Novel Hybrid Reactive Distillation with Extraction and Distillation Processes for Furfural Production from an Actual Xylose Solution
نویسندگان
چکیده
Furfural is only derived from lignocellulosic biomass and an important chemical used in the plastics, agrochemical, pharmaceutical industries. The existing industrial furfural production process, involving reaction purification steps, suffers a low yield intensive energy use. Hence, major improvements are needed to sustainably upgrade process. In this study, conventional process based on continuous stirred tank reactor distillation columns was designed optimized actual aqueous xylose solution via pretreatment step. Subsequently, reactive (RD) extraction/distillation (ED) configuration proposed for respectively, improve efficiency. RD can remove instantly liquid phase separate heavy components raw stream, while ED with toluene butyl chloride as extracting solvents effectively dilute stream. results showed that hybrid RD-ED using solvent saves up 51.8% 57.4% of total investment costs annual costs, compared Furthermore, environmental impacts were evaluated all structural alternatives.

Techno-economic assessment of hybrid extraction and distillation processes for furfural production from lignocellulosic biomass
BACKGROUND Lignocellulosic biomass is one of the most promising alternatives for replacing mineral resources to overcome global warming, which has become the most important environmental issue in recent years. Furfural was listed by the National Renewable Energy Laboratory as one of the top 30 potential chemicals arising from biomass. However, the current production of furfural is energy intens...
متن کاملHybrid membrane-distillation processes
This work focuses on modelling, simulation and process analysis of hybrid membrane separations namely on distillation and pervaporation. Such hybrid process can be applied for the separation of multicomponent azeotropic mixtures without the use of entrainer. Its application is illustrated by the separation of a non-ideal ternary mixture of acetone, isopropanol and water. The extended abstract d...
متن کاملReactive distillation for methyl acetate production
We describe a hierarchy of methods, models, and calculation techniques that support the design of reactive distillation columns. The models require increasingly sophisticated data needs as the hierarchy is implemented. The approach is illustrated for the production of methyl acetate because of its commercial importance, and because of the availability of adequate published data for comparison. ...
متن کاملDesigning reactive distillation processes: present and future
The potential benefits of applying reactive distillation (RD) processes are taxed by significant complexities in process development and design. The design problem is formulated in the wider context of process development and engineering. From that perspective design methods for RD units developed over the last decades are classified and described. A fingerprint of the most representative work ...
متن کاملOptimization of reactive distillation processes with simulated annealing
A simulated annealing-based algorithm (MSIMPSA) suitable for the optimization of mixed integer non-linear programming (MINLP) problems was applied to the synthesis of a non-equilibrium reactive distillation column. A simulation model based on an extension of conventional distillation is proposed for the simulation step of the optimization problem. In the case of ideal vapor}liquid equilibrium, ...
