This module is not approved as an Elective
Objectives
On completion of this module, students should be able:- to provide a holistic understanding of the basic principles of chemical engineering including: thermodynamics, momentum, heat and mass transfer, and process control.
- to provide experience in working with laboratory-scale process equipment.
- to provide a basis for the plant design project in CAPE5310M Chemical Process Technology and Design module.
Learning outcomes
On completion of this module, students with a non-chemical engineering degree should develop a coherent understanding of the above mentioned basic principles of chemical engineering, which will provide them with a solid foundation for studying the MSc Chemical Engineering course. The students will also gain experience in operation of laboratory-scale process equipment.
Syllabus
- Engineering/chemical thermodynamics
Engineering thermodynamics: The first, second and third laws of thermodynamics, reversible and irreversible processes, entropy and enthalpy, Rankine cycle, Carnot cycles, heat engines and thermal efficiency. Chemical thermodynamics: P-v-T relationships for fluids, equations of state, vapour-liquid equilibrium, chemical equilibrium. Gibbs free energy, chemical potential.
- Fluid Mechanics
Mechanisms of momentum transfer and Newton's law of viscosity. Classification of fluid flows, basic flow characteristics and concept of hydrodynamic boundary layer. Pressure distributions in static fluid. Basic equations of fluid motion: continuity, energy and momentum equations. Laminar Flow: flow in pipes and ducts and Hagen-Poiseuille equation. Turbulent Flow: fluctuating and mean velocity, Reynolds stresses and eddy viscosity, power-law velocity profiles, friction factor, pressure drop. Flow and pressure drop in pipeline systems including frictional losses due to sudden expansion/contraction and entrance/exit of pipes and fittings.
- Heat Transfer
Mechanisms of heat transfer: conduction, convection and radiation. Conduction: Fourier's law, steady-state conduction through a flat and cylindrical wall, composite walls and thermal resistance in series. Convection: natural and forced convection, thermal boundary layer, log mean temperature difference (LMTD), individual and overall heat transfer coefficients, correlations for laminar and turbulent flows in pipes. Radiation: radiation intensity, blackbody radiation, surface absorption, reflection and transmission. Heat exchanger design: classification of heat exchangers, mechanical construction, shell-and-tube heat exchanger design using LMTD and effectiveness-NTU methods.
- Mass Transfer
Mechanisms of mass transfer: molecular diffusion and convection. Molecular diffusion in gases and liquid, Fick's law of diffusion and diffusion coefficients. Convective mass transfer coefficients and correlations.
- Process Control
Introduction to automatic control, block diagram and transfer function, feedback control systems, feedback controller tuning.
- Operations of Laboratory-Scale Process Equipment
Students will work in groups and carry out a series of experiments designed to provide experience in operating laboratory-scale process equipment and to demonstrate various concepts of fluid flow, heat and mass transfer processes and process control.
