Abstract
The economic evaluation of a biomass to ethanol process using a fluidized bed gasifier was conducted by using domestic biowastes. In this work, we chose two different scale processes because collecting biowastes was considered as one of biggest bottlenecks. Economic evaluation was conducted using internal rate of return, net present value and ethanol prices. NPVs from a 2000 dry-ton/day process and two 1000 dry-ton/day process ranged from 47.9 million dollars and 69.5 million dollars in same IRR of 10%. The construction of a 2000 dry-ton/day scale plant might be more economical than two 1000 dry-ton/day scale plants because of lower ethanol prices.
