PROCESS CALCULATION

FACULTY MEMBER:- Dr. N. ANANTHARAMAN

OBJECTIVE : To make a process flow sheet with mass and energy balances.

1. STOICHIOMETRY:

Introduction- Units and Dimensions - stochiometric principles-composition relations, density and specific gravity.

2. IDEAL GASES AND VAPOR PRESSURE:

Behaviors of Ideal gases -kinetic theory of gases - application of ideal gas law- gaseous mixtures - volume changes with change in composition. Vapor pressure- effect of Temperature on vapor pressure-vapor pressure plots-vapor pressure of immiscible liquids-solutions.

3. HUMIDITY AND SOLUBILITY:

Humidity - saturation - vaporization - condensation - wet and dry bulb thermometry Solubility and Crystallization-Dissolution -solubility of gases.

4. MATERIAL BALANCE:

: Material Balance - Processes involving chemical reaction - Combustion of coal, fuel gases and sulphur-Recycling operations - bypassing streams - Degree of conversion -excess reactant - limiting reactant

5. ENERGY BALANCE:

Thermo chemistry - Hess's law of summation - heat of formation, reaction, combustion and mixing - mean specific heat -Theoretical flame Temperature.
