Therminol 66

transformer-oil

Therminol 66 is a high-temperature heat transfer fluid manufactured by Eastman Chemical Company, primarily used for industrial applications requiring efficient heat transfer at elevated temperatures. It is part of Eastman's Therminol line of synthetic heat transfer fluids, which are widely used in industries such as chemical processing, solar energy, and power generation.

Key Properties

  • High-Temperature Stability: Therminol 66 can be used at temperatures up to 315°C (599°F) in continuous operation.
  • Low Viscosity at High Temperatures: At elevated temperatures, Therminol 66 remains relatively low in viscosity, which helps to reduce the pumping energy required for circulation and minimizes pressure losses in heat transfer systems.
  • Thermal Stability: Therminol 66 is specifically designed to resist thermal degradation, even at high temperatures. This ensures a long operational life without the need for frequent fluid replacement.
  • Oxidation Resistance: It is formulated to resist oxidation, which extends the life of the fluid and helps protect the system against the formation of corrosive acids or other harmful byproducts.
  • Good Heat Transfer Efficiency: Therminol 66 provides efficient heat transfer, helping to ensure optimal system performance and energy efficiency in industrial processes.

Applications

  • Concentrated Solar Power: Therminol 66 is widely used in solar thermal power plants, particularly in systems such as parabolic troughs, where it serves as the heat transfer fluid to transport thermal energy from the solar collectors to the power generation unit.
  • Chemical Processing : In chemical manufacturing, Therminol 66 is used to heat reactors, distillation columns, evaporators, and other high-temperature equipment, allowing for precise control of temperatures necessary for specific chemical reactions.
  • Petrochemical and Refining : It is often used for heating crude oil, lubricants, and other substances in petrochemical refining processes where precise temperature control is needed to optimize production yields and efficiency.
  • Plastics and Polymers : In plastic and polymer production, Therminol 66 is used to maintain precise temperature control in polymerization reactors and extrusion processes.
