Introduction to the physical and chemical properties of heat carrier oil for electric heating reactor

The heating medium in the jacket of an electric-heated reactor is chosen based on the required process temperature. For temperatures above 100°C, heat transfer oil (thermal oil) is typically used, while water is suitable for temperatures below 100°C. Electric-heated reactors must include expansion tanks to accommodate the thermal expansion of the medium during heating.

Heat transfer oil, also known as thermal oil, is widely used in industrial applications due to its ability to provide uniform heating, precise temperature control, and high thermal efficiency. It operates effectively at near-normal pressure, reducing safety risks and system complexity. Additionally, it eliminates the need for water treatment systems, lowering maintenance and operational costs.

When selecting thermal oil, it is crucial to determine the appropriate heating process flow and address any system design or operational issues to prevent coking. Established domestic brands, such as Great Wall and Kunlun, offer cost-effective options, while international brands like Mobil and Castrol provide higher quality.

Thermal oil reactors are used across various industries, including rubber and plastics, fine chemicals, oleochemicals, chemical fiber, papermaking, wood processing, electrical processing, energy, food, air conditioning, construction, and textile industries. Their versatility and efficiency make them essential for processes requiring precise and reliable heating.
