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...
Part 1 in the series addressed basic distillation column control and Part 2 explored inferential composition measurement and control design. In today's post I share how we need to consider how to close the material balance and the application of advanced process...
I heard a great story about a resins manufacturer who was having some issues in meeting quality specifications due to temperature variability in the process. Emerson's Gergo Kertesz, whom you may recall from an Emerson Exchange presentation I liveblogged, shared this...
So asks Emerson's Lou Heavner in a thought-provoking post in the DeltaV track of the Emerson Exchange 365 community. Lou opens: Is it good enough? Is it too good? Do you even know? Should you care?Well yes, you probably should care. Most level processes are...
If you're not in the oil refining business the names of the process units, such as cat crackers, can sound quite exotic. Emerson's Tim Olsen, a consultant on the refining industry team, wrote a great AIChE Chemical Engineering Progress article, An Oil Refinery...
Last week, Emerson Consultant James Beall was working with a major U.S. plastics facility on the Texas Gulf Coast, helping the firm figure out how it might save some of the money it spends on distillation energy by using Emerson's Smart Process Distillation Column...
Sometimes when you read an article about tuning proportional-integral-derivative (PID) loops, you're treated to all the 2nd order differential equations they contain. These can be intimidating, especially if your college calculus classes are many years in the rearview...
I've highlighted a few Emerson presentations for this week's ChemInnovations conference in New Orleans. Emerson's James Beall, a 30-year veteran in process control and chairman of the ISA 75.25 committee on control valve performance testing, shared his ChemInnovations...
The distillation process is one of the most common means of separating two or more components from a fluid. Ever handy Wikipedia defines it: Distillation is a method of separating mixtures based on differences in volatilities of components in a boiling liquid mixture....
Process manufacturers across many world areas continually look for ways to improve energy usage, operational efficiency, and quality with the limited resources they have to execute these improvement projects. In a recent Hydrocarbon Processing magazine article,...
A ScienceDirect.com abstract highlights the importance of heat exchangers in refinery energy-efficiency efforts: Crude oil fouling in pre-heat train heat exchangers has been a major problem in oil refining for decades. The operating problems, increased energy...
