Collecting tank, system comprising collecting tank and multi-phase pumps, and method for separating and dividing up a multi-phase mixture
The invention relates to a collecting tank for multi-phase mixtures from a hydrocarbon source, having at least one inlet ( 20 ) for introducing multi-phase mixtures into the collecting tank ( 10 ), and having a plurality of outlet connectors ( 30 ), which can be connected to pumps ( 3 ) via which multi-phase mixtures are pumped, the outlet connectors ( 30 ) being assigned inwardly directed internals ( 40 ) which project upwards beyond the collecting-tank base ( 11 ) and have a first, upper opening ( 42 ) and a second, lower opening ( 41 ), wherein the flow cross section of the lower opening ( 41 ) is smaller than that of the upper opening ( 42 ).
1. A collecting container for multi-phase mixtures from a hydrocarbon source, comprising:
at least one inlet for introducing multi-phase mixtures into the collecting container;
a plurality of outlet connectors which are connectable to pumps via which multi-phase mixtures are pumped; and
inwardly directed internals which project upwardly beyond a base of the collecting container and have a first, upper opening and a second, lower opening, wherein the plurality of outlet connectors are each in fluid communication with at least one of the inwardly directed internals,
wherein the inwardly directed internals are mounted displaceably and/or rotatably in the collecting container;
wherein a flow cross section of the lower opening is smaller than that of the upper opening, and
wherein the lower opening is assigned its own adjustable throttle or closure device.
2. The collecting container as claimed in claim 1 , wherein the plurality of outlet connectors are oriented downwardly in an inclined manner or vertically downwardly.
3. The collecting container as claimed in claim 1 , wherein the collecting container is a collecting pipe or collecting tank.
4. The collecting container as claimed in claim 1 , wherein the upper opening in each of the inwardly directed internals is oriented vertically upwardly.
5. The collecting container as claimed in claim 1 , wherein the inwardly directed internals are inserts, pipe sections, baffle plates, or deflector plates.
6. The collecting container as claimed in claim 1 , wherein the inwardly directed internals are assigned adjustment devices, via which a free flow cross section of the upper and/or lower opening in the inwardly directed internals is capable of being varied from outside the collecting container.
7. The collecting container as claimed in claim 1 , wherein the collecting container is formed in a closed manner.
8. The collecting container as claimed in claim 1 , wherein closure or metering devices are arranged on one or more of the following: outlet connectors, outlet pipelines, and the inwardly directed internals.
9. The collecting container as claimed in claim 1 , wherein separation devices are arranged in the collecting container and separate the gas phase from the liquid phase.
10. A system comprising
at least one collecting container comprising:
at least one inlet for introducing multi-phase mixtures into the collecting container;
a plurality of outlet connectors which are connectable to pumps via which multi-phase mixtures are pumped; and
inwardly directed internals which project upwardly beyond a base of the collecting container and have a first, upper opening and a second, lower opening, wherein the plurality of outlet connectors are each in fluid communication with at least one of the inwardly directed internals,
wherein the inwardly directed internals are mounted displaceably and/or rotatably in the collecting container;
wherein a flow cross section of the lower opening is smaller than that of the upper opening, and
wherein the lower opening is assigned its own adjustable throttle or closure device; and
a plurality of multi-phase pumps connected to the at least one collecting container.
11. The system as claimed in claim 10 , wherein the plurality of multi-phase pumps includes at least one inlet multi-phase pump arranged on an inlet side of the at least one collecting container, and further comprising a line that leads from the collecting container to the inlet side of the at least one inlet multi-phase pump.
12. The system as claimed in claim 10 , further comprising a control device which is coupled to sensors and adjustment devices arranged on the plurality of multi-phase pumps and adjusts a flow cross section of at least one opening on the basis of values from the sensors.
