Course Content (Syllabus)
MASS AND ENERGY BALANCES
Material balances and definitions. Simple flow sheets. Combustion and excess air. Elements of phase equilibria. Equations of state. Critical and reduced T and P. Compressibility factor (Z). Pure gases and gas mixtures. Partial pressure. Humid-ity; steam tables; drying and humidification processes. Energy balances. Defini-tions (work, heat, energy, enthalpy, specific heat). Enthalpy calculations. Phase change and ΔH calculations. Generalized energy balance. Enthalpy of reaction. Reactions at T, P other than standard. Enthalpy of dilution and of mixing. Com-bined mass and energy balances. Distillation. Degrees of freedom. Enthalpy – concentration diagrams. Humidification – dehumidification – cooling diagrams. Applications. Non-steady state mass and energy balances. Simple non-steady state mass balances, mixing, distillation, reaction. Simple non-steady state energy bal¬ances, heat transfer. Simple applications and examples.
Students are required to attend a computer lab on the use of Aspen Plus. Students are required to submit 2-3 project reports. They count 20% in final grade. Esti-mated time per project, about 10 hours. A mid-term exam is optional, and counts 30% in final grade
