Compressed Air Best Practices - June 2008 - (Page 13) Focus Industry PHARMACEUTICALS | 06–07/08 | Adiabatic Expansion Through further investigation we found the root of the problem. When air is discharged from the piping between the cylinder and the valve, the temperature of the air drops due to adiabatic expansion. If the atmospheric dew point of the supply air is T1, and the temperature of the air T2 after adiabatic expansion falls below this value (T1<T2), then mist formation occurs. Most of the mist is discharged through evaporation by the surrounding heat. However, a small amount of residual mist tends to adhere to the inner wall of the piping. The solenoid valve is switched again and new compressed air is supplied, so the residual mist in condition remains on the side of the cylinder. The second issue was the length of piping between the cylinder application and the valve. When the cylinder is small and the piping is long (that is, the volume of the piping is longer than that of the cylinder), air inside the cylinder cannot be exhausted at the time of the release and remains inside the piping. As the cylinder cycles, the mist accumulating near the cylinder increases, finally resulting in the formation of large water drops and condensation.
