AI Technical Summary
In current chemical production processes, continuous reactions cannot monitor intermediate product indicators and reaction progress in real time, resulting in data lag and the inability to detect anomalies in a timely manner.
The system combines an online near-infrared spectrometer with a distributed control system to monitor the quality of intermediate products in real time. The distributed control system transmits data remotely to trigger alarms and detect anomalies in a timely manner. The system includes a combination design of feed pipeline, reaction vessel, overflow pipeline, stratification tank, balance pipeline, aqueous phase receiving tank, oil phase overflow pipeline, and post-treatment vessel.
It enables online quality inspection of intermediate products without the need for manual sampling, ensuring continuous production, timely detection of abnormalities, and reduction of losses and safety hazards.
