Biogas Sampling & Analysis Services

Renewable Natural Gas (RNG), also known as biomethane, biogas, or renewable methane, is an increasingly important part of the U.S. clean energy future. When it comes to sampling, RNG comes with complex challenges. The biogas experts at Alliance Technical Group are not only here to help you understand your RNG sampling and analysis requirements, but to also help you develop solutions.

What are the challenges?

  • The biogas must meet state gas tariff requirements to be considered pipeline quality.
  • To meet the pipeline’s specifications, the product gas and other sample points are routinely sampled and analyzed.
  • Initial testing requirements for biomethane can be rigorous and complex.
  • Testing requires specialized methods, equipment, laboratory analysis and experienced sample technicians.
  • Onsite Moisture can cause serious issues—certain tests require specialized equipment for sampling.

Typical Analysis Needed

  • H2S
  • VOC
  • Sulfur
  • CO2/O2
  • Metals
  • Pesticides/PCB
  • Siloxanes
  • Ammonia
  • Mercury
  • Biologicals
  • Onsite Dewpoint &
  • Moisture

How Alliance’s experts can help

  • We work with the waste facility and pipeline company to help interpret the sampling and analysis requirements.
  • Our analysis capabilities can meet specialized, onsite needs-for example Water Dewpoint, Hydrocarbon Dewpoint, and Moisture Content (lbs/MMscf).
  • We can help determine if a comprehensive baseline test is required or if a less expensive and demanding test plan will satisfy the gas company.
  • Our experts will handle all the sampling needs efficiently in 1-2 days.
  • We can manage the entire process from start to finish including the sampling, laboratory analysis, and interpretation and reporting of results.
  • Subsequent testing may be required after the first baseline test comes back. Alliance can help develop a regular test plan and sampling event calendar, so the customer doesn’t have to.
