Course Description

Course description

This course introduces you to chemical engineering and shows you how common industrial processes such as Steam Methane Reforming, Steam power plants, Cracking of Ethane, Purification of ethanol and several other processes can be simulated using a process simulation software.

 Process simulation is a much needed skill in the Oil & Gas, Chemical, Petrochemical and Energy industry. Build Industrial Chemical Processes right there on your computer and see what effect a change in some of the Process Conditions would have on the yield of the process.

This is a fully hands on course.

How the course is set

This course is designed for anyone with a little knowledge of Chemistry and an interest in Simulation of Industrial Chemical Processes. Each section has lectures dedicated to covering the required theoretical background to the course and also has screen videos to show how the process of interest is simulated using the COCO process simulator software. We would not just discuss chemical processes, you would actually build these processes by yourself.

External resources such as video animations, YouTube videos and Wikipedia pages which would make the concepts taught easier to understand are also included in the external resources section. Since this course is designed to give you a practical skill which you can use in the workplace, there are lots of quizzes which gauge your ability to use the software.

The first section teaches some of the basic concepts you would need to be able to model chemical processes such as an Introduction to Chemical engineering, Unit operations and the Concept behind process simulation. The lecture which covers thermodynamics would be coming soon.

The second section shows you how to get your PC set up for this course.

The remaining sections of the course focuses on using the process simulation software COCO to model various chemical processes in a hands on manner.

This video shows how the Steam power plant process can be simulated using COCO. You are advised to try to simulate the process by yourself first before watching this video.

1 question

A power plant generates 90Kg/s of steam at a pressure of 86bar and a temperature of 773.15K,
this steam goes through an expander which converts the fluid internal energy into rotational
energy which is used to turn generators and produce electricity. The discharge from the expander
enters a condenser at a pressure of 100KPa where it is converted to saturated liquid. The
condenser removes energy from the process stream at a rate of 7.287×108KJ/h, in order to
change the expander discharge into liquid. A pump pressurizes the liquid leaving the condenser
to a pressure of 86bar and sends it to the boiler which converts it to steam at a temperature of
500C for power generation.
If the efficiency of the expander and pump is assumed to be 75%, what amount of energy would
be produced from the plant through the expander?
What would be the energy requirement of the pump?
What would be the heat duty of the reboiler?

Pure Ethane at a temperature of 298.15K and pressure of 1 bar is compressed to 4bar and heated to a temperature of 998.15K before it is fed into a plug flow reactor. Ethane decomposes at this reaction condition to ethylene and hydrogen. The decomposition reaction is first order with respect to ethane with rate constant 0.2533s-1 (3), if the molar flow rate of ethane into the reactor is 16.67mol/s, and the reactor tube diameter is 0.0706m and has a length of 100.2m, what is the pressure of the product stream and the mole fraction of ethylene in the product stream.

A mixture of ethanol and water (Ethanol 37%, Water 63%) at a temperature of 25*C and pressure of 101.325KPa is fed into a distillation column. The distillate is expected to come out with 83% ethanol and 17% water while the bottom should contain nothing more than 10% ethanol.

If the column is modelled using 20 stages, what would be the flowrate and process conditions of the distillate and bottoms?


05:54

The distillation process is examined in this screen video.

Distillation of ethanol water mixture

13:46

´Carbon dioxide from a fermentation process at  a pressure of 2atm and a temperature of 25ᵒC contains 30 mol percent ethyl alcohol. The alcohol needs to be removed by contact with water at 25*C and 2 atm. The gas flow rate is 400 lbmol/h and that of the water stream is 2000 lbmol/h. Determine the compositions of the streams leaving the absorption column if you model it with 10 stages, and what is the amount of ethanol recovered?

11:46

The result of the gas absorption process is examined in this lecture. The component splitter unit operation is also added to the flowsheet.

05:10

The distillation columns are fine tuned and the simulation ends here.

Article

You are to build this process by yourself, feel free to use the material in the external resources when in doubt.

Styrene is produced from Ethyl benzene by subjecting ethyl benzene to a high temperature of 880K at a pressure of 1.36atm. The product leaving the reactor contains a mixture of ethyl benzene, styrene and hydrogen. Styrene is the desired product and hydrogen (byproduct) needs to be recovered. The stream leaving the reactor is cooled to a temperature of 343.15K in a cooler which brings about a drop in pressure of 20000Pa; this liquefies the styrene and benzene, making it easy for the hydrogen gas to be separated out in a flash separator. The liquid portion coming out of the separator is sent to a distillation column which has 33 stages. Ethyl benzene is recovered at the top of the column while styrene is recovered at the bottom. The product quality required is 99.5% purity Styrene.
What is the composition of the stream leaving the reactor?
What is the amount of hydrogen gas separated in the flash separator?
If the distillation column has 33 stages, with the feed entering on the 15th stage and the condenser and reboiler operates at 110KPa and 120KPa respectively, what would be the product flowrate and process conditions of Styrene and Ethyl benzene leaving the distillation column?
Molar flowrate of Ethyl benzene = 152.2mol/s
Equilibrium constant for the chemical reaction at 800K = 22392.825Pa

Section 5: Putting it all together (Haber process)
10:34

Olabode Alamu, Freelance Process Design Engineer.

I hold a degree in Chemical engineering from the University of Lagos with extensive experience in the field of Process engineering. My expertise in Process engineering extends from working as a Facilities Engineer in a Natural Gas Plant, to working as a Process Design Engineer in a leading Engineering design firm. 

At the moment, I am a graduate student of Subsea Engineering at the University of Houston with research interests in Subsea processing and design of Subsea equipment.

I am passionate about teaching, I have taught process simulation to lots of undergraduate students over the past three years. 

I belong to a team- Spunt Innovatia which is committed to delivering excellent engineering training to people around the world. We believe in providing people with the necessary engineering skill set they need to succeed at their career.

The course 'Simulation of Chemical engineering processes using COCO' was a spin off from a project that was started by the faculty members (Dr. Daniel Ayo, Dr. Tolu Ajayi and Dr. Akinjide Akinola) of the Department of Chemical engineering at the University of Lagos. 

I hope you enjoy the course just as much as I enjoyed putting it together.
