Feasibility Study on Bioethanol Production by One Phase Transition Separation Based on Advanced Solid-State Fermentation

To fulfill the consumption demand of low-cost fuel ethanol, an advanced process for feedstock fermentation and bioethanol extraction was required. This study proposed a combined continuous solid-state distillation vapor permeation to extract ethanol from fermented sweet sorghum bagasse on basis technology. Ethanol undergoes only one phase transition separation in whole process, which drastically reduces energy compared repeating transitions that occur conventional production. The mass balance combining processes were simulated overall. A techno-economic evaluation conducted flowsheet. Costs profit produced by bioethanol-producing technology comprehensively calculated. results present show is efficient cost-effective alternative
