01. Lesson 1.01: Course Introduction

Hello everyone. Welcome to the course. The name of the course is Gas Transmission, Compression and Cooling. Before I go through the course, I'll give you some information about myself.

02. Resume

I have over 44 years of technical, industrial, operational, and research experience in the oil and gas industry. I have taught many engineering, especially gas engineering courses in different universities and trained a large number of professionals in major oil and gas companies throughout the world. I received my BSc from Abadan Institute of Technology in Iran and my Masters and PhD from the University of Manchester and Cambridge in England, all in chemical engineering. I also spent 2 years at the University of Calgary, Alberta, Canada as a visiting professor, and have trained a large number of professionals from different oil and gas companies in gas transmission and gas compression. I have worked with many engineering societies, including ASME, APEGA, IPC, Chem Eng Science, and have published a large number of technical papers in prestigious technical journals. I published a book called "Pipeline Design and Construction, A Practical Approach" with two of my colleagues in the year 2000. The revised third edition was published in 2007 by ASME Press. This book is taught at many universities and is being applied by professionals at different oil and gas pipeline companies.

03. Course Content & Skills

So I would like to talk about the course content and skills that the participants learn in this course. The first chapter is about the gas composition and gas quality, which talks about the composition of natural gas in gas transmission lines; quality of gas, sweet and sour gas, lean dry natural gas, gas molecular weight, gas gravity, Wobbe index, higher and lower heating values.

04. Course Content & Skills (2)

And then the skills to learn or improve in this chapter I can talk. Improve the knowledge of the participants to better understand the API standards for the quality of natural gas in gas transmission lines. To learn the definition of the terms and some of the calculation methods.

05. Course Content & Skills (3)

The next chapter talks about gas transmission. Flow of gas in large transmission lines (transient and a steady state condition). We talk about the gas flow equations, comparison and applications. And then impact of gas and pipe parameters on pipeline flow efficiency, pipeline looping, packing, drafting, and many practical examples that I give you during that chapter. We talk about pipeline codes for high-pressure gas transmission lines and also pipeline cost of service, optimization model, and J-curves with many application examples.

06. Course Content & Skills (4)

The skills that the participants learn or improve in this chapter are to improve their skills to enable the participants to design gas transmission lines. To learn how to improve the pipeline efficiency. To learn the impact of different pipe and gas parameters on the flow. To improve the knowledge of cost analysis in gas transmission lines.

07. Course Content & Skills (5)

This chapter will be followed by the gas compression. The function of a compressor station on long transmission lines. Why we add a gas compression system on the gas transmission lines. An overview of different types of gas compressors. Thermodynamics of gas compression. Then we talk about head, actual flow, power, compression ratio, speed, thermal efficiency, performance curve, which is very important for the designers and for the gas controllers or the wheel map. They call it wheel map, and the other stuff that is coming after that in gas compressors. I give lots of examples, especially I give you real examples to demonstrate the process design and compressor evaluation for installation on large gas transmission lines. Impact of ambient condition on the performance of gas compressors. Fuel calculation and flow optimization on line compressors. Practical examples to help the participants to better understand the function/operation of gas compressor on large transmission lines.

08. Course Content & Skills (6)

And the skills to learn and improve in this chapter: Why gas compressor stations are used on gas transmission lines. The process design of gas compressor stations. To learn the gas compressor wheel maps and to better know about how it works. To learn of how compressor performance curves can help gas control department in moving gas in transmission lines.

09. Course Content & Skills (7)

The next chapter is about the gas coolers. Because you have the transmission, then it comes the gas compressor and then you have to add aerial or gas coolers. Function of gas coolers on gas transmission lines. An overview of aerial coolers and their structures. Removal of heat from hot gases in aerial coolers. Governing heat transfer equations. Components of a bay of gas cooling. Economics of gas coolers. Modeling and evaluation for the installation on gas transmission lines.

10. Course Content & Skills (8)

What you learned in this chapter is why gas coolers are added to transmission lines. To learn or improve the knowledge of air cooled systems. To improve the knowledge of simulation software. Learn about cost optimization and learn about operation of gas coolers.
Thank you for joining me. In the next lesson, we're going to talk about gas quality and gas composition.
