AIM
Every chemical reaction involves consumption of Materials and energy. The reactions
are to be balanced with correct quantity of materials and energy to achieve good
percentage of conversion for products. The aim of this course is to give fundamental
knowledge on such material and energy balances.
OBJECTIVES
To make them understand different types of laws of chemistry of materials and also
prepare the students to accurately calculate the Stoichiometric relations between the
materials involved in a physical and chemical reaction.
UNIT I UNITS AND DIMENSIONS 5
Basic and derived units, use of model units in calculations, Methods of expression,
compositions of mixture and solutions.
UNIT II GAS CALCULATIONS 7
Ideal and real gas laws - Gas constant - calculations of pressure, volume and
temperature using ideal gas law. Use of partial pressure and pure component volume in
gas calculations, applications of real gas relationship in gas calculation.
UNIT III MATERIAL BALANCE 7
Stoichiometric principles, Application of material balance to unit operations like
distillation, evaporation, crystallisation, drying etc., - Material balance with chemical
reaction - Limiting and excess reactants - recycle - bypass and purging - Unsteady state
material balances.
35
UNIT IV HUMIDITY AND SATURATION 7
Calculation of absolute humidity, molal humidity, relative humidity and percentage
humidity - Use of humidity in condensation and drying - Humidity chart, dew point.
UNIT V FUELS AND COMBUSTION 6
Determination of Composition by Orsat analysis of products of combustion of solid, liquid
and gas fuels - Calculation of excess air from orsat technique, problems on sulphur and
sulphur burning compounds.
UNIT VI THERMO PHYSICS 6
Heat capacity of solids, liquids, gases and solutions, use of mean heat capacity in heat
calculations, problems involving sensible heat and latent heats, evaluation of enthalpy.
UNIT VII THERMOCHEMISTRY 7
Standard heat of reaction, heats of formation, combustion, solution, mixing etc.,
calculation of standard heat of reaction - Effect of pressure and temperature on heat of
reaction - Energy balance for systems with and without chemical reaction. - Unsteady
state energy balances.
