Web25. Sept. 2024 · The so called Flow Induced Pulsations (FLIP) phenomenon occurs in dry gas risers (such as Gas Export lines) and may generate high tonal noises up to 110 dB but may also lead to high vibration of adjacent equipment leading to significant fatigue failure. WebFlow velocities are dependent of the friction factor that is dependent on the construction data of each air lift and therefore no general relation can be derived. The riser velocity values found are in the range of 0.1 up to more than 1 m s −1 for pilot plant (10 l) up to commercial scale (> 1000 m 3) reactors [14].
