Chemical Engineering Fundamentals

One of the most significant steps in process design is driving engineering drawings and diagrams. This video aims to deliver useful information about:

• Overall view of engineering drawings and diagrams and

• How they are used, read, and developed

Block flow and Process Flow Diagrams which are shown with abbreviations of BFD and PFD are used in the preliminary design section of the plant. In this video, you will learn:

• The main components of BFD and PFD;

• How they are developed and

• Their difference between BFD and PFD and the points which make them special

Piping and Instrumentation Diagrams (P&IDs) are used to illustrate the details of plant design where all data on BFD and PFD are transformed into them with a more comprehensive design. This lecture aims to:

• Give comprehensive knowledge about P&ID and its difference from other drawings;

• Show what things are and are not illustrated over this diagram and

• Why it is important?

Knowing which drawings are essential and where to use them ensures that, you can now go for developing the various drawings. In this chapter, you will learn:

• How to develop various drawings including, BFD, PFD, and mainly P&ID;

• Revising them with some letters to show in which stage they are and;

• Updating them if anything is needed to add, or is wrong over the diagram which is shown with different colours

Cause & Effect Diagrams are also types of engineering drawings that should be mentioned separately because these diagrams are essentially different from other drawings that you have already learned about. This video aims to deliver:

• The difference in Cause & Effect diagrams;

• Their importance in Risk Assessment and

• Utilization conditions and procedure

Go back and see what way you have walked through and which improvement you made during this journey. You now have a practical and very useful knowledge of Process Engineering which will make you different from others. After learning the most essential drawings of process engineering, we can go over other drawings that are mostly used in other disciplines. In this video, you will learn about:

• Other drawings and where they are used;

• Which disciplines use them and;

• How they can input for process engineering design and calculations

Chemical and Physical properties of materials and how they are affected throughout the various processes are worth-considering in chemical engineering. In this video, you will learn:

• Chemical and Physical properties in detail;

• How to distinguish chemical and physical properties and

• Intensive and extensive variables by working on the example

After successfully distinguishing the physical and chemical properties, we can go over two essential physical properties that are molecular weight and density. This lecture aims to give brief information about:

• Calculating molecular and average molecular weight;

• Density for gaseous and liquid mixtures;

• How the relative density and API gravity are calculated

In the previous lesson, you have learned how to calculate the density for gaseous mixtures and faced one of the most significant factors for gases which is the compressibility factor. While you have opened up the topic, in this lecture we will cover:

• What is the compressibility factor and how is it calculated?;

• Compressibility factor for natural gases and;

• Viscosity and its calculation

While we are talking about physical properties, it is significant to mention some variables that are related to the topic of heat and energy. You will understand it better in the next section where you will learn about material and energy balance in detail. This session is dedicated to:

• Specific heat capacity and its calculation;

• Thermal conductivity and Fourier law and

• Thermal conductivity for liquids, gases, and mixtures

If you are in this course, you already know the necessity of pressure, especially vapor pressure. There is a classic and specific definition for vapor pressure that you can see everywhere, but it should not be a general explanation of this phenomenon. In this lecture, you will get into:

• Pressure and energy relationship;

• Meaning of vapor pressure both for liquids and mixtures and

• The relationship between temperature and vapor pressure by working on Antoine's equation

Material/mass balance can be regarded as the process design basis that is used to determine the quantities of raw material and products produced. This video covers valuable information about:

• The procedure for mass and material balance development and

• Their application in different industrial processes and equipment in detail

When carrying out mass and material balance, it is important to know the basic principles behind conversion and yield which affect the balance. In this lecture, you will:

• Learn the importance of conversion and yield and

• Understand their definitions and usage in a given problem

One of the main topics that should be known by process engineers and will be applied in the design and calculations sections is Thermodynamic Processes. In this video, we will:

• Carefully analyze thermodynamic processes that do affect the working principle of the process equipment;

• Acknowledge the difference among various processes;

• Address the disparity between heat and temperature and

• Specifically, open the meaning of expansion and compressions

Since we have made a background in previous, we can take a step to go over energy balance. As it was mentioned for mass and material balance, energy balance is one more essential topic that should be analyzed by engineers. In this lecture, you will learn:

• The procedure for energy balance development;

• The effect of the law of Thermodynamics on energy balance;

• Enthalpy calculation and

• Their application in different industrial processes and equipment in detail

Enthalpy is the main part of carried energy balance because the amount of heat in a system has a significant effect on our process.

This video is dedicated to giving a descriptive explanation of:

• Types of heat and their characteristics

• Enthalpy calculation methods

There are some other factors that have a considerable impact on energy balance and therefore the operation in process equipment. This video is dedicated to Heat of the mixture, reaction, and formation and aims to deliver:

• The information about their concept and importance and

• How to calculate and implement them in energy balance

In this video, you will perfectly apply what you have learned in previous lectures by working on a specific example in the distillation column.

Take this advice for your better understanding: Please try to understand the process scheme first, then take notes about what should be done for this problem and watch the video till you understand how to carry out material and energy balance in any industrial process.
