Back To Basics
Mary Ellen Ternes
A basic understanding of environmental law is beneficial for all chemical engineers. Learn how laws are proposed, made, and implemented, and ways to avoid incurring unnecessary penalties.

CEP: Patent Update - An Invention's Nonobviousness May Not Be Obvious

April
2013
Patent Update
M. Henry Heines
To qualify for a patent, an invention must be both novel and nonobvious. Novelty requires that the invention differ in some way from the prior art, such as earlier patents and published materials. Nonobviousness requires that there be more than just...

Reactions and Separations
Stanislaw K. Wasylkiewicz
A tool called azeotrope pressure sensitivity analysis (APSA) can shed light on the dependence of an azeotrope's composition and temperature on changes in pressure.

Realistically Predict Capacity and Pressure Drop for Packed Columns

July
2007
Reactions and Separations
Emil Abkar, Henry Z. Kister, Jeffrey Scherffius, Khashayar Afshar
Generalized pressure-drop correlation (GPDC) charts have been the standard for predicting packing flood points and pressure drops. This article guides engineers on the correct and incorrect uses of the GPDC interpolation procedure, and updates the...
