Abstract
A process in connection with a pipe () for transforming a dispersed gas/liquid flow into laminar stratified flow. The solution involves a first set of stationary guide blades () arranged in the pipe () and designed to rotate the liquid/gas flow. The pipe () is, in turn, connected to a second pipe () with the same or a different diameter and, in the transition between the pipe () and the second pipe (), there is a second set of blades or a device () that is designed to stop the rotation of the gas. The natural flow pattern of the gas/liquid in the second pipe () then becomes stratified over a predefined distance.
