thank you very much Dr. Sajid! Can you please explain more why the Hot Pump Around must have the same composition as the feed to the heat exchanger's shell side? couldn't it just be steam?
Thank you for your feedback. I am glad this is helpful. To your question, we aim to save energy (and ultimately the energy cost) in the system. The hot pump around the stream is nothing, just the raw crude stream, but at different operating conditions. After passing through a heat exchanger, a hot pump around the stream transfers its energy to the stream containing raw crude and water, and a cold pump around stream is returned back as (cold) raw crude into the system. I hope this clarifies.
Thanks for the video ! when u add the add the water stream at the begining the composition is given in mole fraction ? shouldn't it be given in mass fraction as mass flow rate is given?
Hello Dr. Zaman, first of all thank you for your valuable video. I have a question that if I want to create a new simulation or rescale this simulation to a different crude oil flow rate, how do I decide the side draws flow rates and pump around rates?
Thank you so much Sir for your value sharing. I am emailing you regarding the Aspen Hysys File and the pdf file of the data. Hope to get your responding soon. And Hope you have the simulation instruction for predict dew point, pH on OVHD of Atmospheric Distillation, Sir.
Hello Dr Sajid, thank you for your useful efforts. I need to simulate this process for my junior project. Is it possible to get this HYSYS file and the DATA so I can do it myself? I'm struggling to find the right and complete data. How to obtain this pdf? And if you can kindly provide your email. Thank you in advance.
Hi, I want to ask If you want to compare the design results with actual data for the desalter tool, what do you need to pay attention to? and is it possible to find out the results of the reduced salt content in this hysys design?
hello dr, i'm trying to do the simulation just like what you do But the iterations take forever. I wonder why, because when it comes to distillation, it always turns like that.
Diesel fuel is a general term that includes various fuel types used in diesel engines, including AGO. Meanwhile, AGO refers to a specific type of diesel fuel mainly used in automotive applications. You can see in this simulation that a major difference is sulfur content. AGO generally has a higher sulfur content than other diesel fuels. I hope this helps you.
@@drzamansajid Yes, after a closer inspection of product parameters are also noticed the differences in densities, temperature range, and viscosity to name a few. Your feedback was insightful, thank you!
You need to select hypothetical components and then click on Method. There are two options (Create and edit hypos and Create a batch of hypos). You can choose any one of them. Let's choose the second one. Then specify the range of boiling points and click on Generate Hypos. HYSYS will generate all pseudo components within the boiling range you entered. You can add all into your component list unless you know which ones you need. You can also double-click on the name of pseudo components to see details. It will allow you to enter any further information about the pseudo component if you have any. I hope this helps.
@@africanmelito892 Please watch my other video lectures to learn this. On the tab of the component list, next to Add button, there is a tiny arrow; click that, and you will see an option to define a hypothetical component. My explanation may vary depending on the version of HYSYS you are using. I hope this helps.
there is no naphtha component in aspen hysys, what should i do or where can i find specific properties needed? do u have any materials that could help me in simulating? it would be of great help to me as a student who's taking plant design course this term 🥹 thank you, doc!
@@peachyshan7169 you can define it hypothetically. Here is the link of a lecture which will teach you how to find built-in HYSYS models. I hope this helps. th-cam.com/video/q0rnoX6o4lY/w-d-xo.html

Hi, I want to ask
If you want to compare the design results with actual data for the desalter tool, what do you need to pay attention to?
and is it possible to find out the results of the reduced salt content in this hysys design?
You will need to watch and compare critical parameters.
hello dr, i'm trying to do the simulation just like what you do But the iterations take forever. I wonder why, because when it comes to distillation, it always turns like that.
That's because you have the system over-specified. Just make sure you have DOF = 0 before running the simulation. I hope this helps.
What is the difference between the Diesel product and the AGO product? as far as I understand they are interchangeable terms
Diesel fuel is a general term that includes various fuel types used in diesel engines, including AGO. Meanwhile, AGO refers to a specific type of diesel fuel mainly used in automotive applications.

where we find the file ? thnx
Please send me an email and I will share.
Hii sir.
I had run the simulation almost 2 times, but while running it says diseal stream data is insufficient
I don't know what the issue is with your simulation until I look at that. Please ensure your degree of freedom is zero.
How can i get calculation PDF and hysys fiel???
You can email me and I can share these files with you.
Please I want to work on motor oil and I don’t know if it’s possible to find it in aspen or how to generate it

Yes, if you do not have it in HYSYS, you can define it as hypothetical. I hope this helps.

Yes, you can. If I recall correctly, there is a built-in example of the same or similar system in HYSYS. You may look at that.
