Complete Design Process of a Non-Isothermal CSTR Made Easy

🎉 Reactor design is a core element of being a chemical engineer, it is one of the most interesting but often challenging aspects of chemical engineering. 💯
✅ In this detailed tutorial, we look at the full derivation of the Mass Balance design equations and Energy Balance design equations for a Continuous Stirred Tank Reactor CSTR. We will cover all types of configurations from the simple Isothermal CSTR to the Non-Isothermal Adiabatic CSTR and the most difficult Non-Isothermal Non-Adiabatic CSTR.
🎉 After this tutorial, you will be able to design any CSTR with ease and express both in terms of concentration and more importantly conversion! 💯

This is exactly what I was looking for, I have just begun reactor design at university so please keep uploading this stuff and I am going to need it :)

[@TheChemEngStudent]

Thank you for your kind words!

[@sarahwebb2323]

Super is all i can say, you make that look so easy, like how OMG!

[@TheChemEngStudent]

Thank you! Cheers!

[@ChemEngWeekly]

Step by step and clear as always! A great video on CSTRs 👏

[@stewartrobinson1018]

I couldn't agree more!

[@alexdenny7339]

I believe this is residence time, I can't believe I was the first to win! Like getting an extra 6K is a lifesaver for me at uni, so everyone get entering, I am hoping for second time lucky :) haha!

[@TheChemEngStudent]

Thank you for your kind words! You are most welcome Alex I hope it goes towards something positive! Good luck!

[@garykielpalaciosespinoza4719]

It was a great video. Always clarifying my doubts. Greetings from Peru!!! My answer is residence time.

[@TheChemEngStudent]

Thank you for your kind words, much appreciated. Its great to hear from international students, glad you found the tutorial helpful, and thank you for your entry to the competition. Winner will be announced on the 5th of October on our Facebook page! Good Luck!

[@stewartrobinson1018]

I agree wih Kerr, I have just begun reactor design and this has been super helpful. I think the answer is superficial velocity!

[@TheChemEngStudent]

Glad it was helpful!

[@kerrferguson4725]

Another great video sir - and perfect timing :) My answer is Residence Time

[@TheChemEngStudent]

Thank you, glad it was helpful! Thank you for your entry. The winner will be announced on the 5th of October on our Facebook page! Good Luck!

[@mohammedarif1380]

May God bless you for this wonderful video tutorial!

[@TheChemEngStudent]

Thank you glad it was helpful!

[@derekneil9870]

Residence time!

[@TheChemEngStudent]

Thank you for your answer, good luck!

[@StephanieWood-r5z]

This was really helpful for me

[@TheChemEngStudent]

Thank you for your kind words!

Can you specify what you mean by flow rate? For example, molar flow rate, mass flow rate, volumetric flow rate etc.

[@TheChemEngStudent]

The flow rate can be represented in either format, this is really dependent upon the information available to you. However, if we are talking primarily on the reactor input and output, they should be in moles, since those are the units we must use when modelling reactors. I hope this helps, thanks for watching!

You messed up several Things in the energy balance. You say ΔΗrxn. In what temperature Tref Tin or Tout? You just copy paste you don’t understand what you are doing

[@TheChemEngStudent]

I'm sorry you feel that way, however I am not sure I understand what you mean. As I am sure you are aware the nomenclature for carrying out these balances can vary, and so this is my preferred method. In regard to the temperature points I don't fully know why you mean as following the systematic process it does make sense. I would ask you to please reframe from derogative statements on this channel. If you would like to discuss things further, please do send me an email and I would be happy to speak further on this.

[@panagiotisathanasiou7918]

@@TheChemEngStudent In What temperature is your ΔΗrxn. It is a simple question. Your systematic process is just copy paste.
