Sulfur Sentinel™ is an all-in-one H2S Gas Treating solution for cost-effectively treating H2S at oil and gas well sites. 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.
Our Dry Iron Oxide Scavenger is the “solid” and simple solution to sour gas treatment to protect equipment and pipe.
Sulfur Sentinel H2S Treatment Solution for Oil & Gas:
- 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
Sulfur Sentinel for Biogas
Sulfur Sentinel™ is an all-in-one solution for cost-effectively purifying biogas and landfill gas (LFG) feedstocks of H2S.
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 as a non-hazardous waste.

EcoVapor manages the entire H2S Gas Treating Solution, including vessel delivery and installation, scavenger loading, periodic monitoring, performance measurement, catalyst change-out and disposal of the spent scavenger.

Sulfur Sentinel Webinar
Representatives from EcoVapor and Mesa Applied Technologies discuss the findings of a case study, covering the economic and operational benefits of a Sulfur Sentinel installation with an E&P operator. Key results include a 75% reduction in H2S treatment costs with a one-month payout.
For E&P companies seeking a simple and cost-effective method for treating H2S, Sulfur Sentinel delivers an all-in-one solution, including the vessel, media, installation, maintenance, media replacement and disposal. Sulfur Sentinel’s solid media is non-hazardous and has no hidden costs associated with corrosion or downstream process effects.
