Title:
RECTIFICATION CONTROL SYSTEM AND RECTIFICATION CONTROL METHOD FOR PREPARING ELECTRONIC-GRADE METHYL FLUORIDE
Document Type and Number:
WIPO Patent Application WO/2023/206914
Kind Code:
A1
Abstract:
The present application relates to the field of intelligent manufacturing of an electronic-grade gas, and specifically discloses a rectification control system and a rectification control method for preparing electronic-grade methyl fluoride. The rectification control system comprises a pre-mixer, a reactor, a separation column, a water-washing column, an alkaline-washing column, a drying column, a rectification column, and a rectification column control system, wherein the rectification column control system uses an intelligent control method based on artificial intelligence technology to dynamically regulate and control the pressure and temperature of the rectification column so as to optimize the purification precision of the electronic-grade methyl fluoride from a control end.
