Course

Unit I

Introduction to process calculation – dimensions and systems of units – fundamental quantities of units, derived quantities, definition and units of force, volume, pressure, work, energy, power, heat-unit conversions in FPS, MKS and SI systems.

Unit II

Mixtures and solutions – methods of expressing compositions of mixture and solutions, wet and dry basis concept. Ideal and real gas laws Gas constant normal molal volume, calculations of pressure, volume and temperature using ideal gas law. Gas mixtures Use of partial pressure and pure component volume in gas calculations. Dissociating gases. Relation between mole%, volume% and pressure% of ideal gases calculation of average molecular weight, density, mole%, weight% in gas mixture in SI/MKS systems applications of real gas relationship in gas calculation.

Unit III

Description and simple material balance calculation of physical processes such as drying, distillation, absorption, mixing, crystallization, Evaporation.

Unit IV

Single stage material balance calculation of leaching and extraction, calculations involving recycling and bypassing operation – limiting reactant, excess reactant, conversion, yield and selectivity – simple numerical for finding yield, conversion and composition.

Unit V

Calculation of material and energy balance based on reactions involving heat capacity and specific heat- mean heat capacity of gases – heat capacity of gas mixture and liquid mixture. Calculations of heat capacity by integral equation up to three terms – sensible and latent heats of fusion, sublimation, vaporization. Calculations of standard heat of formation from heat of combustion data. Calculations for heat of reaction from heat of formation and heat of combustion data Fuels – calorific values proximate and ultimate analysis – air requirement and composition of flue gases.
