Fundamentals Of Chemical Engineering :
** Features of organized chemical processing- from Chemistry to Chemical Engineering, Chemical Industry- scope, features & characteristics.

** Unit Operations in Chemical Engineering – an overview.
** Units and Dimensions – Systems of units, Conversion of units, Dimensional homogeneity and consistency, dimensional analysis, dimensionless groups and their use in chemical engineering.

** Process Variables – mass, volume, pressure, temperature, chemical composition, flow rates. Single Phase Systems: Solids, liquids, ideal gas and real gases; Equations of State; Compressibility factor charts; estimation of densities and heat capacities of solids, liquids and gases, and their mixtures, Mixing Rules e.g. Kay’s Rule.

Multi-phase Systems:
** Outlines of unit operations involved in separating multiphase systems – distillation, crystallization, absorption, adsorption, extraction, leaching, evaporation, drying etc.;
** Single-component phase equilibrium – phase diagrams, estimation of vapor pressure using Clausius-Clapeyron Equation, Cox Charts and Antoine Equation, Gibbs’ Phase Rule;

** Gas-Liquid Systems – saturation, saturated/ superheated vapor, humidity, psychrometric charts, boiling point, dew point, bubble point, degree of superheat, Raoult’s Law and Henry’s Law for multi-component
** gas-liquid systems; Solutions of solids in liquids – solubility and saturation, phase diagrams;

** Immiscible and partially miscible liquids – miscibility and distribution coefficients, phase diagrams for ternary systems.
** Process Data Representation and Analysis – interpolation and extrapolation, curve-fitting and least squares method, fitting a line to scattered data.

Chemical Process Calculation :
Concepts of chemical similitude and scale up, Material balances: Fundamentals;
** Batch and flow processes, Steady-flow and unsteady processes, material balance calculations for single-unit and multiple-unit processes, material balance for reactive and non-reactive systems, processes with recycle and/or bypass with or without purge, material balance for combustion reactions, unsteady-state and transient processes.

Energy balances :
** Introduction to energy balances, energy balances on closed and open systems – the steady-flow energy equation, mechanical energy balances, tables of thermodynamic data. Energy balances on nonreactive processes – state properties and hypothetical process paths employed for their estimation, energy balances for phase change operations, heat of mixing and heat of solution – energy balance for mixing and dissolution processes.

** Energy balances on reactive processes – heats of reaction, measurement and calculation of heats of reaction – Hess’s Law, formation reactions and Heats of Formation, Heats of Combustion, Energy balances for combustion reactions – adiabatic reaction temperature, theoretical flame temperature. Combined material and energy balances including some typical industrial problems.
