Protection of High-Temperature Synthetic Heat Transfer Oil by Jiangxi Tianyi Special Oil During Use

At Jiangxi Tianyi Special Oil, we specialize in the production of high-quality Heat Transfer Fluids such as Dibenzylbenzene (DBT) and Monobenzyltoluene (MBT) formulations, which are known for their exceptional performance as Thermal Conductive Oil in high-temperature applications. Here are some essential measures to protect your high-temperature synthetic heat transfer oil during use:

1. Preventing Oxidation: High-temperature synthetic heat transfer oil, including our DBT and MBT products, is susceptible to oxidation when operating at high temperatures within a heat transfer system, which can lead to deterioration. To prevent this, a high-temperature expansion tank is usually equipped with nitrogen for protection at Jiangxi Tianyi Special Oil, ensuring the closure of the heat transfer system. This prevents contact between the oil and air, thereby extending the service life of the high-temperature heat transfer oil.

2. Preventing Carbon Deposition: When the operating temperature of the high-temperature synthetic heat transfer oil exceeds the maximum allowable temperature, carbon deposition can occur on the inner walls of the heat transfer pipes. As the carbon layer builds up, the temperature of the pipe walls increases, reducing heat transfer performance and potentially leading to explosive hazards. It is crucial to strictly control the temperature of the high-temperature synthetic heat transfer oil at the heat carrier outlet to not exceed the maximum operating temperature, ensuring the maximum film temperature of the heat carrier is lower than the allowable oil film temperature.

3. Regularly Cleaning Leak Points and Monitoring Equipment: At Jiangxi Tianyi Special Oil, we emphasize the importance of strengthening on-site monitoring, ensuring the integrity of the heat transfer system, and regularly inspecting the equipment for corrosion and leaks. Timely repairs should be conducted if any issues are found. The heat transfer system should be designed reasonably, and the wall thickness and pressure strength of the equipment should be regularly inspected during use. Pressure gauges, safety valves, and vent pipes should be installed on the equipment and pipelines.

4. Preventing Water and Other Impurities from Mixing with the Heat Carrier: As the heat carrier is heated, dissolved water rapidly evaporates, causing a sharp increase in pressure within the heat pipes, which can lead to uncontrolled conditions and potential explosions. High-temperature synthetic heat transfer oil, such as our DBT and MBT products, should be heated slowly before use to remove water and other light impurities.

5. Regularly Testing Heat Transfer Oil Indicators: At Jiangxi Tianyi Special Oil, we recommend regularly testing various indicators of high-temperature synthetic heat transfer oil. Periodically determine and analyze the residual carbon, acid value, viscosity, flash point, melting point, and other physical and chemical indicators of the heat carrier to timely grasp its quality and analyze the reasons for any changes. If the acid value exceeds 0.5mgKOH/g, the viscosity change reaches 15%, the flash point change reaches 20%, and the residual carbon (mass fraction) reaches 1.5%, it indicates that the performance of the high-temperature synthetic heat transfer oil has changed. Regularly adding new heat carriers in appropriate amounts helps maintain the basic stability of the residual carbon in the system.
