Abstract

The present disclosure provides a formation method for a slug flow that includes combining a first liquid and a second liquid that is not compatible with the first liquid, moving the second liquid that is combined with the first liquid to an upstream side with respect to a combination point of the first liquid and the second liquid in a flow direction of the first liquid, and moving, by the first liquid, the second liquid that is retained on the upstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid, to a downstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid, where a density D1 of the first liquid and a density D2 of the second liquid satisfy a relationship of D1>D2, and provides an application thereof.

moving, by the first liquid, the second liquid, which is retained on the upstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid, to a downstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid; and,
the retaining the second liquid, which has been moved to the upstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid, comprising arranging the first liquid and the second liquid vertically in the direction of gravity;
wherein a density D1 of the first liquid and a density D2 of the second liquid satisfy a relationship of D1>D2.

2. The formation method for a slug flow according to claim 1 ,
wherein at the combination point of the first liquid and the second liquid, an angle Θ1 between the flow direction of the first liquid that is combined with the second liquid and the direction of gravity and an angle Θ2 between a flow direction of the second liquid that is combined with the first liquid and the direction of gravity satisfy a relationship of Θ1<Θ6.

3. The formation method for a slug flow according to claim 1 ,
wherein at the combination point of the first liquid and the second liquid, an angle Θ1 between the flow direction of the first liquid that is combined with the second liquid and a direction of gravity is 0° or more and less than 90°.

4. The formation method for a slug flow according to claim 1 ,
wherein the density D1 of the first liquid and the density D2 of the second liquid satisfy a relationship of 5 kg/m 3 <=D1−D2.

5. The formation method for a slug flow according to claim 1 ,
wherein a flow rate R1 of the first liquid and a flow rate R2 of the second liquid satisfy a relationship of R1>R2 or a relationship of R1<R2.

6. The formation method for a slug flow according to claim 1 , further comprising combining the first liquid and the second liquid at a combination part of a device having;

a second pipe line through which the second liquid flows,
the combination part at which the first pipe line and the second pipe line communicate with each other and the first liquid and the second liquid are combined, and
a third pipe line which is connected to the combination part and through which the combined first liquid and second liquid flow.

7. The formation method for a slug flow according to claim 6 , further comprising retaining the second liquid at a retention part that is located inside the first pipe line and retains the second liquid that has been moved to the upstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid.

8. The formation method for a slug flow according to claim 7 ,
wherein the retention part is a reduced diameter part of which an inner diameter is reduced from the downstream side toward the upstream side in the flow direction of the first liquid.

9. The formation method for a slug flow according to claim 7 ,
wherein the retention part is a reduced diameter part of which an inner diameter is reduced from the downstream side toward the upstream side in the flow direction of the first liquid and which is configured to adjust a distance L1 from a center of the combination part to the retention part.

10. The formation method for a slug flow according to claim 7 ,
wherein the retention part is an end part of a pipe line that is inserted into the first pipe line on the upstream side with respect to the combination point of the first liquid and the second liquid in the flow direction of the first liquid and has an inner diameter smaller than an inner diameter of the first pipe line.

11. The formation method for a slug flow according to claim 7 ,
wherein the retention part is a mesh-shaped member.

12. The formation method for a slug flow according to claim 7 ,
