| Abstract: | The transition strategy during the grade transition of polypropylene is analysed. With the dynamic model of propylene polymerization, soft measurement of Melt Index (MI), and the industrial data, the grade transition is simulated on the Hypol Process. The result shows the grade transition could be simulated with the dynamic model of propylene polymerization faithfully. With the result, the optimal grade transition strategy could be found to get remarkable economic benefit. |
