Dear All,

We are in a process of purchasing a process simulation software for our company (Aspen/Unisim/Aveva Process Simulation/ Pro/II etc). However, we need to go in competitive basis for selecting the best software.

For that we need to define scope of work so that all parties can offer their software.
Has any one came across similar SOW that he can share with us?

Also what criterias shall we emphasize on for selecting the best software?

Note: Our plant is ammonia & urea production plant

You should add VMGSim to your list.  http://ebs-group.net...timization.html

 

ChemCad is also a  good simulator. https://www.chemstations.comIt seems like for such a small operation, one copy should be enough. You can get a free trial copy from some of these. You probably will buy based on price.

 

I have used HYSYS for many years and find it easy to use. I have used it for many processes. If you don't have any skilled users, you will want to inquire about training classes. Good luck

 

Bobby

In the past, I did a comparison of different simulations tools for a specific new area of application.

Start with contacting the several software houses asking for a technical presentation of their capabilities in the your specific field of interest. Ask them a commercial quotation too.

Then create a comparison table of the various options, highlighting differences and pros & cons of the alternatives, drawing some conclusions. Do not forget to test them, not only from a perspective of results, but also from the easiness of use.

This should be enough to make a choice.

 

I think Aspen Plus, HYSYS, UniSim, PRO / II, VMGSim, BR&E ProMAX are all viable options.

Carefully decide what it is it to want to model and what the success criteria is, and what data you will check it against.  What will it be used for?

 

e.g.

 

1. Is your aim offline steady state or dynamic?

2. With or without kinetics?

3. Online with real time optimisation?

4. Rigorous Heat exchanger modelling or simple UA?

5. Detailed Tray Hydrualic modelling?

5. Could an AI based model give better accuracy in key areas than a purely thermodynamic based model?

 

If you don't specify what it is the aim and purpose of the model you'll get widely varying feedback from vendors. (also try to talk to technical people from the vendors rather than only sales folks).
