| Abstract: |
| The working principles and technological characteristics of freezing water vacuum system and glycol type dry ice condensation vacuum system were introduced, and their technical performances were compared. The economic benefits of two vacuum systems applied in different scale deodorizing production lines were compared, and their applicable ranges were analyzed. The results showed that the freezing water vacuum system was more suitable for medium and small scale oil refining deodorization vacuum systems, and the glycol type dry ice condensation vacuum system was more suitable for large and medium scale oil refining deodorization vacuum systems. |
