Table 2.  Result of 5 biomass plant economic feasibility runs with the MinneBiz™ model.

The yellow fields are for unchanged input parameters

The orange fields are for changed input parameters

The blue fields are for outputs, i.e. model results 

Columns 1 and 2 compare the effect of changes in fuel distribution cost on fuel cost

Columns 2 and 3 show that after making the 150th small plant, product costs are 

      comparable

Columns 3 and 4 show that after making the 2000th small plant, even capital costs of the small plant becomes comparable to that of the large plant, in terms of $/(gal/y)

Columns 4 and 5 show that small plant fuel cost stays competitive even if the biomass cost (w/o transportation cost effects) ate taken at 30 $/ton

Please see more details on the underlying economic model in the BusinessModel page.

Fig. 1. Conceptual sketch of a MinneFuel biomass conversion plant. Rev. 5.

            The plant consist of these basic components:

1. Biomass storage

2. Biomass feeding lock (or screw press)

3. Biomass gasifier

4. Fly ash removing lock 

5. Producer gas cleaning system to make syngas

6. Multi-stage compressor

7. Syngas-to-liquid reactor

8. Liquid refiner and product storage

9. Heat exchangers (not shown for the sake of clarity) and

10. Condensers and water storage (not shown) 

11. Engine generator of electricity

12. Process stream gas composition analyzer (e.g. RLGA by ARI[7])

 

 

 

Fig. 1a.  Sketch of the biomass gasifier system with screw-press feed for the MinneFuel biomass conversion plant (Rev.7).     This indirectly-fired gasifier is self-pressurized and steam-assisted for a small, modular, renewable-fuel plant.  Biomass is input and ash is removed via gas-tight augers. Air and steam pre-heaters contribute to maximizing overall efficiency.
