Title:
CONTROL SYSTEM FOR ETHYLENE VINYL ACETATE COPOLYMERIZATION PROCESS AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/236053
Kind Code:
A1
Abstract:
Disclosed are a system and a method for controlling an ethylene vinyl acetate copolymerization process. The system for controlling an ethylene vinyl acetate copolymerization process according to the present technology may comprise: a database for analysis, for storing analysis data obtained by matching process conditions and actual measurement data about first ethylene vinyl acetate (EVA) prepared according to the process conditions; a VA content estimation unit for estimating the vinyl acetate (VA) content in second EVA by using the analysis data; a molecular weight distribution estimation unit for estimating the molecular weight distribution of the second EVA by using the VA content estimated by the VA content estimation unit and a process factor corresponding to same; and a recovery machine clogging estimation unit for estimating the clogging of a recovery machine by using the VA content estimated by the VA content estimation unit and the molecular weight distribution estimated by the molecular weight distribution estimation unit.
