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 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 computer programmed to estimate a VA content with respect to second EVA using the analysis data, a computer programmed 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 computer programmed to estimate a recovery system blockage phenomenon using the VA content estimated and the molecular weight distribution estimated.
