Design provides improved reliability in a polymer-precursor batch reactor. Sensors must respond quickly and survive a harsh environment. Poor probe reliability can make the difference between a process that makes money and one that doesnt.
Quest for more reliable readings prompts development of tougher and more-intelligent sensors. While pH control often plays a crucial role in processing, achieving reliable readings remains challenging at many sites. After all, pH sensors frequently serve in aggressive chemical environments.
High throughput methods are boosting productivity. A survey of member companies by the American Chemical Council (ACC), Arlington, Va., showed that this year the U.S. chemical industry would be spending around 3% more on research and development than it did in 2005.
Outsourcing of non-core operations within a company, large or small, is now a well established corporate strategy. By entrusting services such as IT support, accounting, human resources and other back office activities to specialist firms prepared to do the job at an acceptable price, chemical companies can concentrate on their main business where they are the specialists. That's the theory, at least.
A recent poll provides an industrial perspective and points up its troubling implications. As many universities are discovering, science and technology arent as popular as they once were. It's your job to spread the word, however small.

The proper hand protection plays a tremendous role in keeping plant workers safe. This article answers questions often posed by workers and managers about hand protection products, their applications and limitations.
Changes in liquid densities can throw off readings. Plants commonly rely on differential pressure (DP) cells to measure level. Read this month's Plant InSites for advice on how to solve these level problems.
There's a myth in plants that HART offers little for Plant Control Systems and Enterprise Level Networks. But Ed Ladd from the HART Communication Foundation writes that by accessing the data in HART devices on a "full-time" routine basis increases performance, integrity, and reliability of plant control and enterprise level systems.
