Introduction to Mass Balance: Theory and Basic Definitions
9 Lectures
45:41

Brief Introduction to the Topics we will be studying in this Course

Preview
04:06

Understanding the definition of Process...

A chemical process must have a **chemical reaction.**

Preview
04:47

There are 3 main Type of Diagrams:

- Block Diagram
- Flow Diagram
- Pipe and Instrumentation Diagram

Block and Flow Diagrams will be used extensively in the course...

P&ID are studied in higher level courses such as Plant Design, Automation and Control of Process, etc.

Preview
05:43

Basic Unit Operation:

- Heat Transfer Unit Operation
- Mass Transfer Unit Operation
- Momentum Transfer Unit Operation
- Reaction Unit Operations

Important specially for further courses! Understanding the importance of a Unit Operation in a Chemical Process.

Basic Unit Operations

07:09

Process Variables are essentially variables that will be analyzed to understand the "status" of our system.

Several examples are:

- Temperature
- Pressure
- Density
- Flow rate
- Concentration
- Viscosity

It's important you understand the importance of each of the variables and how the variables are measured.

Process Variables

04:13

Mass flow, Mole Flow and Volumetric Flow

These type of flow rates are the ones that matter to us in Mass Balance.

Please get to know that you can relate them

- Mass - Molecular Weigth - Mole
- Mass - Density - Volume

Mass, Mole and Volumetric Flows

05:27

The State of a System is very important.

There are two types of State that we will be studying in this course

- Steady State: No change of variables with respect of time
- Transient State: properties of the system change with time

System State (Steady and Transient)

07:22

We present other type of System classification

- Open System: Exchange of Matter and Energy
- Closed System: Exchange of Energy but no Matter
- Isolated System: No exchange of Matter or Energy

We also present the type of processes:

- Isobaric
- Isothermal
- Isochoric
- Adiabatic (No heat exchange) we study this in Energy Balance

Other type of Systems (Open, Closed, Isolated)

06:13

** End of Section 1 **

You should know bay far all the basic concepts and definitions for the course.

Be sure to review the material in order to satart Section 2!

Mass Balance Elementary Principles and Equation
26 Lectures
03:56:59

We will see the next topics:

- Mass Balance Principle and Equation
- Mass Balance in 2 Units (No Reaction)
- Mass Balance in 2 or More Units (No Reaction)
- Recycle and Bypass in Mass Balance
- Mass Balance in Reactive Systems
- Chemical Equilibrium in Mass Balance
- Multiple Reactions in Mass Balance

Let's go!

Introduction to Section 2

05:08

Basic Principle of Mass Conservation: No creation or Destruction of Mass!

There is only transformation...

We present an examples so you get the best of the Topic!

Mass Balance Principle

05:22

The Mass Balance Equation is presented:

Inlet - Outlet + Production - Consumption = Accumulation

The accumulation term is generally a derivative... In steady state we will ignore this fact!

Mass Balance Equation

02:51

The Differential Mass Balance is recommended for Continuous Processes (Steady State)

The Integral Mass Balance is recommended for Batch or Semi-Batch Processes (Transient State)

Type of Mass Balances (Differential and Integral)

04:34

The type of Processes are presented once again... We will perform some exercises!

Review: Type of Processes

01:14

Steady State Problem... We see how the accumulation term is cancelled and since there is no reaction the consumption and production terms are cancelled as well!

We will work with Inlet = Outlets

Steady State Problem

07:55

We solve this Batch Problem. Hexane will be evaporated with air. At the end you finish with NO hexane at all...

The accumulation term here is a derivative of mass with respect of time!

Batch Problem

09:57

How to read and draw Flow Diagrams.

Its very important to be able to read the diagrams and get information and data that will help you understand the process.

If you get written data or any type of extra data, is very important that you draw the diagram and write down every data! Then you should be able to solve you problem!

Diagram Flow Construction

10:54

Its very important to be able to scale-up and scale-down. This is done generally by calculating a Factor.

Basis of calculation is important to establsih on "what base" is the problem based?

Scale-Up & Basis of Calculation

13:06

We analyze our first system: A system with no reaction, in one single unit!

Mass Balance in Non-Reactive Systems with 1 Unit

05:20

We apply the Mass Balance Equation to this example of Water and NaOH. The idea is to dilute the original Brine to a less concentrated one.

Example of a Non-Reactive Systems with 1 Unit

09:00

Sometimes you are going to stumble upon a problem with not enough data and you will ask yourself if you either need more data or if you just made a mistake.

We start this study of "Degree of Freedom". This methodology allows us to know if the system is completely set or if it has some degree of freedom (i.e you can set the variables)

Can the Problem be Solved?

03:58

We use the "variable counting" vs. "equation couunting".

Its very important to use INDEPENDENT equations. If you count a dependent equation, the you will not be able to solve the system!

Variable-Equation Counting

08:54

Degre of Freedom Analysis Example. I like this example since you get to see how we apply the method of DOF Analysis.

Important to mark that you should account all the variables, even though you know you have the data. Explicit data such as:

X = 10

is an explicit equation that you should also take into consideration!

Degrees Of Freedom Analysis: Example

03:28

The proposal of this Methodology to attack Mass Balance Equations is totally recommended!

You may use other approaches but they should be similar to these one!

Mass Balance Methodology

06:04

We apply the methodology to an example.

Methodology: Application to a Mass Balance

09:19

EXERCISE#07: Wet Sugar Production

17:24

Dry Air and Humidity (water) are common mixture in ambient air. Normal operations require dry air, therefore the air must be dried.

EXERCISE#08 - Drying of Air with pellets

15:21

Flow of CO2 in a pipeline. We use geometry of the pipeline...

EXERCISE#09 - Flow of CO2 in a Pipeline

12:02

This are basic Mass Balance Problems. We will add up extra "features" to these type of problems such as:

- More Unit Operations
- Recycle, Bypass and Purge
- Reactions
- Combustion

Be sure you get the idea, these set of problems is very important for you to continue in this course!

Mass Balance of Atomic Species and Molecular Species
7 Lectures
01:14:45

So far we've only seen the Mass Balances of Molecular Species (H2O, CO2, N2)... But we could also do Mass Balances on the Atomic Species.

The main advantage is that atoms cant be created or destroyed so they have the form:

Inlet = Outler

Even though there is a reaction occuring in the system!

Mass Balance with Purge Systems
5 Lectures
46:18

As with Recycle and Bypass, we will find convenient for reaction systems to have a purge.

Many systems will not be able to eliminate inert material. The amterial will accumulate in the sytem and this should not be possible!

We are working in Steady State so we need to find a way to mantain the steady State... The Purge!
