AutoQuiz: Identify the Function of a P&ID Symbol

  Today’s automation industry quiz question comes from the ISA Certified Control Systems Technician (CCST) program. Certified Control System Technicians calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables.

Design Principles for Complex Process Control

  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” […]

AutoQuiz: What Is the Best Location in an HMI for the Graphic Display of a Distillation Column?

  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 […]

DCS Upgrade: How to Reduce Stress During Execution

  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 […]

Plant-Wide Control Design Based on Steady-State Combined Indexes

  Abstract: This work proposes an alternative methodology for designing multi-loop control structures based on steady-state indexes and multi-objective combinatorial optimization problems. Indeed, the simultaneous selection of the controlled variables, manipulated variables, input-output pairing, and controller size and interaction degree is performed by using a combined index which relies on the sum of square deviations and […]
