Proper correction of water and heavy hydrocarbon dew points of sweet natural gases is essential from various technical and economical standpoints. Supersonic separators (3S) are proved to be capable of achieving these tasks with maximum reliability...

remarkably if any available relationships between dew point and minimum temperatures and also

long–term average wind speed for each station are exploited. Finally, the minimum data requirements

necessary for adequate performance of the P − M equation...
