Title:
RECTIFICATION CONTROL SYSTEM AND CONTROL METHOD FOR PREPARATION OF ELECTRONIC-GRADE DIFLUOROMETHANE
Document Type and Number:
WIPO Patent Application WO/2023/206724
Kind Code:
A1
Abstract:
A rectification control system (200) and control method for the preparation of electronic-grade difluoromethane. The rectification control system (200) for the preparation of electronic-grade difluoromethane comprises a reactor (210), a reflux tower (220), a degassing tower (230), a rectification tower (240) and a controller (250). An artificial-intelligence-based parameter control algorithm is deployed in the controller (250), so as to dynamically adjust rectification control parameters of the rectification tower (240) on the basis of the overall situation of the rectification control system (200). In this way, the purification precision of electronic-grade difluoromethane is improved from the perspective of optimized control.
