CAPE5315M Chemical Engineering Principles**This module is not approved as an Elective**

### Module summary

- Fundamentals of chemical engineering, including chemical process calculations, chemical thermodynamics, momentum and heat transfer;- Use of HYSYS software for process calculations and modelling.### Objectives

On completion of this module, students should be able to:- Develop a holistic understanding of the basic principles of chemical engineering;

- Develop a deep understanding of the concepts and methodology for performing mass and energy balance calculations for processes with chemical reactions, combustion and recycles;

- Develop a deep understanding of the fundamentals of chemical thermodynamics;

- Develop a deep understanding of fundamental principles of fluid mechanics and heat transfer;

- Apply HYSYS software for process calculations and modelling;

- Develop a basis for the design project module.

**Learning outcomes**

On completion of this module, students with a non-chemical engineering degree should develop a coherent understanding of the basic principles of chemical engineering and the ability to apply them to solve relevant problems, including:

1. Process calculations (mass and energy balances);

2. Physics associated with chemical thermodynamics;

3. Fluid mechanics;

4. Heat transfer;

5. Use of HYSYS software for process calculations and modelling.

This will provide them with a solid foundation for studying the MSc Chemical Process Engineering course, including carrying out an extensive process and plant design project.

**Skills outcomes**

- Ability to set up and solve mass and energy balances for industrial processes with chemical reactions, combustion and recycles;

- Ability to understand underlying physics associated with chemical thermodynamics and apply knowledge to complex processes;

- Ability to design pipelines and heat exchangers;

- Ability to use HYSYS for process calculations and modelling.

### Syllabus

1. Chemical process calculations:

1.1 Mass Balance - Reactive systems; principles of stoichiometry, limiting and excess reactants, conversion, selectivity and process yield. Mass balances for reactive systems; mass balances on molecular and atomic species, independent equations, independent species, independent reactions, extent of reaction, mass balances for combustion processes, including calculation of the product composition from the combustion of hydrocarbon fuels. Mass balances for systems with recycle, bypass and purge streams. Mass balances for transient processes.

1.2 Energy Balance - Energy balances for reacting systems; reference states, heats of reaction, formation and combustion, energy balances on isothermal and adiabatic chemical reactors. Calculation of flame temperatures. Energy balances for combustion equipment. Energy balances for transient processes. Simultaneous mass and energy balances.

2. Chemical thermodynamics: The first, second and third laws of thermodynamics, P-v-T relationships for fluids, equations of state, vapour-liquid equilibrium, chemical equilibrium. Gibbs free energy, chemical potential.

3. Momentum and heat transfer:

3.1 Fluid Mechanics - Classification of fluid flows and basic flow characteristics, continuity, energy and momentum equations. Laminar flow; flow in pipes and Hagen-Poiseuille equation, flow through ducts, flow between parallel plates and over inclined/vertical plate. Turbulent flow; fluctuating and mean velocity, Reynolds stresses and eddy-viscosity, power-law velocity profiles, log-law of the wall. Boundary layer flow over a flat solid surface, boundary layer thickness, velocity distribution and shear stress. Compressible flows in pipes.

3.2 Heat Transfer - Mechanisms of heat transfer. Natural and forced convection, thermal boundary layer, log mean temperature difference (LMTD), individual and overall heat transfer coefficients, correlations for laminar/turbulent flows in pipes. Heat exchanger design - types of heat exchangers, mechanical construction, shell-and-tube heat exchanger design using LMTD and effectiveness-NTU methods.

4. Process modelling: Use of HYSYS for simulation of process mass and energy balances and unit operations.
