The chemical reactor is the `heart¿ of the chemical process and this module aims to demonstrate how the performance of the reactor is key to successful chemical process design and optimisation. The principles of chemical equilibrium, reaction kinetics, mass balances and thermodynamics are applied to the design of the basic types of chemical reactors (batch reactors, tubular flow reactors, and continuous stirred tank reactors) in order to show how the design of the reactor influences the productivity, selectivity and economics of the chemical process, leading to the development of safe and sustainable production facilities. Practical physical design of tanks and tubular reactors are also considered, along with typical industrial configurations and relevant safety systems.
This module continues to develop further the concepts studied in the Level 2 Reactor Design Course (EG-204). The engineering design of reaction vessels will be considered for chemical and biological reaction systems that involve simultaneous reaction with mass transfer limitations in the fluid phase and the solid phase matrix that contain either a physio-chemical, or biological catalyst. Mathematical modelling of the kinetic rate equations therefore incorporates the concept of a mass transfer limitation effectiveness factor for the solid phase matrix, whilst the fluid mechanics is used to determine the fluid phase transfer limitations. The kinetic rate models are used to develop Design Performance Equations for industrial reaction systems.
