| Description:
| Aims: To introduce the principles and practices of: * material and energy balancing, both steady state and unsteady state, for non-reacting and reacting systems in chemical and biochemical engineering, * reaction engineering as applied to chemical and biological reactor design, and * separation processes of relevance to the chemical engineering profession, including how these subjects are integrated in process design and analysis. Learning Outcomes: After successfully completing this unit students should be able to: * Formulate and solve manually material and energy balances for process systems that may include multi-component streams, phase changes, simple reactions, recycles, purges, by-passes and mixing; * Perform simultaneous material and energy balances on adiabatic, non-adiabatic and isothermal reactors, including equilibrium-controlled reactions; * Calculate reaction orders, rate constants and half-lives for simple reaction mechanisms; * Apply the Arrhenius equation to calculate activation energies; * Distinguish between various reactor types and explain their applications in chemical and biochemical processes; * Outline the basic features of membrane processes, distillation processes, absorption processes and liquid /liquid extraction processes; * Select appropriate membrane technologies for a particular separation problem; * Understand the operation of single and multistage distillation columns; * Design simple multistage binary distillation columns; and * Carry out ternary multistage solvent extraction calculations. Skills: Analysis and problem solving (taught/facilitated and assessed). Content: * Law of conservation of mass. * Material balances on non-reacting systems, steady and unsteady state (continuous, batch, semi-batch, and batch-fed). * Synthesis of the process flowsheet; the process flow diagram. * Material balances on reacting systems (stoichiometry, elemental balances, conversion, yield, recycle, purge, by-pass and mixing). * Forms of energy and their inter-changeability. * Sensible and latent heats; mixing and solution; multicomponent systems. * First and second laws of thermodynamics; the general energy equation for closed and open (flow) systems. * Heats of formation, reaction and combustion; standard and non-standard conditions. * Energy balances on single and multiphase systems with and without reaction (adiabatic, non-adiabatic and isothermal systems). * Incomplete conversion, excess reactants, inerts. * Material and energy balances in combustion. * Elementary and non-elementary reactions. * Order of reaction and analysis of rate data. * Homogeneous and heterogeneous reactions. * Kinetic rate expressions; rate and equilibrium constants; Arrhenius equation and activation energy; conversion and yield. * Reactor types and basic design equations. * Overview of available separation processes. * Fundamental principles of phase equilibrium relationships. * Principles of vapour/liquid equilibrium. * Principles of single stage equilibrium flash. * Principles of multistage contacting and counter-current contacting. * Binary phase diagrams. * Bubble and dew point calculations. * Binary multistage distillation. * Reflux ratio; total, minimum and economic ratios. * Effect of distillation column sidestreams. * Liquid/liquid equilibria. * Ternary phase diagrams. * Classes of synthetic membranes. * Operation of pressure driven membrane processes. * Membrane fouling. * Membrane module design. |
