Abstract:

The technical and economic potential of olive mill waste water sludge through catalytic quick pyrolysis is investigated in this study. Using both experimental and published data, a comprehensive data-intensive process and cost model for a 100 wet (93 dry tonnes/day) plant capacity was developed for two schemes (scheme-1: compression refrigeration machine; scheme-2: absorption refrigeration machine). The capital cost for scheme-1 is estimated to be €17.9 M and for scheme-2 €14.1 M. The energy efficiencies of scheme-1 and scheme-2 were estimated to be 52.9% and 53.6% respectively with corresponding minimum fuel selling prices (MFSPs) of €3.02/GGE and €2.49/GGE. The bio-oil minimum fuel sale price is most vulnerable to bio-oil yield, discounted cash flow, and income tax, according to the sensitivity analysis. The findings affirm the economic feasibility of producing bio-oil via catalytic fast pyrolysis.
