Reliable Core Technologies

A cut above competing biogas upgrading solutions. Our biogas upgrading’s core technology uses our proprietary PSA system, one of the most compact, economical, and reliable gas purification systems available today. The PSA’s unique fast-cycle rotary valve technology and advanced adsorbents are optimally designed to maximize methane recovery, even when levels fluctuate. Changes in feed impurity are automatically adjusted for continuously upgraded biogas production while consuming significantly less energy.

RNG Purity: 97+ %
Methane Recovery: 99.0+ %
Turndown: 40%-100% (Optional 20%-100%)
Capacity: 450 NCMH (280 SCFM) per Biostream container
