Where do you take those inferential models from?

摘要

Charts shown in my editorials,illustrating the performance of select first-principles models,have attracted much e-mail feedback.While mostly positive,some question why the editorials do not provide detail about the principles behind the models.I was taken aback by that criticism because of the distillation inferential models I use: Generalized cutpoint calculations(GCCs)and generalized distillation shortcut(GDS)are well documented in the public literature.Of the reactor models I use,reformer severity(REFS)and visbreaker(VISBS)models are also documented,though not as well.
