Stable and precise temperature control is integral to high-quality, high-yield biodiesel production. Reaction vessels must be maintained at specific temperatures to allow transesterification to proceed efficiently to completion. Feedstock pretreatment, biodiesel washing, bleaching, and drying, methanol recovery, glycerol refining, indeed nearly every step of biodiesel production requires efficient heating or cooling of product, from temperatures of 25 deg C or lower to 200 deg C or more in some processes. The choice of heat transfer fluid is therefore vital: when it comes to biodiesel, Therminol® heat transfer fluids ensure the high thermal stability required for optimum yields and product quality.
Therminol heat transfer fluids suitable for biodiesel applications include:
Therminol 55 heat transfer fluid provides reliable, consistent heat transfer performance at low cost over a temperature range required for typical biodiesel processes.
Therminol 59 heat transfer fluid has superior low-temperature pumpability, providing consistent performance for more effective cooling and cold-climate operation while also meeting the heating requirements of most biodiesel operations.
Therminol 66 heat transfer fluid offers legendary thermal stability and a wide operating range which makes it a suitable candidate for the demands of near-supercritical and supercritical processing in biodiesel processes.
Therminol XP heat transfer fluid, already widely used in food oil processing, is thermally stable, is registered with NSF (HT1) in applications where there is a possibility for incidental food contact, and provides Therminol quality in a white mineral oil.
