Economic evaluation of biofuel production through bio-gasification power facility using modeling method.

摘要

Since bio-gasification is a potentially more efficient way to utilize bio-energy, the economic feasibility becomes one of the greatest issues when we apply this new technology. Evaluation of economic feasibility of a bio-gasification facility needs understanding of its production unit cost under different capacities and different working shift modes. The objectives of this study were to evaluate the unit cost of bio-syngas and bio-fuel products at different capacities by using economic modeling method. Result showed that economic feasibility of a power facility was significantly affected by its production capacity and operating mode (one shift, two shifts, or three shifts mode). Economic feasibility could be improved by increasing production capacity or by changing operating mode to two or three shifts from one shift. The economic evaluation model and cost analysis software developed in this study could be a good tool for economic analysis of bio-syngas and bio-fuel products from biomass gasification.
