Description

Welcome to the **Single Phase Mass Balance** Course!

I designed this course is for general engineering fields. **Chemical and Process Engineers** will find it very relevant for their study curriculum but even Mechanical or Industrial Engineers will find it very interesting!

By the end of this course **you will learn**:

The definition of Phase is explained. Single-Phase problems are those that only have 1 Phase (either liquid, solid or gas)

Phases Theory

03:39

This Section covers solids and liquids. Since their densities are almost independent of temperature and can be considered constant, we pay special attention on this concept.

Solids and Liquids are very common phases in the industry!

Ideal Gases and Mass Balances
25 Lectures
03:38:23

A brief introduction to Gases, its importance in engineering and why it is harder to model

Gases

02:55

We present the Ideal Gas Model which is very important. You probably have already worked with it...

Ideal Gas Model

04:14

The typical limitations of the Ideal Gas. High pressures and low temperatures... the more near the molecules, the more interaciton they have and therefore, more non-ideal they became

Ideal Gas Limitants

02:20

Why we model with Ideal Gas. We explain the application to Mass Balance Solving

Why Ideal Gas in Mass Balance?

01:49

An applied example of the Ideal Gas Law

Ideal Gas: Example

04:25

Standard Conditions are conditions for a Standard Use. Typical values of T, P and V varies dependeing o n the industry or institution.

Standard Conditions: Temperature and Pressure

02:27

SCMH is a "standardized" or "normalized" measurement of gases flowing in pipes. They give a reference value and comparable to other streams if they where on the same conditions

Standard Cubic Meter per Hour (SCMH)

06:30

Examples of the use and application of the Standard Conditions of Temperature an Pressure AKA STP

Standard Conditions: Example #1

03:36

Another example on how we can apply the SCMH concept

Standard Conditions: Example #2

02:25

Last example of STP

Standard Conditions: Example #3

03:53

Mixture of substance in gas phase are very common. Even though they are separate substances, they are still in one phase (gas phase). We apply the partial pressures and Ideal Gas in order to model such mixtures.

Ideal Gas Mixture: Partial Pressures

04:55

We finally apply the concepts seen in this sections to a Mass Balance. Get the idea of how we could model data. We get T, P and form there we get moles!

Example of Ideal Gases in Mass Balance

Real Gases (Theory)

06:41

Definition of a Real gas. That gas that can not be modeled with ideal gas law

Preview
01:37

The Critical Point is a sepcial point. In this point the liquid and the gas are no longer separable. The gas has superfluid properties and the liquid has also superfluid properties

Critical Point

02:28

Reduced conditions are a type of "standardization" in order to compare substances. The reference is the critical point conditions such as Temperature and Pressure (critical)

Reduced Conditions

01:38

Its very important to remark the difference between gas and vapor. Esentially is the critical point that makes the difference.

Mass Balance with Real Gases
20 Lectures
02:42:24

A common model for a Real Gas. This uses "virial" terms. It is good for pressure or temperature modeling. Its difficult for volume model due to the amount of volume terms.

Preview
05:46

An example of how to apply the Truncated Virial Equation. Remember that by theory, the virial equation is infinite. You should choose the number of terms you are going to work with.

Preview
05:39

Other Equations may be used. The Scope of this Course is only to:

- Virial Equation
- Z compressbility Factor

You may study other equations in typical courses such as Thermodynamics

Other Equations

00:09

This video introduces the concept of compressibility factor "Z". This is essentially just a direct correction to the ideal gas law. This is easy and very powerful!

Compressibility Factor (Z)

01:09

A fast example of the compressibility factor "Z"

Example: Compressibility Factor

01:09

For some diatomic molceules, it is better to apply a correctino factor named by Newton. This should be done since they are some times very important and will correct your predictions

Newton's Corrections

00:28

We present the compressibility chart for each substance. It show "Z" value for every substance, T and P

Compressibility Chart

01:52

If we get ONE compressibility chart that applies to every single substance, would be awesome wouldnt it?

We could use the law of corresponding states which help us get ONE chart of Z values vs. T and P!

Law of Corresponding States

05:53

A compressibility factor "Z" example

05:16

How do we model Real Gases in mixtures? We must use the Kay Rule which is easy to understand but it takes a little bit of time to calculate...

EXERCISES#16 - Compressibility of Oxygen and Newton Correction

08:59

As with previeous example, we apply Z factor to Nitrogen Purge system. Remember that Nitrogen is a diatomic molecule, therefore we apply Newton's Corrections

EXERCISES#17 - Nitrogen Purge System

19:43

We "evaporate" the Liquid Nitrogen. Due to conditions, we can't model this as an ideal gas. We use Z-Compressibility Factor
