  • What is taking so long?

    Despite its 30-plus-year history, advanced process control (APC) applications remain few and far between, but it doesn’t need to be that way. Dave Harrold, cofounder of the AFAB Group, reports.

  • Foundation fieldbus in hazardous areas

    Implementing Foundation fieldbus can seem like a daunting task, and when coupled with hazardous-area considerations, may approach information overload; however, it doesn't have to be an explosive concept.

  • Control valves for slurry service

    In this installment of Ask The Experts, noted process control authority and CONTROL Columnist Béla Lipták and his cadre of automation experts answer a reader’s question regarding control valves for slurry services.

  • Defeat barriers to energy cost control

    Use communications and incentives to overcome “The Competitor Within", advises Christopher Russell in this month's Energy Saver column.

  • Achieve continuous safety improvement

    Enhancing safety performance requires diligence and unrelenting effort. The Independent Safety Review Panel’s recently released report on the safety culture and practices at BP’s U.S. refineries where a March 2005 explosion occurred in Texas City, Texas indicates similar failings are likely elsewhere in the industry. Learn what can be done to enhance continuous safety improvement.

  • Pressure control optimization

    Floating pressure control means that, at minimum pressure, the heat required at the reboiler is minimized, its capacity is increased, and fouling is reduced.

  • Take the pressure off pressure control

    Linkage of other variables can stymie hot vapor bypass schemes, according to Andrew Sloley's Plant InSites column.

  • The intrinsically safe fieldbus has arrived

    Fieldbus has proven its merit in bringing projects online more efficiently, allowing better diagnostics, and control, and reducing maintenance costs and inventories. However, it has been limited in intrinsically safe services. At last, technology has come through once again with a solution. The capacity barrier of FISCO has now been significantly surpassed by a novel split architecture design that has already proven itself in the field.

  • Debunk plant myths about diagnostics

    Your current control system can probably do more than you think. Everybody can agree that diagnostics are a good thing — they can identify problems early, and keep the plant running at peak performance. Learn how your existing control systems and analog instruments can deliver diagnostic capabilities, at a fraction of the cost of system or instrument replacements.

  • 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.
