Chemical Engineering 3B (U00455)

? Credit Points : 40 ? SCQF Level : 9 ? Acronym : EEL-3-CHCEB

This course covers the following topics: Heat, Mass and Momentum Transfer; Thermodynamics; Environmental issues. The fundamentals of heat, mass and momentum transfer are presented, including analogies between the transfer mechanisms for convective transfer and treatment of radiative heat tranfer. Thermodynamics covers thermodynamic cycles of particular significance to chemical engineers, the concepts of Gibbs Free Energy and chemical potential and their relationship to both phase equilibrium and chemical reaction equilibrium in ideal systems and the calculation of heats of reaction and equilibrium concentrations for gas phase reactions using standard thermodynamic data. In Environmental Issues students cover contemporary environmental concerns as they impinge on the practising engineer, the legal and regulatory background to engineering activity and the procedures to be followed in seeking a license from the environmental protection agencies for the operation of processes involving prescribed substances. Generation, propagation and the fate of pollutants discharged to the air, to water and to the ground are discussed along with means of mitigating emissions by elimination, substitution and pre-discharge treatment.

Summary of Intended Learning Outcomes

Students should be able to:
- identify and describe heat, mass and momentum transport mechanisms
- develop and solve models for physical transport problems
- solve problems in turbulent transport using empirical approaches and the Chilton-Colburn analogy
- describe phase change and its effect on transport problems
- quantify the role played by radiation heat transfer in physical problems
- perform a heat exchanger design using Kern's method
- use non-Newtonian models to obtain velocity profiles for shear-thinning, shear thickening and Bingham fluids
- assess validity of modelling approaches taken by e.g. checking assumptions and magnitude of dimensionless parameters
- represent power generation and refrigeration cycles on T-S and P-H diagrams and determine the power generation or requirement for a given thermal duty
- apply the phase rule to determine degrees of freedom and show how these may be satisfied
- describe the significance of Chemical Potential in mixtures
- use Standard heats and free energies of formation to evaluate equilibrium constants, and hence determine equilibrium
- concentrations in reacting mixtures at elevated temperatures and pressures
- describe the national and international environmental legislative framework
- deduce from environmental standards the required operating performance of chemical plant
- select plant and processes in the light of targets limiting the emissions of acid and greenhouse gases
- calculate dispersal of gaseous emissions in vents and plumes
- Interpret terms used in the regulation of aqueous emissions, translating these into limits on discharge rates. Calculate the effect of BOD discharge into waterways and select waste disposal treatments
- Appreciate the hazards of landfill disposal and the requirements for safe landfill management
- Select waste minimisation and recycling strategies as alternatives to, or mitigation of, discharge, dumping and incineration of waste.
