| Abstract: | The amount of additives was optimized for polyester production by esterification on a continuous polymerization unit imported from Teijin Company, Japan. The experimental reduction of cobalt acetate, titanium dioxide, zine acetate and stabilizer was conducted seperately on a commercial plant. The results showed that when the amount of cobalt acetate, zine acetate and stabilizer was decreased by 50% and the amount of titanium dioxide was decreased to 0 29% from 0 35%, the product quality was improved with the reduced production cost. |
