Special Issue Information

Dear Colleagues,

The sustainable conversion processes for producing biofuels and biochemicals from biomass in biorefineries have attracted increased attention in recent years. However, the main issue associated with biomass products is their low concentration in the final product line, resulting in the energy- and cost-intensive recovery of high added-value products. This has prompted process industries to search for all possible advanced and intensified configurations to significantly reduce the product recovery cost in order to make the process viable and competitive. This Special Issue will publish studies demonstrating various methods, developments, and theories in the field of process engineering to facilitate biomass derivative separation and purification using advanced and intensified distillation processes. Scientific investigations and industrial practices on process design, integration, and intensification in order to substantially improve efficiency and performance and reduce cost will be the main body of the Special Issue. Relevant sub-topics from both research (experimental, numerical, and simulated) and applications are also welcomed.

The scope of this Special Issue covers, but is not limited to, the following topics:

  • Hybrid and advanced distillation technologies for the separation and purification of biomass derivatives;
  • Reactive distillation processes;
  • Techno-economic analysis and sustainability analysis;
  • Process design, integration, and intensification;
  • Process modeling, simulation, and optimization;
  • Biorefinery development and case studies;
  • Sustainable approaches for biofuel and biochemical production technologies;
  • Integrated lignocellulosic biorefinery for a sustainable bio-based economy;
  • Energy efficiency.

Advanced processes, which are alternatives to ordinary distillation, are essential to dehydrate azeotropic alcoholic mixtures for biofuel production. In that regard, this work focuses on the analysis of heterogeneous azeotropic distillation for the separation of a 2-propanol + water mixture in order to recover the alcohol with a sufficiently low water content. By comparing the performances of various entrainers on the basis of ternary maps, isooctane was selected for further process analysis. An advantage it poses is related to the fact that traces of it within the recovered dehydrated alcohol are highly welcome with a view to its subsequent use as a fuel. Aspen Plus® V11 software was employed for the simulation of the process, thus filling the gap existing in the literature due to the lack of studies on the process analysis of the heterogeneous azeotropic distillation of the 2-propanol + water system using isooctane as an entrainer.

Cellulosic ethanol (CE) can not only be produced from a nonedible, cheap, and abundant lignocellulose feedstock but also can reduce carbon footprint significantly compared to starch ethanol. Despite great stimulation worldwide, CE production has not yet commercialized because of the complexity of lignocellulose. Therefore, intensive research and development are needed to improve CE technologies. In this study, a cost-efficient and sustainable design was proposed for the coproduction of CE, heat, and electricity from the actual lignocellulosic fermentation broth. First, a conventional coproduction process of CE, heat, and electricity based on hybrid distillation and adsorption (HDA) was simulated and optimized. Subsequently, various heat integrated (HI) techniques such as heat pump (HP), multi-effect distillation (MED), and combined HP-MED were evaluated to improve the CE process. The combined heat and power (CHP) process that utilized the combustible solids of the beer stillage was designed and integrated with the CE process. Structural alternatives were assessed for both economic and environmental impacts. The results show that the proposed HI-HDA process can save 36.9% and 33.6% of total annual costs and carbon footprint, respectively, compared to the conventional CE process. In the proposed HI-HDA coproduction process, the CE recovery process can be self-efficient in energy and the CHP can generate 12.0% more electricity than that in the conventional coproduction process.
