NGPGSolution for Concentration Detection of Biogas Recovery in Livestock Farms

1. Introduction

Farm biogas, as a renewable energy source, has significant value in resource utilization and environmental protection. However, fluctuations in methane concentration output and hydrogen sulfide concentration in biogas may lead to safety hazards or equipment corrosion, therefore a systematic concentration detection plan needs to be established. This plan combines domestic and international standards, technical means, and industry practices to propose a full process solution from testing equipment selection, deployment strategy to data management.

2、 Detection target

oMethane（CH₄）: Concentration Range0～100VOLReal time monitoring is requiredoutputConcentration.

oHydrogen sulfide（H₂S) Concentration: 0.1% -3%VOLIt is necessary to control to avoid equipment corrosion and personnel poisoning.

oCarbon dioxide（CO₂）: Concentration30%-50%%VOLAffects combustion characteristics.

oOxygen（O₂）The concentration should be lower than5%%VOLTo prevent the formation of explosive gas mixtures.

3、 Selection of Testing Equipment and Technology
