Problems solved by technology

[0007] Heat transfer oil is mostly used under continuous high temperature conditions, and its operating temperature is generally between 200-400 ° C. If heat transfer oil is operated in a high temperature environment for a long time, thermal cracking, polycondensation and oxidation reactions will occur. As a result of thermal cracking reactions, low boiling point substances will be produced. , leading to lower flash point and lower safety
Low boiling point substances will also undergo polymerization and condensation to form high molecular substances, colloids, etc., resulting in increased viscosity and carbon residue, causing coking, which adheres to the tube wall of the heating furnace, reducing heat transfer efficiency and increasing energy consumption
The oxidation reaction produces organic acid, which increases the acid value of the heat transfer oil. Deep oxidation also produces insoluble acid mud, which increases the viscosity of the heat transfer oil, which eventually shortens the service life of the heat transfer oil and even damages the equipment. Therefore, the heating rate and Service life is especially important
