CEP: November 2015

Liquid-liquid extraction is an important separation technology for a wide range of applications in the chemical process industries (CPI). This month's cover article on liquid-liquid extraction discusses the basics and provides guidance on how to select the appropriate solvent and extraction equipment. Other topics in this issue include toxicology, patents: recognizing novelty, and Malaysia's chemicals industries.


What’s On Your Desk?
Researchers at Cornell Univ. photographed more than 200 kitchens in Syracuse, NY, to determine whether the food sitting out on counters could predict the weight of the woman living in each home. They found that women who had breakfast cereal sitting on their counters weighed 20 lb more than their neighbors who didn’t, and those with soft drinks sitting out weighed 24–26 lb more; women who kept a fruit bowl on the counter weighed about 13 lb less than their neighbors.

Design Principles for Liquid-Liquid Extraction

Reactions and Separations
Joerg Koch, Glenn Shiveler
Many factors must be evaluated when developing a liquid-liquid extraction process. Here are some of the important parameters to consider as you go from laboratory testing to commercial-scale operation.

Toxicology 101

Back To Basics
Christin Grabinski
Every substance can be toxic, depending on the dose and frequency of exposure. This article outlines the basics of toxicology and explores where the research in this field is heading.

Patents: Crossing the Novelty Threshold

Career Catalyst
Henry Heines
Only inventions that are novel qualify for patent protection. Sometimes the novelty of an idea is not readily apparent. Understand where novelty lies so you can identify patentable ideas in your routine engineering work.

The Malaysian Chemicals Industry: From Commodities to Manufacturing

Global Outlook
Dominic C. Y. Foo
A wealth of natural resources is an advantage for Malaysia’s chemicals industry. Since it became independent in the mid-20th century, the country has evolved from a commodities-based economy into a technology and engineering hub
