Brewery & Food Processing Biogas Recovery
HY-BON/EDI has completed eighteen successful installations capturing the methane biogas produced during the fermentation process of brewing beer. These installations in breweries across the U.S. and Mexico utilize this gas for heat and power generation – reducing the operating costs of the brewery while reducing pollution.
HY-BON/EDI has extensive experience capturing methane emissions from brewery and food processing operations. In breweries, methane produced during the fermentation process is captured and directed to electric generators, which then use the gas to provide a significant percentage of the brewery's power requirements.
Food processing applications include a large range of scenarios whereby methane gas is produced from decomposing materials. In a peach canning factory in California, a HY-BON/EDI vapor recovery system captures methane gas from decomposing peach skins. Our units capture methane gas from large storage containers in a chicken rendering plant in Alabama. As more companies investigate ways to reduce operating costs utilizing their waste streams and byproducts, the applications become as diverse as the food processing industry itself. In most cases, these previously vented gas streams are used to provide heat or electricity for the plant operations, insuring emission compliance and simultaneously reducing plant operating costs.
Landfill Biogas Recovery
Depending on the operator’s needs, HY-BON/EDI designs and builds compression systems configured for the economic capture of landfill gas that range from low pressure single stage units to medium pressure two or three stage systems.
Landfill operators in the US and across the globe are economically collecting gas produced by the landfill (LFG - Landfill Gas) during the decomposition of organic matter in the landfill. In many countried, including the United States of America, landfill gas (LFG) is no longer permitted to be vented to the atmosphere.
Typically the landfill gas (LFG) collection (recovery) system consists of wells being bored into the closed sections of the lanfill to relieve the landfill gas (LFG) pressure and to flow the gas to a manifold system. HY-BON/EDI's compressor systems (VRU - vapor recovery unit) collect the gas from the manifold and compress it to be used for several beneficial uses.
Lanfill gas (LFG) can be used in raw form to provide power for natural gas burning engine driven generator packages. These systems generate electricity which can supplement onsite electrical needs or can be sold into the power grid. Other landfill gas (LFG) systems are available in which the operator can actually clean up the landfill gas, with chemical systems, pressure swing systems or membrane systems, to pipeline grade quality.
Wastewater Treatment Biogas Recovery
HY-BON/EDI was a pioneer in the development of com-pression systems that could capture the vent methane from wastewater treatment facilities with their high water vapor content. HY-BON/EDI can provide both standardized equipment and highly specified designs for this application.
HY-BON/EDI is a leader in wastewater bio gas recovery, offering standard or custom designed packages to meet detailed customer specs. Our engineers draw upon over 50 years exerience with multiple industries to address the most challenging gas streams, providing integrated packages for wastewater treatment facilities in the US and around the world.
HY-BON/EDI - Midland, Tx. was instrumental in the development of specialized compressor packages for the capture and compression of highly corrosive vapors, such as those found in wastewater applications. These packages generally use a rotary vane compressor to take the vapors from a pressure of 2-3" WC to 40 psig or less discharge pressure. Compressed vapors are sent to one of three systems where they are used for a beneficial purpose. Typically, digester gas is used for one of the following:
2) steam generation
3) sewage sludge mixing or churning
