Maintaining heat-transfer-fluid quality

By Conrad Gamble, Eastman Chemical |

Effective and efficient process operation requires reliable temperature control. This imposes strict demands on the management of the heat-transfer-fluid (HTF) system. This one-page reference provides suggestions for proper maintenance of heat-transfer fluids. Design features necessary to properly maintain acceptable fluid quality can be found in Table 1. Fluid selection A critical parameter of HTF quality is thermal stability, so ensure that the fluid is rated for use up to or above the maximum temperature of operation, keeping in mind the potential for higher-temperature operation in the future. Consider selecting a fluid with excess temperature rating for handling the rigors of stressful service — such as frequent startups (such as in batch processing) where temperature controls may permit high-temperature excursions, or in periods of process upsets — so that the fluid can be more forgiving in times of high stress. Second, consider heat-transfer efficiency at the designed operating temperature. This requires evaluation of the expected relative performance of the fluids for heat transfer coefficients, pumping energy costs and ease of handling (for example, metallurgy and area electrical classification). Third, consider potential…
