  • What Works: Wireless PCs streamline warehouse operations

    The basic principles of Lean Manufacturing date back at least to the 18th century. In Poor Richard's Almanack, Benjamin Franklin wrote, “He that idly loses 5s. [shillings] worth of time, loses 5s., and might as prudently throw 5s. into the river. He that loses 5s not only loses that sum, but all the other advantages that might be made by turning it in dealing, which, by the time a young man becomes old, amounts to a comfortable bag of money.”

  • Gamma scanning seeks an inside edge

    Many companies decide not to build up certain capabilities in-house mainly because they don’t have sufficient regular demand for them. Gamma scanning of distillation columns is a case in point, but on-site scanning specialists may be the wave of the future.

  • Combat contamination

    Consider the impact of slope, fittings and valves. Plants can lose sizable amounts of money each year because of contamination caused in process lines. Owners and contractors alike can take steps in the design and construction phase to enhance the drainability and cleanability of a system.

  • Get full value from partial stroking

    There are two main drivers for partial stroking of valves in safety systems: the desire to extend manual test intervals to as long as possible; and to reduce the amount of redundant hardware required for higher safety integrity levels. Like most things in life, it all boils down to one thing: trying to save money.

  • 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.

  • Try before you buy

    There is another side to toll processing. It involves the companies that arguably have the best possible know-how and hardware — for the simple reason that they are the equipment manufacturers themselves, offering toll processing services that utilize their own products.
