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.

Meat Processing Lagoon Digester, Texas

Application:

The facility installed a new digester to pre-treat the wastewater from the processing plant. The gas from the digester is required to be treated to below 400 ppm prior to being burned in the on-site boiler.

MV Solution:

MV provided a three-vessel H2S plus system configured with an H2S analyzer on the outlet gas and a modulating gas bypass valve. The system maintains a 400 ppm H2S outlet in order to meet the specification but also extend the bed life of the iron sponge media.

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. .
