Enhancing Clean Energy Production: GraniteFuel’s Biogas Upgrading Solution at London Biogas Facility
The London Biogas Facility, situated in London, Ontario, stands as a shining example of sustainable waste-to-energy practices. Tasked with the challenge of efficiently upgrading biogas derived from a Source Separated Organics (SSO) digester, the facility collaborated with GraniteFuel Engineering to implement cutting-edge biogas upgrading equipment. This case delves into the intricacies of the project, highlighting the tailored solution provided by GraniteFuel, the advanced technology employed, and the profound impact on clean energy production.
Biogas From Source Separated Organics (SSO)
Source Separated Organics (SSO) derived biogas refers to the methane-rich gas produced through the anaerobic digestion of organic materials that have been segregated from other waste streams. SSO specifically involves collecting organic waste, such as food scraps and yard trimmings, separately from general waste. This separation allows for efficient processing and anaerobic digestion of these organic materials, resulting in the production of biogas. SSO derived biogas is a valuable renewable energy source that can be upgraded and used as a clean and sustainable fuel for various applications, contributing to waste diversion and reducing greenhouse gas emissions.
Upgrading Source Separated Organics (SSO) derived biogas to Renewable Natural Gas (RNG) offers a multifaceted value proposition. Rich in methane content, SSO biogas, when upgraded, becomes a sustainable source of renewable energy that mitigates landfill methane emissions and reduces reliance on non-renewable fuels. The process aligns with waste diversion objectives by repurposing organic waste, while the resulting RNG can be used locally, enhancing energy security. As a green fuel for natural gas vehicles, RNG curtails emissions and improves air quality. Injected into gas pipelines, it augments the sustainability of conventional natural gas supplies. By converting SSO waste into RNG, communities foster energy independence, contribute to a greener energy mix, and align with environmental and sustainability goals.
Project Details
With a gas flow of 705 standard cubic feet per minute (scfm), the London Biogas Facility sought to address the issue of Volatile Organic Compounds (VOCs) present in the biogas generated from the anaerobic digestion of food waste. VOCs, when left untreated, could potentially compromise the integrity and performance of downstream equipment, such as the membranes used in Renewable Natural Gas (RNG) systems. To tackle this challenge, GraniteFuel Engineering offered a state-of-the-art solution: a Temperature Swing Absorption (TSA) system designed to efficiently remove VOCs and enhance the quality of the biogas.
Innovative TSA Solution
GraniteFuel’s TSA system was strategically retrofitted into the London Biogas Facility’s setup, targeting the removal of VOCs from the biogas stream. Unlike conventional static media solutions like activated carbon, the TSA system offers a more economical and effective means of removing VOCs. This dynamic solution not only optimizes the quality of the biogas but also ensures the smooth operation of downstream equipment, a critical factor for the facility’s overall efficiency.
Efficient VOC Removal
The collaboration between GraniteFuel and the London Biogas Facility illustrates the power of innovative engineering in the realm of renewable energy production. By addressing the challenge of VOCs in the biogas stream, GraniteFuel’s tailored solution has not only enhanced the quality of the biogas but also minimized the potential for equipment damage. As a result, the London Biogas Facility can confidently rely on the clean biogas as a valuable energy source, contributing to Ontario’s sustainable energy landscape.
Harnessing the Potential of Biogas
The success of the London Biogas Facility’s collaboration with GraniteFuel Engineering serves as a testament to the transformative potential of advanced biogas upgrading solutions. Through the implementation of the TSA system, the facility not only efficiently removes VOCs but also paves the way for the optimized performance of downstream equipment. This case study exemplifies the critical role that innovative engineering plays in propelling the adoption of renewable energy and sustainable waste management practices. By aligning environmental responsibility with cutting-edge technology, the London Biogas Facility and GraniteFuel Engineering contribute to a greener and more sustainable energy future.
