MV Technologies – Iron Sponge H2S Scrubber

Company Description:

MV Technologies specializes in dry scrubber hydrogen sulfide removal systems for a broad range of industrial applications.

Their systems minimize maintenance costs for downstream equipment; help prepare gas utilization for renewable energy; enable air emissions compliance and eliminate odor.

MV Technologies designs both iron sponge based (H2SPlus™ Systems) and granular iron oxide based (SulfAx® Systems) for removal of hydrogen sulfide (H2S) from biogas.  MV Technologies also designs and OdorFilter™ Systems to remove H2S vapors and sulfur-based odors.

MV Technologies H2S removal solutions are designed to optimize media for safer, reliable and cost-effective performance.

Capex vs. Opex cost difference of both a SulfAx system vs. H2SPlus system vary. An MV engineer will help to identify the most cost-efficient solution to deliver against unique project requirements.

 

 

Technology Description:

 

MV’s core technologies are proven “dry scrubber” (aka., dry chemical adsorbent) 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.

There are two chemical reactions that take place in vessel:

  1. In the primary reaction, H2S in the inlet gas stream reacts with the iron oxide (FexOy) in the media to form iron-sulfur compounds (FexOy), free sulfur and water.

  2. Oxygen present in the gas stream further reacts with the iron-sulfur compound liberating the sulfur and re-forming the iron oxide, making it available once again for the primary reaction.

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.

Spent media is non-hazardous and can be land applied or disposed in a landfill.

 
Additionally, H2SPlus systems:
   
  • work anaerobically; with a very small amount of Oxygen to facilitate the reaction process.
  • do not require high pressure in order to operate like some other systems. This results in lower horsepower/electrical requirement.
  • economical sweet spot is between -2 to 8 psi. However, MV Technologies can design systems to operate at any pressure range. We would simple use our biologically-enhance granular media and adjust vessel size/type for psi 15 and above.
  • operates with no need for a water treatment system or sewer line access.
  • can be installed on either the ‘vacuum’ or ‘pressure’ side.

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.

Technology 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:

H2S Scrubbing Technology is required before most internal combustion engine generator sets:

  • Produces renewable low sulfur biogas by removing hydrogen sulfide and sometimes water vapor from biogas
  • Includes technologies such as iron sponge, biological treatment and chemical treatment
  • Used to treat biogas from an anaerobic digester
  • Most systems are technically complex
  • Not suitable for production of Renewable Natural Gas (RNG) and interconnection to the national gas infrastructure without further treatment (See Biogas Upgrading Technology)
  Newtrient will continue to work with MV Technologies to further refine the cost and performance information as more information becomes available and as new commercial dairy installations come on line.
