  • 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.

  • Process engineering: Dryer provides a concrete lesson in control

    Removing water or moisture from a liquid stream is a critical operation in many processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves has become much more common.
