Roeslein's partner, a producer of packaged pork products, houses almost two million pigs that produce enough manure to generate 2.2 billion cubic feet of natural gas. According to the Roeslein Alternative Energy website, the companies are collaborating to convert this waste into renewable energy by trapping the biogas released from manure lagoons and storing it for a repurposed use--energy production.
ABUTEC designed a custom 1.5-megawatt enclosed combustor for the project that will burn off the excess waste gas that is not converted to energy, assisting in continued operation and production. The ABUTEC unit burns at a greater than 98 percent destruction and removal efficiency. Upon completion of the project, ABUTEC will ultimately manufacture 88 of these combustor units, one for each of their client's manure lagoons.
Roeslein selected ABUTEC's combustion technology to aid as a backup unit for their system. To customize the units for this project, ABUTEC had to consider the manure lagoons' Potential to Emit (PTE), possible corrosive contaminants within the gas composition and the functionality of its combustors with the Roeslein system.
"We were honored to be chosen as the flare supplier for Roeslein's innovative project," said Andy Smith, ABUTEC President and CEO. "Environmental sustainability is at the forefront of this project and aligns with ABUTEC's commitment to the reduction of harmful emissions."
Roeslein challenged ABUTEC to overcome the obstacles the company faced with previous flare designs they had employed, namely reliable ignition, continuous confirmation of combustion and highly efficient combustion to ensure no hydrocarbons were venting freely into the atmosphere. Resolving these issues was critical to moving forward with the project.
Roeslein will earn carbon credits for the reduction of the biogas emissions. A carbon credit, or carbon offset, is a form of compensation that represents one tonne of carbon dioxide removed or reduced from the atmosphere by an emission reduction project.
ABUTEC, an acronym for Advanced Burner Technologies, is a manufacturer of environmentally friendly combustion solutions. ABUTEC specializes in offering high-efficiency, low-emission burners and flares to various industries, including biogas, oil and gas (including upstream and midstream), landfill gas, wastewater treatment, mine gas and many more. ABUTEC manufactures burners, enclosed combustors/flares, vapor combustors, incinerators and thermal oxidizers, all aimed at reducing emissions and increasing efficiency.
