EcoVapor – Sulfur Sentinel

Renewable Natural Gas (biogas) H2S Purification Solution

About the Company:

EcoVapor is dedicated to helping producers of Renewable Natural Gas (RNG) achieve environmental and economic goals with innovative technology.

Originally developed to help oil and gas producers improve environmental performance while generating additional profits, EcoVapor units are working today to purify natural gas production streams in every major oil-producing region in America to eliminate routine flaring and minimize emissions while maximizing productivity and profits. Now, they are taking their proven gas purification technology to the RNG/Biogas market.

In practice EcoVapor’s scalable yet flexible purification products are an effective solution for bringing biomethane to market.

Since 2010 EcoVapor has been stiving to achieve these goals while adhering to their guiding principles of integrity, efficiency, innovation, and positive environmental impact.

About the Solution:

The composition of biogas varies widely, but typically includes methane, carbon dioxide, hydrogen sulfide (H2S), water vapor, and oxygen. Hydrogen sulfide and oxygen create corrosion and safety hazards to infrastructure, including natural gas pipelines. To sell biogas as renewable natural gas (RNG), it must be purified to meet pipeline specifications by removing water, H2S and oxygen.

EcoVapor’s Sulfur Sentinel is the "solid" and simple solution for H2S treatment to protect equipment and piping and deliver biomethane at pipeline specifications.

Sulfur Sentinel is an all-in-one solution for cost-effectively treating biogas contaminated with H2S. It uses a simple but highly effective dry iron-based 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-based media is easily and safely vacuumed from the vessel and disposed of in a local landfill without any special permits.

Advantages of EcoVapor’s Sulfur Sentinel H2S Treatment solution:

  • 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

    Solution Strengths, Weaknesses and Critical Indicators

    Anaerobic Digester Associated Technology:

    NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.


    • Long usable life and can be run reliably
    • Creates energy and generates environmental credits
    • Requires proper preparation of the feedstock
    • Requires other technologies for energy utilization
    • Requires other technologies for digestate handling
    • Proper feeding & system monitoring is required to avoid system downtime
    • Proven technology for odor control, GHG reduction and pathogen reduction

    Newtrient Comments/Opinions:

    EcoVapor has recently been added to the Newtrient catalog. Newtrient will continue to work with EcoVapor to further refine the cost and performance information on their solutions. Newtrient will update this entry as more information becomes available and as new commercial dairy installations come online.
