Ultrasonic oxidative desulfurization combines the power of ultrasound with oxidative chemistry to remove sulfur compounds from biofuels. The process involves the use of ultrasonic waves to create cavitation bubbles in the fuel. These bubbles generate extreme local temperatures and pressures, which break down sulfur-containing molecules. Simultaneously, an oxidizing agent, such as hydrogen peroxide or ozone, is introduced to convert sulfur compounds into sulfoxides or sulfones, which can then be easily separated from the fuel. https://www.purepathtech.com/ultrasonic-oxidative-desulfurization-plant-2

Solvent extraction is a critical process in the production of high-quality base oil from waste oil. It involves using selective solvents to separate desirable lubricating oil fractions from impurities such as waxes, asphaltenes, and other contaminants. One of the most crucial factors influencing the efficiency and effectiveness of this process is temperature control. https://www.purepathtech.com/base-oil-solvent-extraction-plant
