    Unpredictable Mother Nature Drives New Sugar Production Process

    American Crystal Sugar produces a lot of sugar in its six factories. The first step in the process is to wash sugar beets, and this creates a great deal of waste mud that has to be properly disposed. Shifting weather conditions – rainier than average seasons – increased the amount of water in the process, which drove the company to increase use of aged polymer that aids in the flocculation process and helps prevent buildup...

    Compressor Anti-Surge Control Value Improvement Practice

    Pete Sharpe Author: Pete Sharpe An ethylene plant has a number of very large, very critical compressors which will cause the entire plant to shutdown if they ever trip. The cracked gas compressor increases the entire cold-side feed from around 3 psig to ~475 psig, typically through 5 stages. The two refrigeration compressors are the next biggest compressors that can also shut down the entire plant if they trip...

    Modernization of DCS and PLC with Electronic Marshalling

    Scott Ross Now, with many control systems being 30+ years old, most of these legacy systems have been placed in to end of life or retired lifecycle status. This means no further factory support is available. I caught up with Emerson’s Scott Ross about some of the choices that must be considered moving forward. Manufacturers and producers face options whether to modernize to a newer family of distributed control systems...

    Migrating Legacy PLC-5s to DeltaV

    Way back in the mid-1980’s, when I was a newly-minted engineer working oil & gas production projects offshore in the Gulf of Mexico, a new series of PLCs came on the scene to replace the Allen-Bradley PLC-2’s we had been using. They were the PLC-5 series. Javier DeLuna Now, more than 30 years old, the CPUs used in these PLCs were placed into end of life status which meant no further factory support for the CPUs as...

    Security for Safety System Logic Solvers-Physical Key Switches and Software Locks

    Sergio Diaz Author: Sergio Diaz As a product marketing manager for DeltaV safety instrumented systems (SIS) , I have been asked a few times why the key switch on the CHARMs Smart Logic Solver (CSLS) does not control the lock state as is common with many safety controllers. DeltaV CHARMs Smart Logic Solver (CSLS) The next question is, “Why does the user still need to lock the CSLS via software?” The reason is...

    Cybersecurity Considerations in Safety Instrumented System Architectures

    Sergio Diaz Alexandre Peixoto Safety instrumented systems (SIS), which are designed to take the process to a safe state in trip conditions, come in several architectures with the basic process control system (BPCS). The SIS and BPCS can be totally separate, interfaced or integrated, yet separate. While the debate on which approach is best has been going on for a long time, what are they cybersecurity considerations...

    Controlling Surge in Centrifugal Compressors

    Centrifugal and axial compressors can experience a potentially destructive condition known as surge. Emerson’s Mikhail Ilchenko describes it for me. Mikhail Ilchenko Surge is a condition that occurs in compressors when the amount of gas they are trying to compress is insufficient for the size of the compressor and the blades lose their ability to transfer energy from the shaft to the fluid, causing a reverse...

    Applying Embedded Model Predictive Control

    James Beall 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 widely applied on smaller-scale challenges. At this past 2019 AIChE Spring Meeting , Emerson’s James Beall presented Unique Applications for...
