Optimization of Biodiesel Synthesis in a Batch reactor using Maximum Principle
Abstract: Biodiesel is produced through transesterification of vegetable oils or animal fats. It significantly depends on many reaction parameters among which temperature and stirring are most important. In transesterification, reaction rates follow Arrhenius equation (i.e. function of temperature). Also, effect of stirring effect on reaction rate can be described as Boltzmann sigmoid form (as ...
متن کاملOptimal control of biodiesel production in a batch reactor: Part II: Stochastic control
The determination of time-varying profiles through dynamic optimization is an exclusive characteristic of optimal control problems; however, these types of problems become more challenging when variability and uncertainty in any parameter is included. In biodiesel production, there are inherent uncertainties arising due to variation in initial composition, operating parameters, and mechanical e...
متن کاملBiodiesel Production in Batch Tank Reactor Equipped to Helical Ribbon-like Agitator
Biodiesel as an alternative and renewable fuel could be applied in diesel engines in order to reduce air contamination and dependence to fossil fuels. So far, various processes were prepared for biodiesel production, but using transesterification method via base catalyst in batch reactors could result in a reasonable yield of biodiesel. At the present study, a batch tank reactor equipped to a h...
متن کاملA Control System for A Pilot Batch Polymerization Reactor
In this article several control schemes for a pilot scale polymerization reactor are proposed and one of them is selected as the most suitable design. The performances of proposed schemes have been compared through computer simulations. The controllers are PID and Chosen reaction is polymerization of methyl methacrylate which is highly exothermic.
متن کاملA Continuous-flow Reactive Distillation Reactor for Biodiesel Preparation from Seed Oils
In biodiesel preparation from vegetable oils and alcohol through transesterification process in the presence of a catalyst, excess alcohol, typically 100% more than the theoretical molar requirement, is used in existing batch and continuous-flow processes in order to drive the reversible transesterification reaction to a high enough conversion rate. The excess alcohol needs to be recovered in a...
