UNIT II

IDEAL GASES AND VAPOUR PRESSURE

9

Ideal gas law, Dalton’s Law, Amagat’s Law and Average molecular weight of gaseous mixtures. Effect of temperature on vapour pressure, Vapour pressure plot (Cox chart), Vapour pressures of miscible and immiscible liquids and solutions, Raoult’s Law and Henry’s Law.


UNIT III

HUMIDITY AND SOLUBILITY

9

Partial saturation, Humidity- Absolute Humidity, Vaporization process, Molal humidity, Relative and percentage saturation, dew point, humid heat, wet bulb and dry bulb temperatures, use of humidity charts, adiabatic vaporization and adiabatic saturation temperature.

UNIT IV

Combustion of coal, fuel gases and sulphur – Recycling operations – Bypassing streams – Degree of conversion – Excess reactant – Limiting reactant- Selectivity and Yield.

UNIT V

ENERGY BALANCE

9

General steady state energy balance equation, Heat capacity, Enthalpy, Heat of formation, Heat of reaction, Heat of combustion and Calorific values. Heat of solution, Heat of mixing, Heat of crystallization, determination of ΔHR at standard and elevated temperatures, Theoretical flame temperature and adiabatic flame temperature.

TOTAL : 45 PERIODS

OUTCOMES: On completion of this course the student will
• Have clear idea of various types of unit systems and they will be able to convert units from one form of the unit to other.
• Have sound strategy for solving and developing mathematical relations for material and energy balance calculations for reaction and separation processes.
• Analyze the behaviour of recycle processes, performing approximate material balances by hand and setting up calculations for rigorous solution by computer.
