Hydrogen Sulfide (H₂S)
About
Companies in industries including waste management and biogas production need reliable solutions to treat H₂S and safeguard their business, employees, and neighbors. DESOTEC’s full-service mobile filtration solutions cover everything from analysis to waste handling, protecting machinery and human health.
What Is Hydrogen Sulfide?
Hydrogen sulfide results from the breakdown of organic matter through anaerobic digestion. Even at low concentrations, its distinctive rotten egg smell causes odor nuisances. Sewage and sludge at wastewater treatment plants (WWTPs) and rotting green refuse at waste management sites are common sources of H₂S emissions.
Apart from having a foul smell, H₂S is toxic, posing a serious occupational health risk. When reacting with water, H₂S turns into sulfuric acid, which is corrosive. It’s also flammable. For this reason, it’s a priority for companies to find effective methods for removing H₂S and disposing of it safely.
DESOTEC is ready to help, supporting your company with our full-service sustainable mobile filtration solutions. Because H₂S is inorganic, we use specially impregnated activated carbon to chemically adsorb it onto our filters.
Hydrogen Sulfide Odor Control
Nobody wants to live near or work at a facility that emits a sulfur smell. Sites where H₂S is unavoidable, such as WWTPs and biogas production plants, must treat odor emissions to maintain good community relations, protect their reputation, and continue to do business.
Because H₂S is often emitted together with other components, the mixture treatment can require more than one technology, or multiple filters in series. Scrubbers, for example, can be used to remove the bulk of the contaminants before the gas stream is passed through the DESOTEC filter as a polishing step. The result is clean, fresh-smelling air.
DESOTEC’s sustainable mobile filtration services for odor removal can be situated at many other emissions sources, such as vents from tank storage. Our filters can handle discontinuous flows, which means the filters work well for applications such as truck loading.
Biogas Purification
Odor emissions are not the only problem that DESOTEC’s filters can solve. In biogas production plants, H₂S corrodes machinery such as combined heat and power (CHP) engines. H₂S can also damage the membranes used for biogas upgrading to biomethane.
Here, as well, scrubbers might treat the bulk of the contaminants before activated carbon filters remove the residual molecules. DESOTEC installs filter setups designed for each unique site, such as separate filters containing various carbon types for volatile organic compounds (VOCs) and H₂S removal.
Hydrogen sulfide (H₂S) is a naturally occurring gas. Due to its sulfur smell and health effects, H₂S industrial emissions must be controlled. DESOTEC’s mobile filtration services can help you leave the air breathable and odor-free.
Helping you comply
DESOTEC’s sustainable mobile filtration services enable your company to comply with stringent air quality and occupational health legislation. Due to the toxicity and flammability of H₂S, site operating licenses set out very low limits, which makes polishing with activated carbon filtration is often essential.
If odor complaints prompt action required by the environmental authorities, DESOTEC can quickly install filters that will take effect immediately.
In biogas and biomethane production, manufacturers set limits for how much H₂S their CHP engines, membranes or other equipment can handle. DESOTEC filters enable you to abide by this guidance, protecting your machinery and saving on maintenance costs.
How we help you
DESOTEC Sustainable Mobile Filtration Solutions
DESOTEC’s full-service solutions allow your company to focus on its core business.
Our activated carbon filters are easy to install and replace, requiring no production downtime. We have filters suitable for a range of flow rates, concentrations, and other process parameters.
Waste handling is part of our service. We have the expertise and equipment to manage H₂S safely, transporting it in closed units away from your site; the spent carbon is sent for safe disposal and valorization. Our R&D team is continually working on ways to further boost sustainability.
DESOTEC helped us upgrade our biogas stream, making it usable in the main gas grid. Thanks to their flexible solution, we were able to adapt quickly.
Biogas Impurities? Learn How to Remove Them!
The production of biogas and biomethane is an important green energy source. However, biogas and biomethane often contain impurities, such as H2S and VOCs, which negatively affect the gas quality or damage your equipment. This e-book explains how activated carbon filtration solutions can purify pollutants in biogas and biomethane plants.
