Biogas Monitoring & Analysis

Gas Data are regular contributors and active participants to ADBA and the WBA. The biogas market is on an upward trajectory and it is imperative to keep up to date with the latest developments in anaerobic digestion.

Our analysers can be used to expertly monitor and provide in-depth analysis metrics on the volume and composition of biogas.

What is biogas?

Biogas is produced in anaerobic digestors through the breakdown of food scraps, animal waste, and other organic matter by microorganisms in an environment that lacks oxygen.

The composition of biogas is largely made up of methane and carbon dioxide, however, it can sometimes include trace amounts of siloxanes, hydrogen sulphide, and some moisture; the amounts of these vary based upon the types of organic material that is being used to produce the biogas.

Where is biogas used?

With demand for renewable energy sources at an all-time high, biogas is the perfect alternative as it reduces our reliance on finite fuel resources to generate electricity such as natural gas and coal. Using biogas as an energy source will also reduce the greenhouse gas emissions attributed to the decomposition of organic and food wastes.

Leftover digestate from the anaerobic digestion process is used as an organic fertilizer which is an excellent alternative to chemical fertilisers. Using digestate contributes to a circular economy in crop production and removes potential damage to surrounding habitats – maintaining the biodiversity of farmlands.

Why monitoring biogas is essential

The production of biogas involves four successive degradation processes; hydrolysis, acidogenesis, acetogenesis, and methanogenesis. If one these processes is, in any way, negatively affected there can be an immediate impact on the others and the biogas plant can become unstable.

Biogas monitoring can help to provide a greater understanding of what is happening in the plant and aid in maintaining stability. Additionally, the costs of monitoring are often significantly lower than the revenue that is lost when re-establishing a destabilised plant.

Why Gas Data instruments?

Gas Data biogas analysers benefit the user in 3 areas: Safety, Maintenance, and Research. Gas Data products log data locally to be uploaded to a network for further analysis and trend mapping – with fixed systems able to stream data directly to the Gas Data Portal.

This is an invaluable asset to maintain safety and efficiency on site, whilst giving those with experimental processes the capability to trace the effectiveness of their trials.

A large proportion of Gas Data equipment is deployed on biogas sites globally. Gas Data supply analysis equipment to AD Plants running CHP Engines, those tracing the effectiveness of their desulphurization apparatus, and sites observing outputs when experimenting with feedstocks.
