My personal physician looks at me like I am a distillation column. Dr. Dianne English worked as a chemical engineer for about five years before attending and completing medical school. As an engineer, she worked for Champlin and Conoco-Phillips — and visited some of the same processing units that I did early during my career. Our conversations are in a language that chemical engineers only half...

Where do middle boilers go? If you answered, “Nobody knows”, then you’re wrong. FRI’s Design Practices Committee (DPC) knows — and they’re willing to share. The DPC was formed in 1975. It originally contained just six members. Neil Yeoman was one of the original members. He still participates on the DPC today — as a consultant. Dan Summers, of Sulzer Chemtech, is...

A variety of performance problems can arise in distillation towers during startup. Many are caused by equipment, hardware or process conditions. Hardware issues may be related to instrumentation, tower internals or ancillaries. Instrumentation malfunctions are also common during startup and are predominantly related to liquid level indicators, online analysis of key components and in some cases...

Every five years or so, a call would come in and once again I would be troubleshooting a certain extraction unit in Canada — usually in the dead of winter. This particular unit had a liquid-liquid extractor, a stripper, a vacuum regenerator and the usual complement of pumps, pipes, valves, vessels, heat exchangers, raccoons and crows. Some of you might remember the extractor from my Crow’s Nest...

The approaches currently used by process integration specialists to assess the opportunities for the integration of reboilers are frequently erroneous and lead to proposals that have to be rejected at the detailed engineering stages or worse, to commissioned reboilers that do not perform properly. This article examines the integration of both vertical and horizontal thermosiphon reboilers, and covers the...

I will bet that many readers are familiar with a Teddy Roosevelt quote that includes the following: “It is not the critic who counts…the credit belongs to the man who is actually in the arena...” Ralph Weiland has been in the arena for many years, doing chemical engineering work that has benefitted many people. At the Spring AIChE meeting this month (Houston; April 1–5), the...
