MV’s H2SPlus™ Systems are in use treating biogas streams from landfills to anaerobic digesters at farms, wastewater treatment facilities and food & beverage processing operations. MV’s systems treat 30,000 cubic feet of biogas and landfill gas/min., every day and provide low cost solutions to H2S management in natural gas production and oil refining operations.Click here to read more about H2S removal options, by applications
H2SPlus Systems are designed to remove low to moderate concentrations of hydrogen sulfide (H2S) and mercaptans from gas and air streams. In addition to the removal of sulfur-containing products, the system also will remove certain biodegradable, volatile, and semi-volatile hydrocarbon odors, together with amine odors.
The basic H2SPlus System is a result of over ten years of in-field application and each component is sized to meet site-specific requirements. Systems can be easily configured to adjust to future changes (+/-) in process operating parameters.Key components of an H2SPlus system are:
There are standard inputs required to properly size an MV H2SPlus™ system:
The flow rate information determines the size and number of media tanks required. Geographic location determines if the tanks need to be insulated. The concentration determines the media consumption rate and informs other elements on the design of the system. The combination of the flow rate and the concentration yields the weight of H2S to be removed per unit time. You can estimate your annual H2S treatment requirements and media consumption cost here.
We also need to know the intended use of the gas after it has been scrubbed. If it is intended for pipeline application or other uses that demand strict controls over concentrations, those will influence the system design as well. Media life between replacement cycles is calculated based on the H2S concentration, total flow rates, and specific system design.
The final design selection is often a trade-off between system footprint limitations and target media change cycle time.Request A Quote
MV’s core technology is its H2SPlus™ Systems – a proven “dry scrubber” (aka., dry chemical (absorbent) scrubber technology combined with a superior system design – informed by over ten years of in-field application to ensure maximum performance, safety and cost-effectiveness.
The H2SPlus™ System approach to dry-scrubbing uses long-proven, low-cost iron oxide coated media (iron sponge) that MV Technologies has enriched with select bacteria and complemented with a system designed to extend media life and dramatically increase ease of system use. Iron sponge has been used to remove H2S from gas streams for more than 100 years and the media is comprised of wood chips coated with iron hydroxide.
H2SPlus Systems are currently in use throughout the U.S. treating a variety of gas streams to remove H2S & mercaptans and reduce SO2.
These regeneration reactions require oxygen which may naturally be present in the gas stream or (a small amount) can be added by air injection at the scrubber. In the event that outlet gas conditions do not accommodate air addition, the secondary regenerative reactions can be performed “off-line” by taking the vessel out of active service.
Additionally, H2SPlus systems:
NOTE: it is advantageous to install H2SPlus on the ‘vacuum side’ when possible since such a design may offer potential total system performance advantages such as protecting more system components from H2S exposure, reducing total system horsepower consumption and possibly reducing capacity requirement on other system elements.
MV applies the best available technology to clients’ site specific conditions in order to deliver H2S removal systems at the lowest total cost of ownership with a performance guarantee to meet target outlet concentration.
H2SPlus Systems are Performance-Based.
H2SPlus Systems are guaranteed to meet target outlet concentrations, regardless of seasonal variations / fluctuations of H2S inlet ppmv. An increase in H2S concentration only affects the rate at which the media is consumed and not the performance of the system. And, at $1.31 per pound of neutralized H2S -- our enhanced iron sponge media, coupled with our engineered systems, provides the most economical dry scrubber in-market.
Importantly and unlike biological scrubbers, an H2SPlus Systems will absorb large fluctuations of incoming H2S concentrations, and continue to deliver the designed outlet condition without deviation. Therefore, if your project has a “bright-line limit” on H2S or SO2 concentrations, there is no need to worry about whether changes in feedstock, water conditions, or any other incoming variable will put you out of compliance when using the H2SPlus System.
Additionally, it is important to point out that MV modifies commercially available iron sponge and markets it as B.A.M. (bio-active media). MV purchases standard grade iron sponge product from a commodity supplier, and enhances that material with biological agents to produce a more reactive and effective media. The iron hydroxide in the B.A.M., neutralizes the H2S by converting it into iron sulfide compounds through chemical reaction, and the bacteria serve to “refresh” the available reactant. MV’s addition of biological agents to media result in removal of numerous non-sulfur bearing species such as VOC’s and readily biodegradable organic compounds, and improved re-oxidation of the iron sulfide compounds (troilite and pyrite) to regenerate iron oxides for subsequent reactions. All of this adds up to extended life of the reactive media and lower cost of operation.
Note: MV does not sell B.A.M. for application in other dry scrubber equipment installations. The total performance that we secure from our media is in part driven by the specific engineering elements of the H2SPlus system design and it is the combination of the two that enable MV to offer its MV Performance Guarantee.
What sets H2SPlus Systems apart from other systems is the combination of biologically enhanced media with a proven system design, informed by over ten years of in-field application.
