Content
• Importance WHY?
• Source  Book
• Mass Balance:
– Introduction CH4 50%
– Single Phase CH5 20%
– Multiple Phases CH6 20%
– Transient state CH11 10%

Importance
• Why Mass balance?
– Plant Design
– Equipment Design
– Mass quantity analysis (Raw material, Products)
– $$$ Profit!

Importance

Importance
• Besides… you will need it for the next courses
– Energy Balance (you need mass to calculate the amount of energy)
– Thermodynamics (closed/open continuous systems)
– Separation Processes (mass quantities an concentrations)
– Heat Exchange (similar to Energy Balance)
– Momentum transport (you need it for the mechanical equation)
– Plant design (know quantities of product, reactants, etc.)

Book
• Elementary Principles in
Chemical Processes. Felder,
R; Rousseau, R. 3rd edition.
• Problems to ALL pair
problems are in the
“Problems” Section

Book
• I do recommend:
– Basic Principles and
Calculation in Chemical
Engineering. Himmelblau, D.
7th edition.
– Part 2 (Material Balances)

Mass Balance: Introduction
• Section 1
– Theory: System, Process, Unit Operation, Streams,
Flows, Variables, Flow Diagrams, MB
• Section 2
– MB basics
• 1 Unit MB; 2+ Unit MB
• MB with/without reaction
• MB in Combustion
• Purge, Bypass & Recycle
– Theory + Problems + Exercises

Mass Balance: Single-Phase
• Section 1
– Theory (phases)
– Liquids, Solids
• Section 2
– Gases = P,T,V dependent!
• Ideal Gas
• Real Gases
– Cubic Equations
– Z compressibility factor
– MB with gases

Mass Balance: Multi-Phase
• Section 1
– Single Phase Theory (Phase-Diagrams)
– Vapor Pressure (Antoine and Clapyeron Eqn)
– Gibbs Phase Rule
• Section 2
– Gas-Liquid Systems (1 condensable)
• Evaporation, Drying, Humidity
– Gas-Liquid Systems (multi-condensable)
• Raoult Law, Henry Law
• Dew/Bubble points
• Txy Diagrams
• Section 3
– Solid-Liquid Systems
• Solubility and Colligative Properties

Mass Balance: Transient State
• Section 1
– Theory
• Accumulation concept
• When apply Transient State MB
• Cases and examples
• Section 2
– Exercises
• Integral Balances
• Mass Balances
• Computer solved

Basic Concepts you need…
• Mathematics
– Arithmetic (+,-,*,/)
– Geometry (area, perimeter, volume, etc)
– Conversion of Units (cm to m, kg to g, etc.)
– English System vs. International Systems
– Decimals and scientific notation
– % and fractions

Basic Concepts you need…
• Chemistry, Physics
– P vs. F
– Temp (abs) vs. Temp (R, F, K, C)
– T vs. Q
– Mass =/ weight
– Mol, Mass Weight, molar mass, mass fraction,
mole fraciton,
– basic chemistry kinetics
– stoichiometry

End of Introduction
• You should be now getting an idea of MB!
• Hopefully:
– You are good at math and analytical skills
– You like chemical processes
– You are PATIENT
– You practice a lot of problems!
• Theory alone will not help
– As introductory course to ChemEng, its SUPER important
to learn 100%!
