The application has lowered the average O 2 by about 0.3 percentage points, which improves boiler efficiency, reduces NO X emissions and subsequently minimizes NH 3 consumption. Additionally, Valmet’s ...

Advanced process control Since their inception in the early 1980s, multivariable model-based controllers have become the technology of choice for implementing APC applications. More than 5,000 ...

In the manufacturing world, the word “retrofit” many times is feared to mean “lost production.” In other words, plants—or at least parts of plants—must be shut down for equipment to be upgraded. And ...

Technology progression within advanced process control (APC) continues to evolve; however, it is the relationship among core APC developments, enabling technologies, and management practices that is ...

Rockwell Automation Pavilion8 Model Predictive Control (MPC) software now empowers engineers to design and execute step tests faster, safer and more accurately. Unlike manual step tests that must be ...

It’s not, “You say ‘tomato’ and I say ‘tomahto.’ ” With advanced process controls (APCs), you either know what they are or you don’t. If you do know, you know they give for-real, money-in-your-pocket ...

The move to accept and implement advanced process and equipment control could transform fab productivity within a few years, which may be critical to the industry's survival, a technologist from ...

Advanced logic scaling has created some difficult technical challenges, including a requirement for highly dense patterning. Imec recently confronted this challenge, by working toward the use of Metal ...

A global processing company identifies plant optimization applications with advanced process control software and finds immediate return on investment. Recent global consumer economic numbers show ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...

AE’s solution enables more direct control of ion energy distributions, better bias power efficiency and less power loss than conventional solutions, all benefits necessary to create increasingly ...

ISA recently published the third edition of Basic and Advanced Regulatory Control: System Design and Application by Harold L. Wade, Ph.D., PE. In this Q&A feature, Dr. Wade highlights the focus, ...
