RECTIFICATION CONTROL SYSTEM AND METHOD FOR PREPARING ELECTRONIC-GRADE CARBON TETRAFLUORIDE

Title:

RECTIFICATION CONTROL SYSTEM AND METHOD FOR PREPARING ELECTRONIC-GRADE CARBON TETRAFLUORIDE

Document Type and Number:

WIPO Patent Application WO/2024/098604

Kind Code:

A1

Abstract:

Disclosed in the present application are a rectification control system and method for preparing electronic-grade carbon tetrafluoride. Deep-learning-based artificial intelligence control technology is used to perform feature extraction on collaborative associated features of temperatures and pressures of different areas of a refining section and a multi-scale change feature of the flow velocity of a flow medium, transfer vectors of the features are further used to represent relevance feature information between the collaborative associated features of temperatures and pressures and a dynamic change feature of the flow velocity of the flow medium, and self-adaptive real-time control over the opening degree of a valve of the flow medium is performed on the basis of the relevance feature information; and spatial topological features of the different areas of the refining section are introduced during this process, so as to further enhance the extraction of the collaborative associated features of temperatures and pressures at spatial positions, thereby improving the precision for controlling the opening degree of the valve of the flow medium. In this way, the rectification efficiency can be improved, and the consumption of the cooling capacity can be reduced.
