Sharing Automation Knowledge and Experience

Sharing Automation Knowledge and Experience

I’m always amazed at the wealth of knowledge and experience exchanged in the Emerson Exchange 365 global user community. One example I’ve been following is in the DeltaV Forum, Fuzzy logic control in DeltaV.

Embedded Tools Drive Better Loop Tuning

Embedded Tools Drive Better Loop Tuning

Properly tuned loops are critical to efficient, effective plant performance. However, constant changes in the plant environment mean that proportional-integral-derivative (PID) tuning cannot be a set-and-forget procedure. This poses a problem for many modern plants,...

PID Algorithm ISA Technical Reference

PID Algorithm ISA Technical Reference

At AIChE Spring21+17th GCPS, James Beall presented, An Activity Report on the Newly Formed ISA 5.9 Subcommittee on the PID Algorithm, to address the lack of no standards or technical references related to the Proportional, Integral, Derivative (PID) control algorithm.

Podcast: Process Control Consulting Stories with James Beall

Podcast: Process Control Consulting Stories with James Beall

When the plant is not running the way it should, with excessive variability, alarm conditions or sub-optimized performance, plant engineers often connect with the Emerson Production Performance consultants. I had the opportunity to sit down and record a podcast with Emerson’s James Beall who is a member of the team.

Improving Polymer Reactor Control Performance

Improving Polymer Reactor Control Performance

Emerson’s James Beall presented Novel Techniques to Improve Polymer Reactor Tuning at AIChE virtual conference based on a project he worked on. Reactor control is complex with many interactions between control loops. The way to tackle this challenge is to start by identifying the process dynamics and create a realistic process simulation to identify improvements in the control strategy to address the complexities.

Improving Control Valve Response Specifications

Improving Control Valve Response Specifications

Control valve response is a critical factor in successful control strategies and process variability. In a ControlGlobal.com article, Responsible control valve response, Emerson’s Greg McMillan and James Beall discussed the efforts underway to include valve responsiveness into the ISA 75.25 Control Valve Dynamic Testing standard.

How Does PID Loop Dynamic Reset Limit Work?

How Does PID Loop Dynamic Reset Limit Work?

In the DeltaV discussion forum in the Emerson Exchange 365 community, there is a post, Question about Dynamic reset limit and “Use PV for bkcal” options. What caught my eye was a response by Emerson’s James Beall describing dynamic reset limiting and specifically how it is performed in the DeltaV distributed control system controller.

Learning about Control Valve Performance

Learning about Control Valve Performance

In manufacturing processes with flowing fluids, control valves are among the most important equipment to keep the process operating smoothly and reliably. For those not experienced in their design and operation, AIChE's CEP magazine has a great article, Evaluate...

Distillation Column Automation Control and Optimization

Distillation Column Automation Control and Optimization

The cold section of an ethylene plant is responsible for cooling and purifying the product-grade ethylene, propylene and other bi-products from the cracking furnaces. Cracked gas is cooled in transfer-line exchangers which produce steam from the effluent gas energy. Gas is further cooled with water in the quench column, scrubbed and dried before being compressed in the cracked gas compressor and fed to the cold box.

Applying Embedded Model Predictive Control

Applying Embedded Model Predictive Control

The history of model predictive control (MPC) dates back to the early 1970s invented at Shell Oil and was known as Dynamic Matrix Control. MPC was designed at that time to solve largescale control challenges. As technology advanced, this technology could be more...
