CHE251A - Introduction To Che And Process Calculation

Objectives and Overview, Historical Perspective of Chemical 2Engineering, Role of a Chemical Engineer, Role of Balance Calculations, Review of Basic Concepts. Steady state Material Balances in Non reacting Systems: on Single 4Units, Basis of calculation; number of independent equations, Development of Degrees of Freedom; specification of variables. Balances on Multiple Unit Processes: Recycle and bypass. Balances in Reacting Systems: Stoichiometry, multiple reactions, Recycle and Purge. Element (atomic) versus Species (molecular balances): Combustion of Fossil Fuels, ultimate (elemental) and proximate analyses, combustion chemistry in complete combustion, theoretical and excessa1r.Material Balances in Multi pbase Systems: Phase Rule, Gas Liquid Systems, vapor liquid equilibrium (VLE) calculations, isothermal flash vaporization, Immiscible and Partially Miscible Liquid Systems, Solid Liquid Systems; saturation solubility and crystallization.
