  • pH sensor stands up to tough conditions

    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 doesn’t.

  • pH measurement faces acid test

    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.

  • R&D takes the fast track

    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 moves up the maintenance ladder

    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.

  • Engineers should talk up the profession

    A recent poll provides an industrial perspective and points up its troubling implications. As many universities are discovering, science and technology aren’t as popular as they once were. It's your job to spread the word, however small.

  • Process Engineering: HART Offers Value in Plant Control Systems

    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.
