Comments: JP End Point, Kero 95%, Kero Freeze Point, JP Flash Point, BGO CFPP, Molex 10% and Kero Flash Point were infered. The predictions even from difficult inferences like FlashPoint, CFPP and Freeze Point were quite good. This is demonstrated by the fact that in almost all the cases no laboratory or analyzer bias update was needed even though all the inferentials were used for online control. All of the inferential properties except for the cold properties (e.g. freeze point) were based on sidestream cutpoints. The cold properties required additional density measurement through Watson K factor.
