As environmental regulations and market demands for lower sulfur content in petrochemical products become increasingly stringent, the removal of sulfides in the petroleum chemical industry, particularly those organic sulfides that are difficult to remove, has become a focus of attention for various petrochemical companies and researchers. This paper provides a review of the research progress in organic sulfur compound removal methods over recent years, introducing techniques such as hydroconversion, biological removal, ultrasonic desulfurization, zeolite desulfurization, liquid-phase adsorption desulfurization, and ionic liquid desulfurization, while also outlining the future prospects for the development of organic sulfur removal technologies. Ultrasonic desulfurization involves mixing the feedstock with a small amount of oxidant and a catalyst solution, and using ultrasonic radiation to supply energy that converts the sulfides in the feedstock into sulfates or sulfones that can be easily removed by solvent extraction. Ultrasonic waves are composed of a series of longitudinal waves that alternate in density, and they propagate in all directions through a medium. When ultrasonic waves of a certain intensity travel through a medium, a range of effects such as mechanical, thermal, optical, electrical, and chemical effects occur. Ultrasonic waves can provide the energy needed for the desulfurization reaction and accelerate the chemical reactions involved in desulfurization through other physical effects. When ultrasonic waves act on a material, they can be attributed to the following three basic effects: 1. Mechanical effect – Ultrasonic waves are a form of mechanical energy transmission; they are related to wave phenomena and cause linearly alternating vibrations. When ultrasound propagates through a medium, although the displacement amplitude of the particles is very small, the acceleration of these particles caused by the ultrasound is large; compared to traditional mechanical stirring methods, this allows for more thorough disturbance. 2. Cavitation: As ultrasonic waves propagate through a medium, they can create localized temporary negative pressures in that area, resulting in the formation of tiny bubbles. When these bubbles contract rapidly due to the negative pressure, intense shock waves and jets are generated within the medium; simultaneously, free radicals such as OH- are also produced in aqueous solutions. This provides an extremely suitable physical and chemical environment for the desulfurization reaction. 3. Thermal energy effect ； As ultrasound propagates through a medium, its vibrational energy is continuously absorbed by the medium and converted into heat, causing the temperature inside the medium to rise rapidly. Raising the temperature of the reaction carrier is also beneficial for the entire desulfurization reaction. 　 Based on the aforementioned properties of ultrasonic waves, applying ultrasonic technology to the wet flue gas desulfurization process can effectively accelerate the desulfurization reaction, thereby improving the efficiency of desulfurization.
