Subject Description

Introduction to chemical engineering flowsheet calculations, including material and energy balances, unit systems, and real gas and vapour behaviour predictions. Systems of units and unit conversion; concept of conservation of mass is developed as the basis for determining mass flows in chemical processing systems. Material balances around single process units, and groups of units, involving simple systems and recycle streams, and non-reacting and reacting systems; component, elemental balances. Gases, liquids and vapours; ideal and real gas behaviour; use of compressibility factor and generalised compressibility factor charts; vapour pressure estimation; humidity. Concept of conservation of energy is developed as the basis for determining energy flows in and around chemical processing systems; evaluation of enthalpy changes with and without phase change; simplified energy balances for batch, steady-state and adiabatic systems; estimation of heats of reaction, combustion, solution and dilution; energy balances in reacting systems; simultaneous material and energy balances.
