Process for transforming gas/liquid flow into laminar or stratified flow
View Patent ↗A process in connection with a pipe ( 1 ) for transforming a dispersed gas/liquid flow into laminar stratified flow. The solution involves a first set of stationary guide blades ( 6 ) arranged in the pipe ( 1 ) and designed to rotate the liquid/gas flow. The pipe ( 1 ) is, in turn, connected to a second pipe ( 2 ) with the same or a different diameter and, in the transition between the pipe ( 1 ) and the second pipe ( 2 ), there is a second set of blades or a device ( 8 ) that is designed to stop the rotation of the gas. The natural flow pattern of the gas/liquid in the second pipe ( 2 ) then becomes stratified over a predefined distance.
1. A process for transforming a dispersed liquid/gas flow comprising liquid and gas into a stratified flow, wherein the process comprises:
introducing the liquid/gas flow into a first pipe in which a set of stationary guide blades is arranged and which causes the liquid/gas flow to rotate;
transmitting the liquid/gas flow to a second pipe connected to the first pipe, the second pipe having the same diameter or a different diameter than the first pipe; and
stopping the rotation of the gas in the liquid/gas flow with a mechanism so that the flow pattern of the gas/liquid in the second pipe becomes stratified over a predefined distance and under the influence of a gravitation force, wherein the mechanism is a perforated plate that is located in a transition area between the first and second pipes.
2. A process in accordance with claim 1 , wherein the second pipe has a larger diameter than the first pipe.
3. A process in accordance with claim 1 , wherein a venturi is arranged in the first pipe, and the set of stationary guide blades is arranged at the inlet of the venturi, while the mechanism is arranged at the outlet of the venturi.
4. A process in accordance with claim 1 , wherein the perforated plate is arranged at an angle in relation to the longitudinal direction of the first pipe.
5. A process in accordance with claim 1 , wherein the first and second pipes are disposed in a horizontal orientation.
6. A process in accordance with claim 4 , wherein the angle at which the perforated plate is arranged has a direction that is opposite to a guide direction of the set of stationary guide blades.
7. A process in accordance with claim 1 , wherein the perforated plate is arranged in a vertical direction.
8. A process in accordance with claim 1 , wherein the perforated plate is arranged in a horizontal direction.
