Abstract

Models for hydrolysis, fermentation and concentration process, production and utilization of biogas as well as lignin gasification are developed to calculate the heat demand of ethanol production process and the amounts of heat and power generated from residues and wastewater of the process. For the energy analysis, all relevant information about the process streams, physical properties, and mass and energy balances are considered. Energy integration is investigated for establishing a network of facilities for heat and power generation from wastewater and residues treatment aiming at the increase of energy efficiency. Feeding the lignin to an IGCC process, the electric efficiency is increased by 4.4% compared with combustion, which leads to an overall energy efficiency of 53.8%. A detailed sensitivity analysis on energy efficiency is also carried out.

木质纤维素生物质燃料乙醇生产的模拟

开发了水解、发酵和浓缩过程、沼气生产和利用以及木质素气化的模型，以计算乙醇生产过程的热需求以及该过程的废渣和废水产生的热量和电量。对于能量分析，要考虑有关工艺流、物理特性以及质量和能量平衡的所有相关信息。为了提高能源效率，研究了能源整合，建立了一个利用废水和废渣处理进行供热和发电的设施网络。将木质素添加到IGCC过程中，与燃烧相比，电效率提高了4.4%，总体能源效率为53.8%。并对能效进行了详细的敏感性分析。
