How does it look like that we collaborate to create a Spheripol production site model? We can pick a case example and reproduce the production plant mass balance with your help. Please let's give it a try.

We can start with Aspen Polymers - Spheripol Hi-Impact Polypropylene Model, which is a document in the public domain (https://www.researchgate.net/profile/Junior-Lorenzo-Llanes/post/How_to_define_polymers_on_aspen_plus/attachment/5fcae17fd6d02900019bad5a/AS%3A965193702055947%401607131519676/download/Spheripol+High+Impact+Polypropylene+Copolymer+Process.pdf).
According to the document: "The process configuration, operating conditions, and equipment sizes are based on the report Polypropylene Update Supplement C from SRI
Consulting [Process Economics Program Report 128C] (SRI Consulting is now a division of HIS – go to www.ihs.com to order the report). Some aspects of the model were drawn from the Spheripol Plant Operation Manual, interviews with engineers from operating companies, and patent literature."
In this document, I think that we'll have all the information needed.
The report mentioned above says that: "The evaluation was based on a single-line plant capacity of 400,000 mta propylene impact copolymer."

This is an excellent idea, as if we model tsuch two units, we can reuse the calculations for actual production assets when we do not know better.
So let's start with creating virtual assets.

I was thinking that we'll model a general unit, but the idea is to inform which unit we are modeling? I worked in two units: one with a capacity of 400,000 mta, producing only homopolymer, and the other with 250,000 mta, producing homo, random, and copolymer.

It is very clear Aguiar, I downloaded that file with all the details. Now it is about the logic of adding data into the platform and turn it into information. We have several sections: entities, products, processes and technologies, sites. The Spheripol process is already described in the technology section, the information from this report may then help to create a production site's model, but this study does not specify what the actual production unit is. Insuch a case the best we could do is to create a virtual production plant, tht would be not much usefull least we reuse this model for existing production facilities.

The Spheripol Plant Mass Balance – SRI Report 128C has all information. How can I send you an image of the table? Besides, there is an example in Aspen Plus that can provide more details.

Thank you Aguiar.
We already have a simplified technology description associated to this communication thread, so that the question is: can we improve this description based on this report?
Otherwise, the idea would be to make production plant models, but then we have no clue about which Spheripol plant the report is about? Worstcase we can create a virtual production plant with its mass balance.

I'll take a close look to see if I can find something in the public domain. I have a lot of information, but due to my confidentiality agreement, I need to act with discretion.

Aguiar, this is precisely how ppPLUS works, by using only public domain data or proprietary data approved for sharing by the data owner. Looking forward for your feedback.

Hi Dr. Nicolas,
It's an exciting idea. I have a broad view of the data we'll need to perform the mass balance, but I'll appreciate any help.

Thanks a lot Aguiar,
Is there a Spheripol unit you are familiar with, for which you know the mass balance details and that can be considered public domain, so that we can use these data to create a production plant model with its mass balance?
