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, methane in biogasConcentration output andThe concentration fluctuations of components such as hydrogen sulfide 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

o Methane (CH)?）: Concentration range 0%～100VOLReal time monitoring is requiredoutputconcentration.

o Hydrogen sulfide (H)?S) : Concentration 0.1% -3%VOLIt is necessary to control to avoid equipment corrosion and personnel poisoning.

o Carbon dioxide (CO)?）Concentration: 30% -50%%VOLAffects combustion characteristics.

o Oxygen (O)?）The concentration should be below 5%%VOLTo prevent the formation of explosive gas mixtures.

3、 Selection of Testing Equipment and Technology

1. Online monitoring system
