Design and Performance Analysis of Distillation Column using Aspen HYSYS | Part - 2 | Lecture # 20

Learn to simulate and design the rigorous distillation column in Aspen HYSYS, and to do the performance analysis by varying various parameters i.e., % tray efficiency of the column. The problem statement is given below:
A feed mixture consisting of 0.05 wt. % ethane, 0.56 wt.% propane, and 0.39 wt. % n-butane is fed to the column at 17 bar, 78.7 °C, and at a flowrate of 1000 kg/h. Specification/parameters of the column:
1. Number of Stages = 75
2. Feed Stage = 50
3. % purity of top Product = 88 mole% propane
4. Reflux Ratio = 3
5. Column pressure = 16 bar
6. Condenser type = Total Condenser
7. Tray Efficiency = 70%
Do the performance analysis of the distillation column.

Great follow up, making videos in series to make a brilliant connection concepts. Great job 👍👏

[@zeeshanshoaib7212]

Haris you are doing a great job dear!!

[@aspenchemchannel]

Thanks bro.

[@wasaysepicworld8246]

Thanks for such a wonderful tutorial

[@usmanismail4130]

Thanks for this. Well explained

[@Rivoj_]

Thank you bro very clear

[@aprilianisetyawatisudibyo492]

Sir, I have a question. I have distillation tower with a top and product spec, also overhead vapour rate spec. But my column can not converge bcs the top spec and overhead vapour rate don't meet the spec that I defined. I have already check the feed condition, but I still don't know the problem's root. How can I solve this, Sir? Thank you~

[@OlusegunJ]

Can we use shortcut distillation on this type of multicomponents to get our data for the rigours distillation column?

[@aspenchemchannel]

Yes we can use. I have already performed short-cut distillation for the separation of multi-components in Aspen Plus. Please watch Lecture # 52 and 53.

I have a pre flash column which having a fired heater as a reboiler, I need to know how can I define reboiler flow, go to add spec then which option I select?

[@qadeermalik9784]

Sir plz provide the link for free setuo of HYSYS.

[@aspenchemchannel]

Dear Qadeer The link is provided in the description of Video # 2.

​​@@aspenchemchannel Dear sir I have install a cracked version of Aspen v10 but I can't use rigorous model of heat exchanger as explained in lecture 16 and I can't find the download link in lecture 2 So can you please reupload the link in your channel

[@icedmocha5264]

can you show for a packed column too?

[@aspenchemchannel]

Sure

Hello , Tnx for video . Please Read and Help Mate !!!!! I need little help. i have a problem with my feed after reactor and distillation tower. feed to reactor is 399k and i wanna go down to 350k , i am using duty stream to loss by 89kw as given information to me but temperature going down till 395k . how can use heat loss in reactor ?? Second : in distillation i have 2 spec about mole fraction , RR and 2 duty for condenser and reboiler . as given information i should specification 2 mole frac but i have no idea about RR and dutys and ref temp in reboiler , how they would effect ? i am using hysys.

[@aspenchemchannel]

You can use energy stream to reduce the temperature to 350K. Connect energy stream to the reactor, and then specify the outlet temperature of the reactor, which will provide you the value of heat. Regarding distillation, if you have any two values from RR, Duty, Mole fractions, you can solve the column. Untick RR and vapor mole flow from specifications, and add specifications of mole fractions required in the product.
