Core Technology Modules
The system combines multiple process functions into one coordinated industrial solution for sulfur removal, separation, and resource recovery.

01 / Ultrasonic Oxidation Module
Ultrasonic-Enhanced Oxidation Reaction
A high-frequency energy field creates cavitation and localized mass transfer intensification, improving oxidant dispersion and sulfur compound conversion for downstream extraction efficiency.

02 / Extraction Separation Module
Selective Extraction and Phase Separation
After oxidation pretreatment, target compounds are selectively transferred into the extraction phase, enabling deeper sulfur removal and better purification performance.

03 / Recovery and Recycling Module
Solvent Recovery and Closed-Loop Operation
Spent solvents or extractants are regenerated and returned to the process, reducing solvent consumption, lowering waste treatment demand, and improving long-term operating economics.
