As an excellent heat transfer medium, heat transfer oil furnaces can experience coking or carbon deposition as a result of thermal polymerization, thermal cracking, and thermal oxidation reactions that occur during use. When this buildup reaches a certain level, it significantly impairs the heat transfer efficiency. In particular, hard carbon deposits must be thoroughly cleaned to ensure smooth production processes. Coking and solidification of heat transfer oil generally manifest themselves in various ways such as slow equipment heating, uneven temperature distribution, and reduced heat transfer efficiency; at the same time, the heat transfer oil also ages. If the equipment in a company fails to reach the required temperature, we can analyze various parameters of the heat transfer oil, such as residual carbon, acid value, kinematic viscosity, and flash point, in order to determine whether the heat transfer oil system is contaminated. If these values are significantly above the acceptable limits, it indicates that coking and carbon deposition have occurred on the inner walls of the pipes in the heat transfer oil system. If these deposits are not removed promptly and the system continues to be used, they will accumulate more and become thicker, increasing fuel consumption. In severe cases, this can lead to blockages in the heat transfer oil tubes, eventually rendering the boiler unusable and causing substantial losses for the factory. It is difficult to clean thermal oil once it has solidified; ordinary water-based products are basically ineffective, while solvent-based products work well but are somewhat expensive. They are suitable for use in small heating devices. Among the various cleaning methods for heat transfer oil heating systems, online cleaning is the most effective, environmentally friendly, and scientific approach. It addresses the issues associated with traditional water-based cleaning methods, such as the generation of large amounts of wastewater that pollutes the environment, waste of water resources, complexity in the cleaning process, and the dangers and risks associated with solvent-based cleaners. It completely solves the problem of being unable to clean heat transfer oil systems during production, making it the most scientific and effective method for cleaning such systems. Take SP-3 heat transfer oil online cleaner as an example; the advantage of using it for cleaning is that it enables the heat transfer oil equipment to be cleaned without any downtime. It contains hydrogen-rich polar groups that can form hydrogen bonds with the hydrocarbon chains of the cracked heat transfer oil (through dehydrogenation), thereby fully dissolving the coking substances. These substances are then dispersed within the heat transfer oil system thanks to the dispersant. The cleaner is compatible in polarity with the oil tar sludge, which allows the dirt to be broken up and reintegrated into the heat transfer oil. Its cleaning efficiency is significantly superior to that of water-based and solvent-based cleaners; even hardened carbon deposits can be rapidly dissolved in the shortest possible time, which allows for a quick increase in temperature and ensures good heat exchange performance, thereby adding value to the company’s production processes. There will be no damage to the heat transfer oil during cleaning. The SP-3 online cleaning agent is completely non-flammable, non-explosive, and non-corrosive; it causes no harm to equipment, pipelines, or human health. There is no waste water or waste gas generated after cleaning, ensuring that the entire cleaning process is safe and environmentally friendly.
