Process Control
HP Control: Where do you take those inferential models from?
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..
Predicting important parameters using artificial neural networks
Consider them for complex nonlinear processes

HP Control: Alkylation product separation control
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..
