Chemical Engineering Fundamentals

Understanding the engineering disciplines can be a nice step to get into Process Engineering, while only knowing the theories, calculations and some other related operations do handle the engineers' disciplines. In this video, you will get information about:

• Where can Process Engineers work and what are their duties;

• Various design phases of the project and

• The roles of Process Engineers in these phases

After having a strong introduction to the field by knowing engineering disciplines, the responsibilities of process engineers, and their collaboration with other disciplines, we can go over the different engineering projects. This lecture aims to inform you about:

• The Engineering companies and their classification;

• Various Chemical Engineering Projects such as Brownfield, Greenfield and etc. and

• Which companies are responsible for the implementation of these projects

The last lecture concentrated on the types of projects and companies that are responsible for them. Now in this chapter, you will learn how the chemical engineering projects are organized by looking through:

• Block flow diagram (BFD) modelling as a starting point for projects;

• Transferring all data from BFD into Process flow and Piping & Instrumentation diagrams and

• Preparing information packages to install, design, test maintain the operational requirements for equipment

Process Engineering disciplines, operational requirements, projects, and their organization now lead us to illustrate the necessity of the nature of design in which the chemical engineers develop and evaluate the possible designs to meet the targets of production plants. In this video, you will be provided with:

• The background knowledge about the nature of design and its significance;

• Regulations of all design regions and

• Internal and external constraints that should be considered when designing the process

Process Engineering calculations do play a vital role for any plant which are extremely important to carry out the design phase of a chemical engineering project organization. While talking about engineering calculations, it should be noted the importance of the system of units that will be covered in this lecture by having a look at:

• System of basic and derived SI units;

• Which units are named specially and contributed to various base quantities and;

• Conversion factors that are used to convert U.S Customary units into SI units

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
