Anyone tried the COCO process simulator ver 2.7? 

 

I just started exploring this CAPE open environment non- commercial software, which may be useful for educational purposes.

 

Website is at:

 

www.cocosimulator.org

 

Example files are freely downloadable and can be run after installing the free software as mentioned on the website.

 

In particular, the steam and power (CHP) model was interesting.

 

If you have tried it, please share your experiences.  

 

Thank you,

I have seen it, but never used it. But I have used a distillation simulator from ChemSep which is integrated with COCO. Just one run with hydrocarbons, but it matched HYSYS results.

according the documentation COCO includes a free version of Chemsep which I have tested,

the main feature is probably the rate based model developed by Taylor & Kooijman,

there are many papers discussing the details, for books see for example Separation Process Principles

by Seader, Henley, Roper (chapter 3), the book includes solved problems, a review of features and models  available in Chemsep, Chemcad and Ratefract (Aspen Plus) is included.

The thermodynamic library in COCO should also be based on Chemsep (according the documentation)

there are EOSs, models based on liquid activity etc.

the databank (in free version) includes some hundred chemicals.

I tested Chemsep with the examples included in distribution

and several other test cases (I use a different software, a process library, to solve columns)

the solver in Chemsep works well (without initialization) at low / moderate pressures

allowing a full set of specifications, you can also specify a (limited) number of reactions.
