———— Process Intelligence
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.
———— Process Intelligence
Process Flow
The process is designed to deliver efficient sulfur removal, stable separation, and solvent recirculation in one integrated workflow.
