Distillation columns are often workhorses in the chemical process industries (CPI), and at times, it is necessary to physically inspect the interior of a column. This article demonstrates what an inspection can reveal, by sharing the experience of actual fractionation-tower inspections in a petroleum refinery. The points mentioned are intended to provide guidance to future tower inspectors, so that they...

So I called my son, Steve, and I asked him, “Which course sounds better to you, ‘Dealing with Difficult People’ or ‘Unacceptable Employee Behavior’?” Steve is a human resources specialist at a 2,000-employee company. He is not a member of the AIChE, but is instead a member of the ACHE, the American College of Healthcare Executives. Proof that the apple does not fall far...

A common practice in the chemical process industries (CPI) is to implement so-called value- maximization projects (VMP) to increase production or reduce production costs in order to increase profit margins. With such projects, one main objective of the design team is to incur minimum capital expenditures. Because most VMPs aim to increase throughput or production yield, many such projects involve changes...

When it comes to distillation trays and packing, chemical processors require the same criteria they seek from all equipment in this tight economy — technology that will reduce energy use and boost throughput without costly facility expansion. In an effort to meet these needs, tray and packing specialists are improving existing technologies and launching a whole new generation of trays designed to...

Raise your hand if you ever regretted going with the low cost bidder. Keep your hand raised if the low cost bidder ever yielded you the highest cost result. If your officemate is staring at you quizzically, pretend to be working out the shoulder kink that originated two evenings ago when you played racket ball with the vice president of human resources at the gym. Distillation columns at Fractionation...

It was the Dr. James R. Fair Heritage Distillation Symposium at the Chicago AIChE meeting last month. I had decided to finally give a presentation about something that has been bugging me since October 28, 1974, my first day as a practicing chemical engineer. “Regarding distillation trays, I do not believe in entrainment. I believe that I am at least 50% correct.” I had the audience’s...

Manufacturers of specialty chemicals are routinely required to reduce costs and increase the production of their high-value products. Specifically, competitive pressures from the developing world, increases in raw material costs and volatility in energy costs are putting significant pressure on manufacturers to minimize processing costs and maximize product yields. The economic impact of optimization...
