Course Description

The course is an introduction to the chemical reactor design and is constricted to the isothermal, constant density systems. You'll learn the know-how of design of ideal batch reactor, plug flow reactor and the continuous stirred tank reactor.

Build a strong foundation which will help you tackle additional advanced topics in the chemical reactor design!

In this course you will be able to:

  • distinguish between batch and continuous operating mode
  • derive the mole balances which are the basis of the reactor design.
  • derive design equations
  • provide analytical solutions for the first and second order reactions
  • relate the parameters such as volume, conversion and reaction time to each other.
  • size flow reactors graphically using the Levenspiel Plot
  • compare flow reactors graphically and discuss the meaning of their differences.

The course deals with ideal reactors which are strongly simplified models of real chemical reactors. It conveniently summarizes the introduction to the chemical reactor design with its user friendly, colorful and concise approach.

I designed this course mainly for students at undergraduate levels of chemical engineering. There are many equations necessary to be understood in this course. Write them down many times and you are well on your way to design and specify chemical reactors confidently.

What are the requirements?

  • basic knowledge of chemical kinetics & calculus (integration, derivation)

What am I going to get from this course?

  • derive mole balance
  • derive design equations
  • derive analytical solutions
  • size reactors graphically using Levenspiel Plot

What is the target audience?

  • all engineers
  • students of chemical reaction engineering

Curriculum

Section 1: Introduction
02:47

Students will learn what the course is about and how to take it

Section 2: Basic Elements of the Chemical Reactor Design
02:33

Students will learn how to approach the reactor design and what conditions we restrict ourselves to in this course

04:57

This lecture is a revision of the basics of kinetics. Students will learn how the kinetic laws are applied to the reactor design

02:52

This lecture derives the general mole balance which is the basis of the reactor design. Students will learn how to perform the general mole balance of a component

05:10

The lecture gives an overview over the three ideal reactors: batch reactor, plug flow reactor and a continuous stirred tank reactor. Students will get to know the operating mode of each of the reactors.

03:16

The lecture describes time quantities used in the chemical reactor design. Students will learn to distinguish between different time quantities and how they are applied to different reactors.

03:16

The lecture describes the conversion as the measurement of the extent of the reaction. Students will learn how to express concentrations and molar flows in terms of conversion.

03:49

Students will learn what each section is about and how they relate to each other

Section 3: Introduction to the Ideal Reactors
04:22

We will introduce three ideal chemical reactors, describe their operating mode and assumptions to be made in modelling of the ideal reactors

Section 4: Mole Balance for Ideal Reactors
04:16

A mole balance for the component A will be derived for each of the reactors. Students will learn how different operating modes affect the derivation of mole balance.

Section 5: Design Equations
02:50

Students will learn to derive differential and integral design equations for batch reactor.

02:36

Students will be learn how to derive analytical solutions for the 1st and 2nd order reactions for cstr

Section 7: Sizing of Flow Reactors with Levenspiel Plot
03:41

In this lecture we will size the pfr graphically using Levenspiel Plot. Students will learn how to find the volume and space time necessary for a given conversion

03:35

In this lecture we will size the cstr graphically using Levenspiel Plot. Students will learn how to find the volume and space time necessary for a given conversion

03:11

In this lecture we will compare pfr and cstr using Levenspiel Plot. Students will understand why different reactor sizes are necessary for the same conversion
