Module Delivered in 1 programme(s)
Module Coordinator: NIALL MORRIS
Module Author: NOEL DUFFY
Module Description: This module develops students' capability to solve real phase equilibrium separation problems, applying fundamental theory with industry-grade software. Advanced functions of the steady-state process simulation package, Aspen Plus, will be covered and the students will be introduced to the capabilities of a batch process simulator.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Assess the applicability of correlative and predictive phase equilibrium models to specific ideal and non-ideal system separations.
LO2 Assess the separability of a non-ideal mixture using Aspen software.
LO3 Construct sensitivity analyses, design specifications, calculator blocks and optimization blocks in Aspen Plus
LO4 Prepare a simulation of a batch process using batch simulation software.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
Co-requisite Modules
No Co-requisite modules listed

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.

Module Content & Assessment

Indicative Content
Review of vapour liquid equilibrium (VLE) for ideal systems.
Vapour pressure of pure components: Antoine equation. Pxy, Txy, yx diagrams for ideal mixtures; K-values; relative volatility; bubble and dew point calculations; isothermal and adiabatic flash calculations.
Non-ideal phase equilibrium
VLE in non-ideal systems: using equations of state; using activity coefficient models with equations of state. Variation of activity coefficients with temperature; local composition (excess Gibbs energy) models: Wilson, UNIQUAC, NRTL. Azeotropes. High pressure systems: retrograde condensation.
Highly non-ideal systems (VLE, GLE, SLE)
Liquid-liquid equilibrium; variation with temperature and pressure. Supercritical components; solubility of gases in liquids, gas-liquid equilibrium. Introduction to electrolyte solutions: Debye-Huckel Law, modifications: Bromley, Pitzer; Chen NRTL electrolyte model. Introduction to solid-liquid equilibria: salt solubility, influence of salts on vapour-liquid equilibria.
Predictive methods for phase equilibrium
Local composition models - group contribution methods: UNIFAC and modified UNIFAC. Predictive equations of state: PSRK and VTPR-GC methods. Strengths and weaknesses of such methods. Introduction to COSMO and PC-SAFT models. Semi-predictive NRTL-SAC for drug solubility prediction.
Data quality assessment
Checking phase equilibrium data for thermodynamic consistency. Regression of published experimental data to models. Examination using alternative databases e.g. Aspen, NIST, Dortmund DataBank. Combination of data sources and predictive methods.
Application of phase equilibrium to separation processes
Azeotrope variation with pressure. Non-ideal ternary systems: nodes, saddles, residue curves, distillation curves, distillation boundaries. Determination of feasible product compositions. Determination of operating pressure.
Advanced Capabilities of Aspen Plus
Sensitivity analysis, design specifications, calculator blocks and optimization blocks
Batch Simulation Using Batch Process Developer
Determine cycle time and identify bottlenecks, create a multiple batch Gantt chart, generate equipment content and capacity reports to determine equipment size.
