Moving from the theoretical world of proportional-integral-derivative control to applying it successfully is a hurdle new process control engineers face. Once mastered, the next step might be in applying advanced process controls. Model predictive control, neural networks, fuzzy logic, gain scheduling and more each require bandwidth and experience to master. One great way to climb […]
Author: James Gremillion One of the earliest applications of “computer control”, a now archaic term, on an ammonia plant was done in 1969 by Weissenfelder and Shah of Borden Chemical and IBM respectively. They were able to implement advanced control schemes in a computer that had proven to be too difficult to do in the […]
Recently, we highlighted a recorded webinar on the use of online analyzers in refinery blending operations. The presenters, Emerson’s Patrick Truesdale and Topnir Systems‘ Didier Lambert, also recently wrote a Processing Shale Feedstocks article, Three steps to successful processing of shale and other opportunity feedstocks. In the article, they highlight the challenge many refiners face […]
I wanted to bring additional visibility to a great thread in the LinkedIn Process Control group on advanced regulatory control versus advanced process control. The post, So, ARC Can “Replace” APC? is based on a blog post, Advanced regulatory versus model-predictive control. The LinkedIn post’s author draws two points from the blog post: ARC is […]
A refinery produces many products, one of them petroleum coke. AFPM defines it: Petroleum coke (petcoke) is one of many valued consumer products produced during the oil refining process. Crude oil is processed into gasoline, diesel fuel, jet fuel, lubricating oils and waxes, leaving some residual crude that usually undergoes additional processing. The crude residue […]
