Aspen Tutorial #3: Flash Separation
Outline:
• Adding a Flash Distillation Unit
• Updating the User Input
• Running the Simulation and Checking the Results
• Generating Txy Diagram
Problem Description:
A mixture containing 50.0 wt% acetone and 50.0 wt% water is to be separated into two streams -- one enriched in acetone and the other in water. The separation process consists of extraction of the acetone from the water into methyl isobutyl ketone (MIBK), which dissolves acetone but is nearly immiscible with water. The overall goal of this problem is to separate the feed stream into two streams which have greater than 90% purity of water and acetone respectively.
In this tutorial we will be building upon our existing simulation by adding a flash separation to our product stream. This unit operation can be used to represent a number of real life pieces of equipment including feed surge drums in refining processes and settlers as in this problem. A flash distillation (or separation) is essentially a one stage separation process and for our problem we are hoping to split our mixture into two streams; one composed of primarily water and acetone and one composed of primarily MIBK and acetone.
Adding a Flash Distillation Unit:
Open up your simulation from last tutorial which you have hopefully saved. Select the Separators tab in the Equipment Model Library.
We will be using a Flash3 separator using a rigorous vapor-liquid-liquid equilibrium to separate our stream for further purification.
Select the Flash3 separator and add one to your process flowsheet. Select the material stream from the stream library and add a product stream leaving the flash separator from the top side, the middle, and the bottom side (where the red arrows indicate a product is required). Do not add a stream to the feed location yet.
You can leave your stream table and stream conditions on the process flowsheet while working through this tutorial or you can remove them and add them back in at the end.
Thanks to the Prof. Rene Overney for the material for these tutorials.

Awsome. Thanks for free education.
You welcome!
ótima Aula
You sir! Are a life saver! Modern hero :P
Thank you!!
I am using Batch reactor to covert hydrocarbons in aqueous solution to high value compounds, and CO2 is a product but some of it dissolved in the water and some of in the gas phase above the solution. how to make a model by aspen to calculate the dissolved CO2 in water and in the gas at equilibrium.
many thanks
Hi! thanks for your video, but i have a question about solid separation.
I can't use the Cyclone separation in my simulation.
I have gas and solid in my stream.
Do you know something about solid-gas separation?
Thanks
thanks for the video but what if the temperature of the inlet stream of the separator is linked (heat exchanger) to the amount of vapor coming out of the flash separator and is therefore unknown? i want to simulate a simple linde hampson cycle, best nikolai
I hope can you help me, but when I run the simulation with srk the temperature of product stream give me 22 F
My gamma graph have me a straight line, not like your graph, what's wrong with my simulation then?
Did you added at least 2 substances? They must show interaction between 2 species at least
First of all, either speak clearly or use subtitles. Your voice gave me headache.🙄

or you find another video to watch? a gun was put to your head or something?
