Biogas generated from landfills is gaining popularity as a sustainable source of renewable natural gas (RNG). Landfill biogas is usually contaminated with hydrogen sulfide (H₂S), oxygen, and water. Because H₂S and oxygen represent corrosion and safety hazards to natural gas pipelines, they must be removed from the produced gas before it can be sold as RNG.

EcoVapor provides your landfill gas operation with a comprehensive purification system for removing H₂S, oxygen, and water from your landfill gas streams so it can be sold as high-value RNG.

ZerO2™ – Remove Oxygen from Landfill Gas Streams

The ZerO2 solution removes oxygen contamination, enabling you to sell high-value RNG.

Advantages:

• Modular design to right-size capacity
• No moving parts for high reliability
• Small operational footprint makes ZerO2 units easy to move and install on location
• Non-toxic byproducts for sustainable and safe operations

Sulfur Sentinel™ – Cost-Effective H₂S Treatment

Sulfur Sentinel™ is an all-in-one solution for cost-effectively treating H₂S at landfill gas facilities. It uses a simple but highly effective dry iron oxide scavenger to safely remove hydrogen sulfide from the gas stream. This eliminates the complex equipment and scale inhibitors needed when using liquid chemicals. The spent iron oxide is easily and safely vacuumed from the vessel and disposed of in a local landfill without any special permits.

Advantages:

• Is a 100% self-contained solution requiring no changes to your existing processes
• Efficiently treats the specific H₂S concentration in your vapor stream, with no need to over treat to handle production stream variations
• Introduces no negative downstream process effects
• Eliminates scaling that results from the over-use of liquid scavengers
• Is highly reliable, with no moving parts and high uptime
• Eliminates the additional cost of scale inhibitor treatments
• Eliminates complex, failure-prone equipment associated with liquid chemical treatment
• Is environmentally friendly, producing compact, non-toxic waste
• Delivers Superior performance at a competitive cost
