Kemiallinen reaktiotekniikka (Y0026), 3 op

Basic information

Prerequisites

Course contents (core content level)

The classification of chemical reactions on the basis of their exothermic and endothermic nature, their homo- and heterogeneity and on the basis of the number of reaction steps; deepening the concept of reaction equilibrium in terms of activity, concentration and partial pressure, conversion; reaction kinetics: the determination of reaction rate constant and reaction order on the basis of experimental data, the dependence of reaction rates on temperature; classification of chemical reactors, determination of reactor volumes on the basis of space time for 0th, 1st and 2nd order reactions, reaction groups, selectivity of reactions.

Course contents (additional)

Core content level learning outcomes (knowledge and understanding)

After completion of this course the student understands the meaning of reaction equilibrium and reaction rate when assessing the volume of a chemical reactor. He knows the operating principles and fields of application for the most common reactor types, as well as their advantages and disadvantages. He also understands the benefits of connecting reactors in series and in parallel in different types of processes. In addition, the student knows how to influence the yield and selectivity of chemical reactions.

Core content level learning outcomes (skills)

After completion of this course the student is able to assess the equilibrium composition of a chemical reaction using as a starting point the equilibrium constant in terms of activity, concentration and partial pressure. He also knows how to determine the equilibrium conversion of a reaction using thermodynamic handbook data. In addition, the student is able to determine the reaction rate constant and the order of reaction, i.e. the rate law, for a chemical reaction using experimental data. He can also calculate the volume of a batch reactor, a mixed reactor and a plug reactor in the case of a 0th, 1st and 3rd order reaction, as well as apply tools developed in the field of numerical mathematics in the calculations.
