  • Blind Transmitters: A return to the basics

    Analog transmitters easily send process measurements from different areas in a plant to a central PLC where process control decisions can be made based on transmitter feedback. Analog transmitters are great cost-saving alternatives to single-point controllers. In situations where multiple sensing locations are required, single point controllers’ costs can add up quickly.

  • Diagnostics dig deeper

    Today’s plants come ready equipped with their own team of doctors in the shape of the many diagnostic and monitoring systems incorporated into instrumentation and other process equipment. And, like any good doctor, today’s plant diagnostics can look beyond the symptoms of poorly performing instruments and provide insights into the health of the process itself.

  • Plug it in?: The decision to integrate condition monitoring

    Efforts to tighten communications of condition-monitoring instrumentation and data analysis software with CMMS and automation infrastructure, combined with the proliferation of wireless sensor systems and the drive to reduce manpower skill and time requirements, are bringing implementation costs down and drawing much attention to this approach. But should you implement it?

  • What’s in the air for continuous emissions monitoring?

    More attention to mercury and increased acceptance of predictive approaches is emerging. Such monitoring not only can keep plants on the right side of regulators but also can help provide insights for optimizing operation of equipment.

  • 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.
