HP Control: Automation: The path to reliability
Consider the view looking back from 2020. Will the current decade be the decade of process automation? This may seem a puzzling way to frame the question. We have been automating for several decades. ..
Safety instrumented function design reduces nuisance trips
Implementing low-cost best practices can provide peace of mind
HP Control: Reshaping process control: A corporate prerogative
Prior to the 1980s, process control was in the dark ages. Our main “technology” was the single-loop controller, despite that it operated obliviously to the many interactions and non-first or..
HP Control: Lose the pyramid (and find process control success)
Most people would classify multi-variable control—or advanced process control (APC)—over the past 20 years as a “slam dunk” in terms of process control, automation and optimization..
HP Viewpoint: Advanced process control: Optimization or control
After 20 years of advanced process control (APC) praise, a reckoning is now taking shape, with some challenging questions, such as: What happened to the original vision of “true real-time optimiz..
HP Viewpoint: Weighing on dual-temperature control
I’d like to weigh in again on the continuing debate regarding distillation column control.1–4 Attention has now turned to the practicality of “dual temperature” control,which is th..
HP Control: Continuous improvement or core-competency?
In the past decade or two, the concepts of key performance indicators (KPIs), continuous improvement, core-competency and best practices have received a lot of attention. What are the relationships be..
HP Control: Back to the future: Process control in 2010
Where will process control money be spent in 2010? The choices include field instruments, safety systems (SISs), control system upgrades (DCSs), multivariable predictive control (MPC) and decision-sup..
HP Control: More on APC designs for minimum maintenance
Perhaps Zak Friedman struck the perfect balance in his series of editorials,1 because while Dr. Latour thinks Zak went too far in his suggestions to prune multivariable control (MPC) matrices,2 I woul..
