared to traditional scrubbers. This results in a lower OPEX, especially at higher sulfur loads.

Lower your natural gas use or any other energy source

Clean biogas, as a result of biogas desulfurization, can be used to generate electricity, heat or fuel. This allows you to become more self-reliant in regards to energy and lowering your dependence on natural gas or other energy sources.

Protects downstream equipment

By removing corrosive hydrogen sulfide (H₂S) and other contaminants, biogas treatment extends the lifespan of CHP units, boilers, gas engines, and pipelines. This reduces maintenance needs and prevents costly unplanned downtime.
