Meets Standards:
Project: 5 MW Landfill Gas-to-RNG
Results:
“The membranes handled high H₂S levels (3,000 ppm) without degradation. Zero failures in 24 months.”
— Mark Johnson, Plant Manager
Project: 10 MW Agricultural Biogas Upgrading
Results:
“Certified for injection into the German gas grid (DVGW G 260). No methane slip detected in 18 months of operation.”
— Klaus Schmidt, Technical Director
| Biogas Source | Methane Content | Enric Membrane Performance | Typical Plant Size |
|---|---|---|---|
| Landfill Gas | 45-60% | 99.8% CH₄ purity, H₂S-resistant | 1-10 MW |
| Agricultural (Manure) | 50-75% | 99.9% CH₄ purity, low fouling | 0.5-5 MW |
| Wastewater Sludge | 55-70% | 99.7% CH₄ purity, humidity-tolerant | 0.1-2 MW |
| Industrial Waste | 60-80% | 99.9% CH₄ purity, high flux | 2-20 MW |
“Biomethane production is projected to grow 15% annually through 2030, with membrane separation as the fastest-growing technology.” — Fortune Business Insights, 2025
Our membranes are guaranteed for 5 years under normal operating conditions (≤80°C, ≤10 bar, <5,000 ppm H₂S). In real-world applications, 70% of clients exceed 6 years with proper maintenance. Compare this to competitors’ 3-4 year ratings.
Yes. Our ENRIC-GM-2026 membrane is optimized for 30-70% CO₂ feed gas. At 50% CO₂, it achieves 99.5% rejection with a methane recovery rate of 98%. For higher CO₂ levels, we offer multi-stage configurations.
| Factor | Membrane | Water Scrubbing |
|---|---|---|
| Methane Purity | 99.9% | 98-99% |
| Chemical Use | None | High (water + additives) |
| Wastewater | Minimal | High (requires treatment) |
| Energy Use | 0.20 kWh/Nm³ | 0.25-0.30 kWh/Nm³ |
| Footprint | Compact | Large (tall columns) |

Biogas Plant Manager, Texas USA
“We replaced our amine scrubber with Enric’s membranes 2 years ago. Savings: $1.2M/year. The best part? No more chemical handling—our safety incidents dropped to zero.”
⭐⭐⭐⭐⭐
RNG Project Developer, France
“Certified for French grid injection on the first try. Other suppliers required costly pre-treatment—Enric’s membranes handled our raw landfill gas directly.”
⭐⭐⭐⭐⭐
Director, Green Energy India
“Delivered in 8 weeks—half the time of EU suppliers. The anti-fouling coating works: no cleaning in 18 months. Highly recommend for high-H₂S biogas.”
