  • 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.

  • Properly Clean Organic Heat Transfer Fluid Systems

    Maintaining peak performance of organic heat transfer fluids can require removal of dirt and pipe scale, oxidation, thermal degradation, and process contamination. This paper describes the appropriate cleaning techniques for dealing with solids; sludge, high-viscosity fluid and residues; process contamination; and hard coke.
