JNTUK B.Tech Chemical Process Calculations gives you detail information of Chemical Process Calculations R13 syllabus It will be help full to understand you complete curriculum of the year.
Learning Objectives
- The subject of chemical process calculations is intended to make the students understand mainly the calculations involved in material and energy balances of process units. The students will be trained to
- understand and correctly implement unit conversions in process calculations.
- understand and apply theoretical knowledge towards problem solving.
- analyze and solve elementary material balances in physical and chemical processes.
- analyze and solve elementary energy balances in reactive and non-reactive processes.
- formulate and solve combined material and energy balances.
- realize the relevance of thermodynamics in process calculations.
- carry out complex process calculations using MS Excel.
UNIT-I: Stoichiometric relation: basis of calculations, methods of expressing compositions of mixtures and solutions, density and specific gravity, Baume and API gravity scales.
Behavior of Ideal gases: Kinetic theory of gases, application of ideal gas law, gaseous mixtures, gases in chemical reactions.
UNIT-II: Vapor pressure: Liquefaction and liquid state, vaporization, boiling point, effect of temperature on vapor pressure, Antoine equation, vapor pressure plots, estimation of critical properties, vapor pressure of immiscible liquids and ideal solutions, Raoult’s law, Non-volatile solutes.
UNIT-III: Humidity and Saturation: Relative and percentage saturation or dew point, wet bulb and dry bulb temperature, use of humidity charts for engineering calculations.
UNIT-IV: Material balances: Tie substance, Yield, conversion, processes involving chemical reactions. Material balance calculation involving drying, dissolution and crystallization. Processes involving recycles, bypass and purge.
UNIT-V: Thermophysics: Energy, energy balances, heat capacity of gases, liquid and mixture solutions. Kopp’s rule, latent heats, heat of fusion and heat of vaporization, Trouton’s rule, Kistyakowsky equation for non polar liquids enthalpy and its evaluation.
Thermochemistry: Calculation and applications of heat of reaction, combustion, formation and neutralization, Kirchoff’s equation, enthalpy concentration change, calculation of theoretical and actual flame temperatures.

Out Comes: A student who successfully completes this course will be able to
- learn all background information/charts/datasheets required to carry out process calculations. Some of these are vapor pressure correlations, latent heat correlation, steam tables, psychrometric charts, enthalpy-concentration diagrams etc.,
- formulate and solve simple and moderately complex process calculations associated to industrially prominent chemical processes and technologies.
- conceptualize an integrated methodology that encompasses the knowledge in other subjects (Physical Chemistry, Thermodynamics and Mathematics) and MS Excel for a systematic and structured approach towards chemical process calculations.
- analyze chemical processes through the power of modeling and computation. These include back-calculation methods, inventory losses and revenue related assessment etc.
