Abstract
During the drying of long-distance pipelines, in a development of vacuum drying--possibly in combination with compressed-air drying, go-devils and/or alcohol drying--a flooding is provided which precludes the recondensation of the water in the residual water vapor. For this purpose a movement of drawn-off water vapor and following scavenging gas in the same direction is ensured and the scavenging gas is throttled in its input of travelling speed so that no condensation occurs even in the boundary region to the departing water vapor.
