01 Overview
How do adsorbents upgrade biogas and capture CO₂?
PSA and VPSA units separate CO₂ or nitrogen from methane without solvents: CO₂ Adsorbent Molecular Sieve removes CO₂ from biogas and landfill gas, while Molecular Sieve for Methane Enrichment removes nitrogen from low-grade methane. The same principle captures CO₂ from dried process and flue gas.

03 Challenges
What makes biogas upgrading difficult?
Four problems that decide methane yield and adsorbent life.
H₂S and siloxanes
They damage adsorbents and engines and must be removed upstream.
Water in the feed
Water is held far more strongly than CO₂.
Methane slip
Methane lost with the tail gas lowers yield and adds emissions.
Variable feed
Digester and landfill gas change in flow and composition.

08 From our plant
What you receive
The adsorbent, the packing and the plant it ships from.
Does biogas need pretreatment before the CO₂ sieve?
Yes — remove H₂S, siloxanes and moisture upstream.
How does the CO₂ adsorbent regenerate?
By pressure or vacuum swing every cycle; thermal reactivation at 250–300 °C only after water ingress.
Which sieve removes nitrogen from methane?
Molecular Sieve for Methane Enrichment takes up nitrogen far faster than methane in a short PSA cycle.
Can you supply pilot quantities?
Yes, samples from 5–10 kg.
