HP Reliability: To b(ias) or not to b(ias)? This is the question

Petrocontrol: Friedman, Y. Z.

How often would you bias an inferential model? Given the propensity of instruments to go off calibration, "never" is not a valid answer. "Every day upon receiving lab information" is an equally bad an..

HP Control: Where do you take those inferential models from?

Petrocontrol: Friedman, Y. Z.

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 provi..

HP Control: Alkylation product separation control

Petrocontrol: Friedman, Y. Z.

People do not speak much about advanced process control (APC) of alkylation product separation. Why? Precise product separation is crucial to alkylation unit economics. Alky reactor effluent is separa..
