COCO (AmsterCHEM) • Normal volume flow computation

2024-03-01T13:43:47+00:00

Dear Jasper,

I'm facing issues with the computation of the normal volume flow in my simulation. Indeed, the measured normal volume flow does not give the same value as the normal volume flow that I compute, using the total molar flow and the ideal gas law.
It is especially obvious after a mixer, as you can see in the attached file.
How can this be explained ?

Thanks for your help.

Best Regards,
Savinien

COCO (AmsterCHEM) • COFE Flowsheet protection

2024-02-15T11:46:02+00:00

Hello,

I would like to protect a COFE Flowsheet, so that the users cannot modify the Flowsheet (modify feed values and unit operations parameters, plug-unplug streams...). Is there a way to do so ?

Alternatively (it would be even better) I was thinking to put my Flowsheet in a COFE Flowsheet Unit Operation, so the users could only modify some inputs to this Unit Operation. But I would like to protect this Unit Operation, so the users cannot open it to see the details and of course cannot modify it. Is it possible to do it in COFE ?

Thanks in advance,

Savinien Pertant

Python Unit Operation (AmsterCHEM) • COM thermo_Python UO in Aspen Hysys V11

2023-11-20T15:15:36+00:00

Hello,
I have a problem in the implementation of the Python Unit Operation in Aspen Hysys V11. In particular when setting the COM thermo property package, and selecting the CAPE-OPEN 1.1 for the vapor and for the liquid, the following error occurs (FIG_error) independently from the selection (Default, Hcgas or Simple). Does anyone know what I’m doing wrong?
Thank you in advance

We are happy to announce release 3.7 of COCO. Since 3.6, the following improvements were made:

Redesign of the Unit Operation edit dialog, including connected stream table,
Additional mass balance diagnostics at flowsheet solution,
Resizable main window for the JUIcE icon editor,
Improved formula parser,
Alternate row colouring in in-flowsheet tables,
Customized representation of absent compounds instream reports and flowsheet report,
Several work flow improvements

For a full list of changes, please visit the COCO web site. COCO 3.7 is available for download from the COCO web site, or run COCO UPdate (CUP) to receive the update.

COCO (AmsterCHEM) • solver problem when using Chemsep property package

2023-07-26T08:54:10+00:00

Hello,

am trying to solve a flash separator in a flowsheet. since Tea doesnt include the PSRK EOS, i used chemsep prperty package for the inlet Stream of the flash. But sadly when using the chemsep property package with the PSRK the solver doesnt find a solution.
I actually would like that all the streams in the process to work with the PSRK EOS but this seems impossible.

In many cases i am facing quite difficulties with the solver, am trying to model a recycle flow with a Splitter, if i want just to change the inlet feed streams ( x10 the amount) the solver stops finding solutions. Is there any smart settings to use.
please take in considereation that i am not a COCO expert.

Best regards
Ghadi
