1. Waste‑to‑Energy Facility – Germany – Upgraded biogas to 99.5 % CH₄, feeding a 4 MW gas turbine. Result: 18 % OPEX reduction and 0.8 tCO₂e/ MWh saved.
2. Agricultural Digesters – Midwest USA – Modular 500 Nm³/h units installed on 10 farms. Result: 22 % increase in farm‑level electricity self‑consumption.
3. Municipal RNG Project – South Korea – Integrated PSA‑membrane hybrid, delivering pipeline‑grade biomethane. Result: Secured 5‑year off‑take contract worth $12 M.
“Enric’s biogas analyzer cut our commissioning time by 30 % and delivered methane purity of 99.6 % – exactly what our EU pipeline requires.” – Maria L., Procurement Manager, Shell
“The modular design let us scale from 200 Nm³/h to 4,000 Nm³/h without re‑engineering. ROI realized in 14 months.” – Thomas K., Operations Director, Siemens
Raw biogas from anaerobic digestion usually contains 55 %–70 % methane, with the remainder mainly CO₂, H₂S, N₂ and trace gases. Precise measurement is essential for sizing compressors and for upgrading efficiency.

Yes. Our dual‑stage sulfide scrubber removes up to 99.95 % of H₂S, tolerating inlet levels as high as 5,000 ppm. This protects downstream metal components and meets most national emission standards.
Pipeline‑grade biomethane must meet ISO 13628‑2, EN 12079‑2, and local gas‑grid standards (e.g., EU GTS). Our units are pre‑certified with ASME, DOT, CE, and ISO 9001, ensuring seamless integration.
Standard FOB shipment from Shijiazhuang reaches U.S. West Coast ports in 12‑14 days and EU ports in 10‑12 days. Express air‑freight of critical components is available within 5 days.
All contracts include a full‑service package: on‑site commissioning, 3 days of operator training, and a 12‑month warranty. Remote IoT support is available 24/7.
Limited‑time offer: Free 30‑day trial unit (up to 100 Nm³/h) for qualified purchasers. Stock is limited to 15 units per quarter.
