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” […]

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 […]

Connectivity, Productivity and Efficiency Benefits of IIoT Depend on Integrated Cybersecurity

  I had a discussion with Gary Freburger, president of Schneider Electric’s process automation business, about the Industrial Internet of Things (IIoT). He framed the discussion by introducing a new concept, “intelligize.” Simply put, intelligize means establishing a method to sort, prioritize, and refine your data, to connect bits of data so they become meaningful […]

Managing the Cybersecurity Threat to Hazardous Process Plants

  Managing the risk of hazardous process plants is a difficult and resource-intensive activity. In order to reduce costs and improve productivity as technology evolves, process plants employ new equipment and techniques that introduce new hazards. Over the past few decades, the process industries have almost entirely shifted from control systems that were either analog […]

Webinar Recording: Drivers for Cloud SCADA Operations

  Alternative solutions around virtualization, cloud and mobility are becoming more stable, reachable and cost-competitive to a larger number of industrial SCADA end-users, both large and small. These advancements, along with ever-increasing requirements for a more efficient and cost-effective solution, are leading businesses to look to the cloud as a viable resource. Additionally, the Industrial […]
