Dairy Farm Anaerobic Digester, California

Application:

The facility installed a new H2S scrubbing system to treat the biogas produced from their dairy farm. The gas was required to be treated to 10 ppm.

MV Solution:

MV provided a two-vessel configuration of our SulfAx™ System operated in lead-lag. This system, containing 44,000 lbs. of our enhanced granular media, delivers a maximum H2S outlet concentration of 10 ppm.

Cheese Processing Facility, Wisconsin

Application:

The facility installed a new H2S scrubbing system to treat the biogas produced from their cheese processing operation. The gas was required to be treated to below 50 ppm.

MV Solution:

MV provided a single-vessel configuration of our H2SPlus™ System. This system, containing our enhanced iron sponge media, BAM™ Media, delivers a maximum H2S outlet concentration of less than 50 ppm, under the stated current operating conditions.

Dairy Digester, Idaho

Application:

A leading biogas developer, approached MV Technologies for a system to reduce the total hydrogen sulfide concentration in a biogas stream from a 15,000-head manure-based digester. The system was required to meet the facilities air emissions permit requirements. Generating 4.2MW, the digester H2S concentration can fluctuate from 800-1,000 ppm.

MV Solution:

A single-vessel H2SPlus System treats a portion of the gas to reduce the amount of H2S to comply with the facility’s air permit. Originally the operator of the system treated only enough biogas to comply with the air permit. They found their engine maintenance cost decreased as they increased the amount of biogas treated. The increased media cost was more than justified by the decreased maintenance cost. This facility is considering system expansion and may add a second vessel to their H2SPlus System to treat more of the gas flow and deliver less sulfur to the engines. .

Yogurt Dairy Digester, New Hampshire

Application:

A digester on-site at a dairy food processing farm treats facility wastewater consisting mostly of wash water and chemicals from cleaning food processing equipment. An H2S removal system was needed to treat the gas for a micro turbine. In addition the biogas can also be combusted in a boiler.

MV Solution:

MV Technologies worked directly with the client to develop a customized vessel configuration to accommodate the specific flow rate and H2S concentrations expected from the digester. The facility has realized a significant reduction in the boiler maintenance after the installation of this system.
