Techno-Economic Analysis of Biofuels Production Based on Gasification

摘要: This study compares capital and production costs of two biomass-to-liquid plants based on gasification. The first biorefinery scenario is an oxygen-fed, low-temperature (870?C), non-slagging, fluidized bed gasifier. second high-temperature (1,300?C), slagging, entrained flow Both are followed by catalytic Fischer-Tropsch synthesis hydroprocessing to naphtha-range (gasoline blend stock) distillate-range (diesel liquid fractions. Process modeling software (Aspen Plus) utilized organize the mass energy streams cost estimation used generate equipment costs. Economic analysis performed estimate investment operating Results show that total required for nth plant scenarios $610 million $500 scenarios, respectively. Product value (PV) estimated be $4.30 $4.80 per gallon gasoline equivalent (GGE), respectively, a feedstock $75 dry short ton. Sensitivity also process economic parameters. shows among most influential parameters affecting PV.
