Title:
エチレンビニルアセテート共重合工程の制御システム及びその制御方法
Document Type and Number:
Japanese Patent JP6780091
Kind Code:
B2
Abstract:
Disclosed are a system for controlling an ethylene vinyl acetate (EVA) copolymerization process and a method of controlling the same. The system for controlling the EVA copolymerization process according to the present invention may include a database for analysis configured to store analysis data obtained by matching processing conditions with measured data for first EVAs produced under the processing conditions, a vinyl acetate (VA) content estimation unit configured to estimate a VA content with respect to second EVA using the analysis data, a molecular weight distribution estimation unit configured to estimate a molecular weight distribution of the second EVA using the VA content estimated in the VA content estimation unit and processing factors corresponding thereto, and a recovery system blockage estimation unit configured to estimate a recovery system blockage phenomenon using the VA content estimated in the VA content estimation unit and the molecular weight distribution estimated in the molecular weight distribution estimation unit.
