CH3351 Chemical Process Calculations Syllabus:

CH3351 Chemical Process Calculations Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 To enable the students to acquire knowledge on laws of chemistry and its application to solution of mass and energy balance equations for single and network of units and introduce to process simulators.

UNIT I

Base and derived Units – Composition of Mixture and solutions – 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 II

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.

UNIT III

Calculation of absolute humidity, molal humidity, relative humidity and percentage humidity – Use of humidity in condensation and drying – Humidity chart, dew point.

UNIT IV

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.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

UNIT V

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 – Application of Process simulators in energy and material balance problems.

TOTAL: 45 PERIODS

COURSE OUTCOMES:

On completion of the course, the students would be able to
 Understand the concepts of dimensional consistency and effective application of units and dimensions.
