| Abstract |
Featured Application Agrifood industries may benefit from investing in energy efficiency and diversifying into new business models (distributed cogeneration and biochar production) through waste gasification, while promoting circular economy and environmental sustainability. This research work presents a techno-economic analysis of a biomass gasification plant fueled with residues from the olive oil and almond industries for combined heat and power generation in the agrifood sector. The experimental plant consists of a downdraft fixed bed gasifier, a producer gas cleaning and cooling system and a spark-ignition engine-generator set as a power generation unit, which generates about 10-12 kW of rated electric power. With an average consumption between 13-14 kg/h of exhausted olive pomace pellets as feedstock, the producer gas volumetric flow rate was 31 Nm(3)/h (vol. %: 19.2 H-2, 12.9 CO, 1.9 CH4, 19.2 CO2, 46.7 N-2). The average cold gas efficiency was nearly 63%. This work also addresses the characterization and potential application of the carbonaceous solid residue (biochar), discharged from the gasifier at 1.7 kg/h. Finally, an economic feasibility analysis was developed, wherein the payback period ranges between 5-9 years. |
