Projects Updates/The Results
InnoSepra's gas conditioning system was upgraded and delivered to the Simi Valley landfill in September, 2018. The system has been functioning as designed, and the project team has focused on accumulating hours of operation. InnoSepra was unable to make a second deployment at a digester site due to time constraints. The outcome at the landfill site shows that the absorption process is capable of upgrading landfill gas with up to 200 ppm hydrogen sulphide to renewable natural gas. Economic modeling suggests that the temperature swing regeneration will reduce process power consumption by 50%, resulting in significant cost reduction compared to alternative processes (amine absorption, membranes, pressure-swing absorption).
This project deployed a pre-commercial technology demonstrating a sorbent-based biogas purification process for combined heat and power generation at the pilot scale that removes multiple troublesome impurities from biogas, upgrading the fuel to near-pure methane for combustion in conventional prime movers. The pilot plant was installed and tested at a landfill site to demonstrate the environmental and cost benefits of biogas purification prior to use in combined heat and power applications.
This project is expected to lower costs by reducing the number of stages required to condition biogas to meet fuel specifications of most prime movers.
Environmental & Public Health
The project will reduce carbon dioxide emissions by increasing the use of renewable fuel and replacing fossil-derived methane for electricity generation. The project will also result in fewer methane emissions by reducing the fla
