Chemical Engineering Thermodynamics

• Use an Equation of State to calculate PVT-properties for a pure compound
• Derive expressions for fugacity, enthalpy and entropy from an Equation of State
• Perform process calculations for refrigeration units and liquefaction plants
• Optimize a multistage compression process
• Parameterize a vapour pressure equation and similar from experimental data
• Use, and account for, the requirements and limitations the fundamental laws of thermodynamics impose on a given proces.
• Choose thermodynamic models for liquid- and vapour mixtures with the aim of calculating phase equilibrium
• Account for the assumptions behind the choice of models
• Perform simple vapour-liquid equilibrium calculations for multicomponent mixtures using activity coefficient models, as well as equations of state
• Choose models for calculation of liquid-liquid and liquid-solid equilibria and perform such calculations
• To determine model parameters by regression of experimental equilibrium data for mixtures.

Tools for calculation of physical properties, including residual properties, from Equations of State and from generalized method are developed by means of spreadsheets. These tools are used for designing processes for cooling and for liquefaction of gasses. Finally, the physico-chemical model description of fluid mixtures is essential for most separation processes. The course deals with models for the excess properties of the liquid phase and their application for simple phase equilibrium calculations for gas-liquid, liquid-liquid and liquid-solid systems.
