Optimized Biogas Upgrading at Eastern Ohio WWTP: GraniteFuel Engineering’s Integrated Single-Skid Solution for Sustainable Electricity Generation
GraniteFuel engineering on display to fit all equipment on single skid allows for simple on-site construction, installation, and commissioning biogas is boosted twice by GraniteFuel system; once for low-pressure treatment and a second time to feed a 100 kW microturbine.
GraniteFuel Engineering’s cutting-edge biogas upgrading equipment has revolutionized the Eastern Ohio Southerly Wastewater Treatment Plant (WWTP) operated by the Eastern Ohio Regional Wastewater Authority (EORWA). This installation highlights the significant impact of GraniteFuel Engineering’s equipment, including H2S removal, low-pressure blower system, dehydration, activated carbon scrubbing, and biogas compression. By utilizing these advanced technologies, the WWTP has successfully transformed biogas into clean electricity through a 100 kW microturbine, enabling sustainable energy generation and environmental stewardship.
Project Overview:
GraniteFuel Engineering provided a custom biogas conditioning system designed to fit all equipment on a single skid, ensuring simplified on-site construction, installation, and commissioning. The system incorporated multiple components, including H2S removal, a low-pressure blower system for boosting biogas treatment, biogas dehydration to remove moisture, activated carbon scrubbing for impurity removal, and biogas compression to feed the waste to energy (w2e) process. This comprehensive solution aimed to optimize the quality and efficiency of biogas for electricity generation.
Impact on Electricity Generation:
By leveraging GraniteFuel Engineering’s biogas upgrading equipment, the WWTP achieved remarkable results in electricity generation. The biogas, boosted twice by the GraniteFuel system, underwent thorough treatment to ensure optimal gas quality. The first boost prepared the biogas for low-pressure treatment, while the second boost delivered it to a 100 kW microturbine. The wastewater treatment process requires a great amount of energy, so an efficient gas to electricity process was vital. This turbine effectively converted the upgraded biogas into clean and renewable electricity, reducing the facility’s reliance on conventional power sources, minimizing its carbon footprint, all while serving over 530,000 residents with an average flow of 120 million gallons per day.
Environmental and Economic Benefits:
The implementation of GraniteFuel Engineering’s biogas upgrading equipment brought forth numerous environmental and economic advantages. Firstly, the removal of H2S and other impurities improved the overall quality and purity of the biogas, minimizing emissions, improving energy density, and enhancing environmental compliance. The generation of clean electricity from biogas showcased the EORWA’s commitment to sustainability and renewable energy production.
Moreover, by utilizing biogas for electricity generation, the WWTP experienced significant cost savings and reduced energy expenses. The reliable and efficient operation of GraniteFuel Engineering’s equipment resulted in improved energy efficiency, reduced downtime, and enhanced performance of the microturbine system. This not only decreased operational costs but also provided a reliable and sustainable source of electricity for the facility.
The implementation of GraniteFuel Engineering’s single skid design for biogas conditioning equipment had significant operational benefits for the Wastewater Treatment Plant (WWTP). By consolidating all the necessary equipment onto a single skid, the design has simplified on-site construction, installation, and commissioning processes. This streamlined approach has not only reduced the complexity and time required for system setup but has also enhanced overall operational efficiency. The compact and integrated design has optimized space utilization and improved accessibility for maintenance and troubleshooting activities. This single skid solution reduced time and costs thanks to convenient installation, ensuring a seamless and efficient operation of the biogas upgrading equipment.
Conclusion:
GraniteFuel Engineering’s biogas upgrading equipment has made a transformative impact on the Eastern Ohio Regional Wastewater Treatment Plant, enabling the conversion of biogas into clean electricity. Through the comprehensive system, encompassing H2S removal, low-pressure boosting, dehydration, activated carbon scrubbing, and gas compression, the WWTP has achieved significant environmental benefits while realizing substantial cost savings. By partnering with GraniteFuel Engineering, the EORWA has become a pioneering force in sustainable wastewater management, showcasing the potential of biogas utilization for clean, renewable energy generation.
