Composition, performance, and service life

The main difference between synthetic thermal oil and mineral thermal oil lies in their composition, performance, and service life.

Mineral thermal oil is an organic compound produced from high-quality crude oil through processes such as catalytic cracking, atmospheric distillation, vacuum distillation, dewaxing, and refining. Its composition includes various compounds, and the production process is relatively simple and inexpensive. However, mineral thermal oil is prone to producing gel like substances and carbon deposits in high temperature environments, and its usage temperature is limited, usually not exceeding 280 degrees Celsius. In contrast, synthetic heat transfer oil belongs to the alkylbenzene aromatic hydrocarbon type, with lower vapor pressure, no gasification under normal operation, neat molecular structure arrangement, good stability, and longer carbon deposition time. The use temperature range of synthetic thermal oil is wide, with low temperatures reaching over minus 100 degrees Celsius and high temperatures reaching up to 400 degrees Celsius. ‌

In terms of performance, synthetic thermal oil has good thermal stability, strong antioxidant capacity, long service life, and relatively low overall cost. Mineral thermal oil performs poorly in these aspects, has a short service life, and requires frequent replacement. In addition, synthetic thermal oil also has excellent environmental performance, with minimal impact on the environment and easy disposal of waste oil, thereby reducing environmental pressure. ‌

In summary, synthetic thermal oil is superior to mineral thermal oil in terms of composition, performance, and service life. Therefore, synthetic thermal oil will gradually replace mineral thermal oil and become a more preferred heat transfer medium. ‌
