A conveying device for conveying a liquid/gas mixture, in particular a crude-oil/natural-gas mixture, taken from a borehole, having a multiphase-pumping device, which can be or is coupled to a feed line and a discharge line and to which the liquid/gas mixture can be fed as a feed flow, via the feed line and via which the mixture can be discharged under increased pressure as a conveyance flow, into the discharge line, and having a recirculation line, via which a sub-flow of the liquid contained in the conveyance flow can be returned to the feed flow. The recirculation line contains an injector, through which the sub-flow is conducted, with a negative pressure being generated in the process, and which can be or is coupled to a gas line, which conducts a gas taken from the borehole. The negative pressure causes the gas to be taken in by suction.
A conveying device for conveying a liquid/gas mixture, in particular a crude-oil/natural-gas mixture, taken from a borehole, having a multiphase-pumping device, which can be or is coupled to at least one feed line and a discharge line and to which the liquid/gas mixture can be fed, in the form of a feed flow, via the feed line and via which the mixture can be discharged under increased pressure, in the form of a conveyance flow, into the discharge line, and having a recirculation line, via which a sub-flow of the liquid contained in the conveyance flow can be returned to the feed flow, wherein the recirculation line contains an injector, through which the sub-flow can be conducted, with a negative pressure being generated in the process, and which can be or is coupled to at least one gas line, which conducts a gas, in particular natural gas, taken from the borehole, wherein the negative pressure can cause the gas to be taken in by suction.
A method which is intended for conveying a liquid/gas mixture, in particular a crude-oil/natural-gas mixture, taken from a borehole and in which, by means of a multiphase-pumping device, which is coupled to a feed line and a discharge line, the liquid/gas mixture fed in the form of a feed flow via the feed line is conveyed under increased pressure, in the form of a conveyance flow, into the discharge line, wherein a recirculation line is used to return a sub-flow of the conveyance flow to the feed flow, wherein the sub-flow flows through an injector, which is provided in the recirculation line, this generating a negative pressure which causes a gas conducted in a gas line and taken from the borehole to be taken in by suction.
