Design and optimization of intensified biorefinery process for furfural production through a systematic procedure

摘要: Abstract Furfural, which is used as a precursor for the production of many other industrial chemicals, has been identified one major bio-based platform chemicals that can compete with petroleum-based chemicals. On hand, current commercial furfural process low yield and energy-intensive. Therefore, this study develops biorefinery from lignocellulosic biomass using heat integration intensification. In particular, distillation unit requires considerable energy, highlighting need to improve energy efficiency, motivation work. An integrated intensified sequence, including an innovative bottom dividing wall column decanter configuration (BDWC-D) was suggested enhance cost efficiency through comprehensive systematic procedure combines intensification integration. The structures complex columns in all sequences were optimized optimization method-response surface methodology (RSM). All simulations conducted Aspen HYSYS. results show proposed sequence reduce total annual carbon footprint by 10.1% 11.6%, respectively compared conventional sequence.
