Biogas from landfills and digestion plants often contains very high levels of water vapor. This moisture poses a serious challenge for reliable gas analysis and can damage sensitive instrumentation. Traditional chillers struggle to cope with such high moisture loads, especially under extreme temperature or humidity conditions. The result can be inaccurate measurements, corrosion, and costly equipment failures.
Perma Pure offers an innovative solution through Nafion™ membrane technology. This unique polymer selectively and rapidly removes water vapor without affecting key gases such as methane, oxygen, and carbon dioxide. The process takes place within milliseconds and prevents condensation or spectral interference. This ensures both accurate measurements and long-term protection of analyzers and sensors.
For landfill and biogas applications, several options are available. The PD Series dryers are ideal as a “polisher” placed after an existing chiller to remove residual moisture. Compact solutions such as the MiniGASS and the Hybrid Cooler provide robust performance even under high-moisture conditions. The result is a more stable gas stream, more accurate analyses, and improved protection of valuable equipment.
With Perma Pure, operators of biogas facilities can rely on consistent measurement results, reduced maintenance, and lower operating costs. Where traditional methods fall short, Nafion™ technology makes the difference.
