Reactor Design Applications in Industry

The reactor, the apparatus in which the reactions take place, provides the required volume or the required amount of catalyst for the reaction. Reactors should also be equipped to ensure proper temperature and concentration distribution. For this reason, the selection and design of the reactor should be made considering the ideal conditions and the economic, safe and environmentally friendly operation of the plant.
reactor design; It is obtained from simultaneous solutions of equations (mostly differential equations) obtained by considering mass and energy balances, chemical kinetic (reaction rate expression, etc.) information together.
Many accidents in industry result from poor design and operation of the chemical reactor. Therefore, a reactor should be designed under realistic conditions. In the design, not only the reactor dimensions and the design results such as the number of pipes should be considered, but also the transfer of heat energies to be taken / given in the reactor, the selection and design of the mixer in liquid reactors, the mechanical design of the reactor, safety measures and process control systems should also be designed. Since reactor safety and controllability problems will arise especially in exothermic and irreversible reactions, both the control systems and the discharge systems of the reactor should be designed very well in this type of reactors.
In the book; Basic information about mechanical design, control and safety systems in reactors is presented and industrially used batch reactor, continuously fed stirred tank reactor, piston flow fixed bed and multi-tube reactor, fluidized bed reactor, bubbling liquid-gas phase reactor and furnace reactor where thermal molecule fragmentation is performed. By giving the design principles of different types of industrial reactors, examples of their applications in this industry are given.
The examples listed below are selected from the semester projects prepared by my graduate students who took the Analysis of Chemical Reactor course that I taught at the Department of Chemical Engineering at Ege University.
• Batch Tank Reactor Design in Bioethanol Production
• Continuously Feeding Stirred Reactor in Biodiesel Production
• Cumene Production in Fixed Bed and Piston (Plug) Flow Reactor (PAR)
• Methanol Production from Carbon Dioxide in a Multi-Tube Reactor
• Production of Acrylonitrile from Propylene with a Fluidized Bed Reactor
• Ethylene Production by Thermal Cracking of Ethane
• Production of Ethylbenzenehydroperoxide from Ethylbenzene
• Reactor Design in Biological Wastewater Treatment
• Reactor Design in Wet Air Oxidation
In conclusion, this book has been prepared as a useful resource for undergraduate and graduate students and engineers interested in industrial reactor design.
