Refining processes utilize a wide range of temperatures, depending on process stream composition, system pressure, use of vacuum distillation equipment, etc. For organic separations at high temperatures > 100°C (> 212°F), it is also important to avoid the consequences of water leakage into the process side of operations. The thermally stable synthetic organic chemistries of Eastman Therminol® heat transfer fluids ensure high reliability and on-stream time for heating of fractionation unit reboilers as well as cooling of overhead condensers where water must be avoided. Additionally, the many energy-intensive operations in refinery units offer opportunities for innovative energy integration.
