We simulated a biorefinery concept with Aspen Plus converting beech wood (400,000 t DM/ae250 MW) to ethylene, organosolv-lignin and fuel.
The overall heat integration of the biorefinery was conducted by pinch analysis.
We economically assessed the biorefinery by a discounted cash flow analysis.
The analysis showed that the biorefinery is not yet profitable under basic assumptions.
We carried out sensitivity analyses to determine the influence of price fluctuations.
