  • A Dynamic Duo

    Digital valve controllers linked to asset management systems offer a double-barreled approach to valve maintenance.

  • Build reliability in during design

    Instrumentation that promises to improve reliability may not always be what they seem. You have to consider whether a site can properly maintain sophisticated instruments.

  • Faking It Isn’t All Bad

    Simulate or model your loop tuning, operator training, advanced process control or optimization for savings, safety and skill-building.

  • PAT isn’t standing pat

    Traditional laboratory-based analytical techniques more and more are moving online and even being replaced by the virtual analysis offered by soft sensors and inferential measurements.

  • Flame Modeling Provides Matchless Results

    A computer simulation helps solve a refinery combustion problem. Finding ways to limit NOx from fired heaters, especially under stringent environmental regulations, has become a major concern for the petroleum refining industry. Complying with new stricter regulations, a Texas refinery upgraded the burners in one of its large cylindrical furnaces.
