Mass Balance Course

MB0

Chemical Engineering


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%!
