Gasification of Woody Biomasses and Forestry Residues: Simulation, Performance Analysis, and Environmental Impact

Wood and forestry residues are usually processed as wastes, but they can be recovered to produce electrical thermal energy through processes of thermochemical conversion gasification. This study proposes an equilibrium simulation model developed by ASPEN Plus investigate the performance 28 woody biomass residues’ (WB&FR) gasification in a downdraft gasifier linked with power generation unit. The case assesses Iceland from one ton each feedstock. results for WB&FR alternatives show that net generated input feedstock system is intervals 0 400 kW/ton, more 50% systems located range 100 200 that, among them, derived tamarack bark significantly outranks all other producing 363 kW/ton. Moreover, environmental impact these assessed based on categories global warming (GWP), acidification (AP), eutrophication (EP) potentials normalizes impact. electricity environmentally friendly 75% studied (confirmed normalized [NEI] less than 10) fed birch bark, NEI lower 5, outrank owing favorable obtained sector.
