Hello!

 

I am working on an atmospheric - vacuum unit. I have converged my crude oil atmospheric tower with its specifications in Hysys v10. How can I install independent every equipment of my subflowsheet (sidestrippers, pumparounds...) obtaining the same results than in the subflowsheet template of Hysys? I want to get it outside the column environment and meet the same specifications for the cuts.

 

I have tried to use Recycles without sucess, please help me and thanks in advance. I attach a screenshot of my simulation. Left-hand my converged subflowsheet and at the right-hand my intent of separate the equipments, top, first side stripper...

 

I need to do it to personalise my plant according to my PFD.

 

Thanks in advance.

Did you try to find an answer at AspenTech's support site? That's where I would start.

1.  Disconnect the downstream of Recycle at the point back to column.

2.  Reconnect the stream back to column when all the unit operations in the reflux loop are converted.

Hi,

 

You can try Flowsheet directory of Column unit operation =>Internal Streams =>Export.

Why would you want to ?  The Column solver is more efficient than building that stuff outside with recycles and adjusts.  If you need to get material or energy streams out of the column subflowsheet for heat integration, you can export the internal streams.
