Online Dynamic Optimization of Feed Flowrate and Temperature Trajectories in Semi Batch Esterification Reactor

In semi batch esterification process, an operating feed flowrate and temperature reactor has a significant effect on conversion that determines final product quality

Dynamic Optimization of Autocatalytic Esterification in Semi Batch Reactor using Orthogonal Collocation and Control Vector Parameterization Method

Catalyzed Esterification of Propionic Anhydride with 2-Butanol is commonly applied in semi batch reactors where the process variables undergo significant changes during the duration of the batch. In this semi batch operation, there is no steady state and thus no constant setpoints around which the key variables can be regulated

Simulation And Optimization Studies Of Catalyzed Esterification Of Propionic Anhydride With 2-Butanol: Batch Versus Semi Batch Operation.

A model to represent the catalyzed esterification of propionic anhydride with 2-butanol has been developed and simulated

Mathematical Model of Ion Transport in Electrodialysis Process

<p>Mathematical models of ion transport in electrodialysis process is reviewed and their basics concept is discussed. Three scales of ion transport reviewed are: 1) ion transport in the membrane, where two approaches are used, the irreversible thermodynamics and modeling of the membrane material; 2) ion transport in a three-layer system composed of a membrane with two adjoining diffusion layers; and 3) coupling with hydraulic flow system in an electrodialysis 2D and 3D cell, where the differential equation of convectivediffusion is used. Most of the work carried out in the past implemented NP equations since relatively easily coupled with other equations describing hydrodynamic conditions and ion transport in the surrounding solutions, chemical reactions in the solutions and the membrane, boundary and other conditions. However, it is limited to point ionic transport in homogenous and uniformly - grainy phases of structure. © 2008 BCREC UNDIP.
