HP Control: Process control practice renewal 2010
Allan Kern, Zak Friedman and I have offered numerous ideas to strengthen the practice of process control.1-4 Allan Kern inaugurated a fundamental assessment of process control engineering practice in ..
HP Viewpoint: Engineering Earth's thermostat with CO2?
Earth's temperature is a chemical process system. Review of control system engineering of Earth's thermostat with anthropogenic CO2 in 1997 proved it will never work because it is an unmeasurable, uno..
HP Control: APC for min maintenance or max profit? - Part 2
While I have promoted proper control system performance indicators18–25 since 1964, like Dr. Y. Zak Friedman,1 I also am aware of some deeper problems with realizing its full commercial potential..
HP Control: APC for min maintenance or max profit? - Part 1
First, thanks to Dr. Y. Zak Friedman1 for referencing my July 1997 HP editorial.2 I commend him for using HP publications from more than a decade ago in his editorial. While I appreciate Dr. Friedman'..
HP Control: Align alkylation separation to economics
A recent HP editorial1 showed the effect of advanced process control (APC) with inferential models on alkylation isostripper iC4 lost to an nC4 side draw (Fig. 1). From trend data for the two periods ..
Align HPI operations to economics
Clifftent optimizes risky tradeoffs at limits
Set vapor velocity setpoints profitably
Use Clifftent principles to account for operating limit tradeoffs and risk to substantially improve financial performance
Demise and keys to the rise of process control
Modeling the penalty for violating constraints as well as modeling the credit for approaching them, and shared-risk shared-reward business practices are the solutions
