Haryana polytechnic syllabus trade CHEMICAL ENG Paint Tech 3rd sem /CHEMICAL PROCESS

Haryana polytechnic syllabus trade CHEMICAL ENGINEERING (Spl. Paint Tech) 3rd semester / subject CHEMICAL PROCESS CALCULATIONS for the session 2012-13 and you can read the syllabus as well as download from here.

The subject provides the knowledge of materials and energy requirements for a process and with this knowledge raw material requirements for a given process can be calculated.


1. Introduction (8 hrs)
Dimensions, Units, Physical Quantities like density, pressure, volume, force, power, energy, temperature, heat in SI, CGS, FPS and MKS. Numerical problems related to interconversion in different system of units. Definition of mole, mole fraction, mass, mass fraction, molality, normality, molarity and simple numerical problems.

2. Behaviour of Ideal Gases (10 hrs)
PVT relationships, standard conditions, partial pressure and pure component volume. Gas laws: Boyle’s law, Charles law, Dalton’s and Amagat’s law, Ideal Gas equation, Equation for real gases i.e. Vanderwall’s equation, simple numerical problems, relation calculation of composition, average molecular weight and density.

3. Material Balance (10 hrs)
Concept of material balance, types of material balance, material balance for unit operation with bypass, recycle and purge, simple numericals based on material balance without chemical reactions and with chemical reactions.

4. Energy Balance (14 hrs)
Concept of energy balance, Forms of energy, Definition of :
– Exothermic and Endothermic Reactions
– Standard Heat of Reaction.
– Heat of Combustion
– Heat of Formation.
– Heat Capacity
– Cp and Cv
Calculation of:
– Standard heat of reaction from heat of formation and combustion data.
– Heat of reaction at constant pressure or constant volume
– Heat of reaction at a temperature from standard conditions i.e. 25C

5. Combustion processes (6 hrs)
Simple definition of
– Excess Air
– % Excess Air
– Air fuel ratio
– Theoretical O2 required
– Analysis of products of combustion

Emphasis should be laid on problem solving in all the area of material and energy balance. Simple practicals relating to wet bulb temp, dry bulb temp and humidification chart should be done. Students should be encouraged to make flow sheets for various processes. This well help the students to understand the subject better and solve intricate problems in various areas.
