Model-Based Dosing Control of a Pellet Softening Reactor
The control of a drinking-water treatment plant aims to produce the correct quantity of water, with a constant quality. Achieving constant water quality is not an obvious task, since the online water-quality measurements and possible control actions are limited. Applying model-based control improves disturbance rejection and online process optimisation. For the softening process step, the integ...
متن کاملDEVELOPMENT OF A PELLET SCALE MODEL FOR TRICKLE BED REACTOR USING CFD TECHNIQUES
In this study, a pellet scale model was developed for trickle bed reactor utilizing CFD techniques. Drag coefficients were calculated numerically at different velocities and bulk porosities in the case of single phase flow through the dry bed. The simulation results were then compared with the prediction of Kozeny-Carman (K-C) equation. The results indicated that drag coefficients calculated fr...
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 کاملControl of a Fluidized Bed Polyethylene Reactor
In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...
متن کاملpH control of a fed batch reactor with precipitation
In this paper, the problem of controlling the pH, in a fed batch reactor where precipitation occurs, is considered. Due to the batch nature of the production and the effects of precipitation, the control problem is rather different from the well studied cases of continuous processes, which are usually considered under the assumption of perfect solubility. To fulfill this objective on a presente...
