Optimizing the Flash Point of Tire-Derived Pyrolysis Oil

September 24, 2025
The flash point of tire-derived pyrolysis oil is a critical quality parameter influencing storage, transportation, and end-use safety. A low flash point increases volatility, leading to flammability risks and limiting the oil’s acceptance in industrial markets. Optimizing this property requires a comprehensive approach that spans feedstock preparation, thermal process design, and downstream refining. Influence of Feedstock and Preprocessing The nature of scrap tire feedstock significantly determines the oil’s volatile fraction composition. Tires with higher proportions of synthetic rubber and additives often generate light hydrocarbons that depress flash point. Preprocessing measures such as shredding and controlled drying help ensure consistent thermal decomposition, while selective removal of non-rubber components minimizes impurities that destabilize oil quality. Uniform feedstock preparation forms the foundation for stable tyre pyrolysis plant outputs.

Transforming Oil Waste Management with TDU

By Cathy Wang • September 9, 2025
The body content of your post goes here. To edit this teThe global oil industry faces growing challenges regarding the management and disposal of waste products, particularly oil sludge. As oil extraction and refining processes produce significant quantities of sludge, the demand for effective waste treatment methods has intensified. Traditional disposal methods such as landfilling or incineration are not only environmentally taxing but are also increasingly regulated by stricter laws. In response, thermal desorption units (TDU) have emerged as a revolutionary solution in the field of oil waste treatment, particularly for managing oil sludge. This innovative technology promises to disrupt conventional waste disposal practices in the oil industry, offering a more sustainable and efficient approach. What is Thermal Desorption Technology? Thermal desorption is a process that uses heat to separate contaminants from solid or semi-solid materials, such as oil sludge. In the context of oil waste management, TDU unit works by applying high temperatures to the contaminated sludge, causing the volatile components, primarily the oil and water, to vaporize. These vapors are then collected and condensed into reusable products, such as oil and clean water. The remaining solid residue, which contains fewer contaminants, can be safely disposed of or further processed. Unlike traditional treatment methods, thermal desorption does not involve combustion, making it a more energy-efficient and environmentally friendly option. This distinction is particularly significant, as traditional incineration and landfilling methods generate harmful emissions and contribute to soil and water contamination. By contrast, TDUs capture the vapors released during the heating process, ensuring that hazardous substances are contained and preventing environmental harm.xt, click on it and delete this default text and start typing your own or paste your own from a different source.
