  • 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.

  • 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.

  • 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.
