Lean Gas To Power
Lean Gas To Power
The Lean Gas To Power (LG2P) system is designed to convert landfill gas, particularly low-methane concentration gas, into valuable energy while minimizing greenhouse gas emissions. This technology supports environmental sustainability by transforming waste into a resource and reducing the carbon footprint of landfills.
Main Features
- Eliminates greenhouse gases by reducing CH₄ content to less than 0.2% after oxidation.
- Avoids combustion by-products like NOx and SOx due to low-temperature oxidation.
- Compact design with a standard 40-ft container footprint, offering cost and space savings compared to biofilters.
- Recovers all possible gas from landfills using suction, preventing leakage.
- Suitable for lean gas with CH₄ as low as 1.5%.
- Produces 130 kWe with 50 Sm³/h of methane and 340 kWt at 240°C.
- Utilizes a proprietary advanced oxidized catalyst with an 8000-hour lifespan without regeneration.
Benefits
- Transforms waste into a resource while preventing greenhouse gas emissions.
- Enhances the value of low-methane concentration landfills.
- Provides dual benefits by removing pollutants and generating energy.
How It Works
- The compressed gas stream is sent into a catalytic chamber for oxidation at 750/800°C, resulting in negligible NOx/SOx emissions.
- Gas is collected from the landfill by suction, maximizing methane recovery.
- The re-heated flow passes through a turbine connected to a high-speed generator to produce power.
- The exhaust gas is sent to a heat exchanger to generate thermal power.
System Design
- Includes components such as air dilution mixer, air intake, compressor turbine, catalytic oxidation chamber, heat exchanger, and high-speed generator.
- Handles a typical lean gas composition with CH₄ content less than 10%.
- Mass balance and flow rates are optimized for efficient energy production.
Technology Map
- Advanced exhaust gas cleaning systems including DeSox, DeNOx SCR, and diesel oxidation catalyst.
- Pre-treatment and upgrading technologies like smart blending and biogas upgrading.
- Carbon capture and sequestration methods including scrubbing and liquefaction.

How It Works THERMAL POWER HEAT EXCHANGER CATALYTIC OXIDATION CHAMBER ELECTRICAL POWER HIGH SPEED GENERATOR TURBINE Gas is collected by suction from the landfill, avoiding any leakage of greenhouse gas and exploiting all the methane available thanks to vacuum. The compressed stream is sent into the catalytic chamber for oxidation (750/800 °C - negligible NOx/SOx). The re-heated flow passes through a turbine directly connected with the high-speed generator to produce power. The exhaust gas is sent to a heat exchanger to generate thermal powe
