You have obviously asked a good question and are apparently on the "cutting-edge" since no one has made an attempt to answer your question.

Your are correct in your assessment that feed characterization is critical for not only an FCC but any refinery RTO application. I'm not sure a single analysis is going to give you all the information you need to characterize the feed. Your most likely solution will be to find something to measure that you can then use to "look-up" the feed characterization from a "library of feed characterizations" that you have compiled by detailed analysis.

Feed characterization is a huge undertaking and I know from my Shell days that they had a whole army of people responsible for crude characterization.

Hopefully, you don't have too many crudes (ie different types) to run through. Of course, being an FCCU will mean that you will have to be a little more creative in that you could recieve many different cuts throughout the refinery.

Sorry I don't have the experience to represent one certain type of analyzer. I will check around and let you know if I here anything.

Good luck.
