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. The next question is, “Why does the user still need […]

Simulations can add value across the lifecycle of a manufacturing or production process—from the upfront design work for the capital project portion of the lifecycle to the ongoing operations and maintenance. In a Processing magazine article, Using Life Cycle Dynamic Simulation to Drive Projects And Performance, Emerson’s Sean Sullivan teamed with a third-party consultant working […]

Cybersecurity Considerations in Safety Instrumented System Architectures

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 […]

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. 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 […]

In the mining industry, hydrocyclones are mineral processing equipment used in slurry pulps to separate coarse and fine particles according to their size and density. From Wikipedia: The mixture [slurry pulp] is injected into the hydrocyclone in such a way as to create the vortex and, depending upon the relative densities of the two phases, […]
