Would You Use a Safety PLC for Process Control?
With today’s state-of-the-art digital technology, the sky seems to be the limit for doing everything with one system platform. However, with the exception of a few very specific applications, using a safety PLC (programmable logic controller) for...

Variable frequency drives: An Algorithm for Selecting VFDs for Centrifugal Pumps
This article describes an algorithm that end users can use to develop a program on a personal computer to assess the technical and economic feasibility of installing a variable frequency drive (VFD) on centrifugal pumps. This simple algorithm serves a variety of useful functions....

Simulation Software: Beyond Plant Design
As chemical production shifts to growth regions such as China and India, and moves closer to areas like the Middle East, where there are less expensive sources of feedstocks, North American and European chemical processors are under global pressure to...
