Organic heat transfer medium has low vapor pressure and high boiling point, and has the characteristics of uniform heating, accurate temperature control, and convenient high-temperature operation and transportation. It is widely used in various industries such as chemical industry, printing and dyeing, rubber, resin, coating, road construction, and papermaking. Its uses and usage are increasing. However, due to its use under high temperature conditions, its quality will decline after a period of use, which will greatly limit its service life. It is expensive to replace new heat transfer oil, so regenerating heat transfer oil is of great practical significance for manufacturers to reduce production costs, save energy, and protect the environment.
[0003] The organic heat carrier recovery in the prior art mainly involves chemically treating unqualified heat transfer oil with acid and alkali to adjust the pH value, washing it with water, adding activated carbon or clay for adsorption, filtering, drying, and then collecting the fraction within a certain temperature range through vacuum distillation to achieve the purpose of recovery. This recovery method has a long operation process, requires multiple water washing processes, and will produce salts after acid-base neutralization, decolorizing agents, and clay residues, which pollute the environment. In addition, due to the high boiling point of heat transfer oil, the distillation method consumes a lot of energy and the product yield is low. In addition, due to the large differences in the indicators of different types of heat transfer oil, the waste heat transfer oil has different sources, and the above recovery method may also cause unstable product quality.
[0004] Therefore, in view of the physical and chemical properties of organic heat carriers and the current status of their application and recycling, it is very necessary to design an organic heat carrier boiling point improver and its preparation method which can effectively improve the boiling point of heat transfer oil, improve the quality of heat transfer oil, realize online improvement of heat transfer oil in heat transfer oil circulation system, improve production efficiency and reduce environmental pollution.
