UGN and Green Gas Services, leaders in odor control, gas desulfurization, and gas upgrading technologies, have formed a strategic partnership to deliver integrated, high‑performance desulfurization solutions across North America. This collaboration brings together UGN’s proven media‑based hydrogen sulfide (H₂S) removal technologies with Green Gas Services’ field expertise, system integration capabilities, and customer‑focused operational support.
The partnership’s value is already visible at the Kompogas SLO plant by Kanadevia Inova, where their food waste-to-energy anaerobic digestion facility sought a reliable, low‑impact solution to remove H₂S from biogas and protect downstream equipment.
Challenge
The Kompogas SLO plant processes 250 cfm of biogas containing 250–450 ppm of hydrogen sulfide. To prevent corrosion in the CHP engine and meet operational and regulatory requirements, the facility needed a desulfurization system that was efficient, low‑maintenance, and environmentally responsible.
Solution
In 2018, UGN deployed the Bekom reactor paired with UgnCleanPellets®, an innovative, environmentally friendly adsorbent made from iron oxides and harmless compounds. The pellets remove H₂S through hybrid biological‑chemical reactions, offering a sustainable alternative to activated carbon.
System Highlights
- Vessel size: 10 ft × 11 ft height (177 ft3 usable volume)
- Pellet loading cycle: ~6 months per fill
- Annual media requirement: 175 ft3 (2.5–5 tons)
- Energy savings: 40–60% reduction in gas‑drying energy demand
- CO₂ reduction: 34–68 tons annually vs. activated carbon
- Automation: Fully integrated controls, oxygenator, condensate discharge, and a wetting system
As biogas flows through the reactor, H₂S is converted into elemental sulfur. The system’s design also cools and dehumidifies the gas stream, reducing downstream energy consumption and improving overall plant efficiency.
Impact
The Kompogas SLO installation demonstrates how the UGN–Green Gas Services partnership delivers:
- Higher performance through increased media loading capacity
- Lower operating costs via reduced energy use and longer media life
- Improved environmental outcomes with a dramatically smaller carbon footprint
- Greater reliability for RNG producers seeking to protect equipment and meet pipeline specifications
With RNG production expanding across North America, this partnership simplifies one of the most technically challenging steps in the process — effective, sustainable H₂S removal.
“We have been using UgnCleanPellets® since 2018 at our facility and they have delivered reliable H2S removal the whole time. The maintenance procedure is very straightforward and our downtime for media exchanges is minimal.”
