| Abstract: | The necessity of existing line retrofit is analyzed.Evaluation factors of retrofit solution are expounded.Comparative selection is conducted among three solutions that are gradual replacement of single system,compatible co-existence of new/old equipment and all equipment replacement.Based on the retrofit requirements of different lines,the matching relationship between different retrofit solutions and retrofit requirements are drawn to acquire the most adaptable retrofit solutions targeting different retrofit requirements. |
