REFS (GASOLINE REFORMER SEVERITY)

AN INFERENTIAL MODEL PACKAGE, PREDICTING BOTH THE FEED PNA (PARAFFINS, NAPHTHENES, OLEFINS), AND THE PRODUCT QUALITIES: REFORMATE OCTANE, % AROMATICS, RVP, ETC.

Reformer severity models are available in the industry. However, these models require feed PNA (paraffin, naphthenes, aromatics) characterization. That is a weakness since no refinery performs feed characterization in real time, or even daily, the models use outdated feed characteristics and their octane or aromatics prediction is off.
To avoid the problem of unavailable input data, Dr. Friedman has developed REFS, an inferential model that infers feed PNA from unit conditions. This feature renders REFS suitable for real time octane or aromatics control without the use of an analyzer. REFS has been implemented on many semi regenerative and continuous catalyst circulation units, for gasoline or aromatics manufacture.
