Techno-Economic Assessment of a Gasification Plant for Distributed Cogeneration in the Agrifood Sector

This research work presents a techno-economic analysis of biomass gasification plant fueled with residues from the olive oil and almond industries for combined heat power generation in agrifood sector. The experimental consists downdraft fixed bed gasifier, producer gas cleaning cooling system spark-ignition engine–generator set as unit, which generates about 10–12 kW rated electric power. With an average consumption between 13–14 kg/h exhausted pomace pellets feedstock, volumetric flow rate was 31 Nm3/h (vol. %: 19.2 H2, 12.9 CO, 1.9 CH4, CO2, 46.7 N2). cold efficiency nearly 63%. also addresses characterization potential application carbonaceous solid residue (biochar), discharged gasifier at 1.7 kg/h. Finally, economic feasibility developed, wherein payback period ranges 5–9 years.
