  • Understand Heat-Transfer-Fluid Maximum Temperature Rating

    Manufacturers of heat transfer fluids assign a maximum temperature rating to each fluid. This rating must be considered to ensure the safe and efficient operation of the fluid. This paper explains the basis of the rating, how fluids degrade, and how the temperature profile in a heat transfer system affects fluid performance and life.

  • Design the Heat-Transfer-System Expansion Tank Right

    The design of the expansion tank plays an important role in the successful operation of a heat transfer system using organic fluids. It can contribute to longer fluid life and lower maintenance. This paper describes the proper sizing, piping and valving, instrumenting, and inerting of the tank.

  • Maximize Returns from Precious-Metal-Bearing Catalysts

    Many catalytic reactions rely on platinum, palladium and other precious metal catalysts. When the activity of the catalyst declines to the point that it must be replaced, the used catalyst can be sent to a refiner to recover precious metal. This 8-page paper discusses the variouis factors that should be considered when using a refiner.

  • Why Process Safety Management Audits Fail

    Most companies have completed at least three process safety management(PSM) compliance audits of their covered facilities since the promulgation of the OSHA PSM standard. These companies, however, are not seeing noticeable improvements in their PSM programs. In fact, many companies feel that their PSM programs have become less effective. What has happened and why? Are there any lessons learned from the Enron collapse and its auditing program? What needs to be done?

  • Layered Security in Plant Control Environments

    Process control vendors are migrating plant control technologies to more open network and operating environments. This White Paper explains how layered security can be accomplished by adopting a "best practices" model, developing and implementing an access control plan, and compartmentalizing the network.

  • Succeed at Alarm Management

    Today's control system make it easy to add alarms. The result has been a proliferation of alarms that can overwhelm an operator and actually obscure situations that really require immediate attention. This paper provides practical guidance on effective procedures that can significantly reduce nuisance alarms and improve operator effectiveness.
