3 Biorefinery Activities Processes for the conversion of biomass to SNG, methanol, mixed alcohols and FT-liquids are developed and analyzed by flowsheet simulations. Biomasse ca. 9 t/h (55% TS) 30 MW RME 0,7 MW Gasreinigung Rohgaskühler Kompressor Strom- Eigenbedarf 1 MW Trockner Systemgrenze Vergasung Dampf Luft FICFB-Vergaser Filter Öl-Wäscher Sauergas- Wäscher ZnO-Filter Methanisierung Wasserstoff Kompressor Methanisierung Gasaufbereitung H2-Membran CO2-Wäscher Glykol- Trocknung SNG ca. 19,5 MW Wärme ca. 2,5 MW Mass and energy balances are calculated to estimate efficiencies. Heat integration is applied by pinch analysis. The economic viability is analyzed e.g. investment, production costs, sensitivity analysis Sonstiges 26% Commissioning 2% Engineering 9% Gasaufbereitung 10% Methanisierung 9% Biomassevorbehandlung 7% Vergasung 18% Gasreinigung 19% BioSNG Gestehungskosten in ct/kwh SNG Sensitivität BioSNG Altholz 30 MW 6-60% -40% -20% 0% 20% 40% 60% 80% Parametervariation Investionsvolumen (57 Mio. ) Kalkulationszinsfuß (8 %) Biomassekosten (0 /t) Jahresbetriebsstunden (7500 h/a) Strompreis (10 ct/kwh) Nutzungsdauer (20 a) Wärmeverkaufspreis (3 ct/kwh)
