The post Tuning the Model Predictive Control of a Crude Distillation Unit first appeared on the ISA Interchange blog site.
Abstract: Tuning the parameters of the model predictive control (MPC) of an industrial crude distillation unit (CDU) is considered here. A realistic scenario is depicted where the inputs of the CDU system have optimizing targets, which are provided by the real-time optimization layer of the control structure. It is considered the nominal case, in […]
The post ISA’s Future Is Quickly Approaching, and Industrial Cybersecurity Will Play a Critical Role first appeared on the ISA Interchange blog site.
We are just getting into 2018 and some of us are already planning our summer vacation. Time passes quickly and the years go by so fast; it reminds me to reflect on the past and plan for the future. Like so many ISA leaders, I have benefited from ISA membership. I have been able […]
I recently surveyed the on-site development of the control system for a large concentrated solar power station. This “first of a kind” facility offered many control challenges, such as balancing heat in 600-meter-long vaporizers, setting the dry-out point, and adjusting the mirrors’ position at centimeter precision on a 50-meter distant target. In this “research-oriented” […]
The post AutoQuiz: What Is the Best Location in an HMI for the Graphic Display of a Distillation Column? first appeared on the ISA Interchange blog site.
Today’s automation industry quiz question comes from the ISA Certified Automation Professional certification program. ISA CAP certification provides a non-biased, third-party, objective assessment and confirmation of an automation professional’s skills. The CAP exam is focused on direction, definition, design, development/application, deployment, documentation, and support of systems, software, and equipment used in control systems, manufacturing […]
The post Webinar Recording: How to Document Safety Instrumented Systems Inspections and Tests first appeared on the ISA Interchange blog site.
Calibration professionals are very often asked to perform inspections on instrumentation. This ISA webinar recording focuses on best practices of inspecting, testing and documenting a safety instrumented system as well as how to apply these practices in the field to not only SIS, but also to simpler instruments, such as valves.
The post DCS Upgrade: How to Reduce Stress During Execution first appeared on the ISA Interchange blog site.
The Reliance Industries Hazira complex, which manufactures a wide range of polymers, polyesters, fiber intermediates, and petrochemicals, needed to determine the best way to update the industrial automation system. The complex commissioned a naphtha cracker plant in March 1997 using then state-of-the-art technology, including a UNIX-based control system. Over the years, there had been […]
