“…There are many methods for transesterification reactions, such as conventional stirred tank reactors, bio-processing processes [4], membrane reactors [5], microreactors [6], reactive distillation [7], etc. The reactive distillation process has drawn increased attention in recent years from industrial and academic research due to its significant potential for process intensification, especially in equilibrium reactions, as it can shift equilibrium and lead to higher conversions and selectivity.…”

Glycerol carbonate is one of the valuable products that can be converted from glycerol produced in the biodiesel industry. In this work, the continuous process of glycerol carbonate production via transesterification from crude glycerol and diethyl carbonate will be developed using Aspen Plus simulation. There are two processes to be considered. First, the separated reaction/distillation (SRD) process consists of a continuously stirred tank reactor for the reaction section and a distillation column for the purification section. Second, the reactive distillation (RD) process consists of a reactive distillation column that can accommodate both the reaction and purification in a single column, and a conventional distillation column for the purification section. After the design is complete, the optimization will be done by connecting the model in Aspen Plus to MATLAB and using the Genetic Algorithm to optimize the model. The results show that the RD process is superior to the SRD process in terms of both performance and economics. The RD process can shift the reaction equilibrium, resulting in high conversion and a large quantity of product. Moreover, when considering the economic value, the RD process is also better due to its lower total capital cost, lower operational cost, lower total annual cost, shorter payback period, and higher %IRR.

Microstructured reactors offer fast chemical engineering transfer and precise microfluidic control, enabling the determination of reactions’ kinetic parameters. This review examines recent advancements in measuring microreaction kinetics. It explores kinetic modeling, reaction mechanisms, and intrinsic kinetic equations pertaining to two types of microreaction: esterification and transesterification reactions involving acids, bases, or biocatalysts. The utilization of a micro packed-bed reactor successfully achieves a harmonious combination of the micro-dispersion state and the reaction kinetic characteristics. Additionally, this review presents micro-process simulation software and explores the advanced integration of microreactors with spectroscopic analyses for reaction monitoring and data acquisition. Furthermore, it elaborates on the control principles of the micro platform. The superiority of online measurement, automation, and the digitalization of the microreaction process for kinetic measurements is highlighted, showcasing the vast prospects of artificial intelligence applications.
