| Number | Disturbances | Location |
| 1 | Increasing concentration Parameter: 0.5–0.6 at = 0.5 h | Feed |
| 2 | Increasing concentration Parameter: 0.5–0.51 at = 0.5 h | Feed |
| 3 | Increasing flow rate Parameter: 20–20.1 at = 0.5 h | Feed |
| 4 | Increase valve opening Parameter: 12.5%–18% at = 0.5 h | Feed |
| 5 | Decrease valve opening Parameter: 50%–45% at = 0.5 h | Reflux |
| 6 | Decrease valve opening Parameter: 50%–45% at = 0.5 h | Vapor |
