A method for delivering a fluid using a centrifugal pump (11). Machines (1, 6) and/or apparatus (3, 8), which influence the pressure and/or the temperature of the fluid, are disposed upstream of the centrifugal pump (11). At the inlet to the centrifugal pump (11), the fluid is regulated to achieve a
A method for delivering a fluid using a centrifugal pump (11). Machines (1, 6) and/or apparatus (3, 8), which influence the pressure and/or the temperature of the fluid, are disposed upstream of the centrifugal pump (11). At the inlet to the centrifugal pump (11), the fluid is regulated to achieve a specific entry state. According to the invention, the entry state of the fluid is regulated by using the machines (1, 6) or apparatus (3, 8) such that, in the centrifugal pump (11), the fluid only takes on states in which the compressibility factor of the fluid has already reached or exceeded the minimum thereof.

1. A method for the conveyance of a fluid with a centrifugal pump, wherein machines and/or appliances which influence the pressure and/or temperature of the fluid are arranged upstream of the centrifugal pump, and the state of the fluid upon entry into the centrifugal pump is set by the machines and/or appliances such that the fluid in the centrifugal pump assumes only states in which the real gas factor of the fluid has already reached or exceeded the minimum value thereof. 2. The method as claimed in claim 1, wherein the fluid is in a supercritical state upon entry into the centrifugal pump and/or in the centrifugal pump. 3. The method as claimed in claim 1, wherein, in the event of an increase in pressure in the centrifugal pump, the real gas factor of the fluid remains the same or increases. 4. The method as claimed in claim 1, wherein the inlet temperature and/or the inlet pressure of the fluid is measured and transmitted to a control or regulating unit. 5. The method as claimed in claim 4, wherein the control or regulating unit transmits signals to the machines and/or appliances for regulating the state in which the fluid enters the centrifugal pump. 6. The method as claimed in claim 4, wherein the control or regulating unit triggers an alarm when the real gas factor of the fluid upon entry into the centrifugal pump is less than the minimum value thereof. 7. The method as claimed in claim 4, wherein the control or regulating unit switches the method into a safety mode when the real gas factor of the fluid upon entry into the centrifugal pump is less than the minimum value thereof. 8. The method as claimed in claim 1, wherein the state in which the fluid enters the centrifugal pump is set by a machine constructed as a compressor and/or by an appliance constructed as a heat exchanger. 9. The method as claimed in claim 8, wherein the fluid to be conveyed passes through at least one compression stage and/or at least one cooling stage. 10. A method for the sequestration of carbon dioxide, in which carbon dioxide is brought to a pressure and/or temperature suitable for an intended storage location and is conveyed into the storage location, wherein a centrifugal pump pumps the carbon dioxide into the storage location;at least one machine and/or appliance which influences the pressure and/or temperature of the carbon dioxide is arranged upstream of the centrifugal pump; andthe state in which the fluid enters the centrifugal pump is set by the at least one machine and/or appliance such that the fluid in the centrifugal pump assumes only states in which the real gas factor of the fluid has already reached or exceeded its minimum value. 11. The method as claimed in claim 10, wherein the fluid is in a supercritical state upon entry into the centrifugal pump and/or in the centrifugal pump. 12. The method as claimed in claim 10, wherein, in the event of an increase in pressure in the centrifugal pump, the real gas factor of the fluid in the pump remains the same or increases. 13. The method as claimed in claim 10, wherein the inlet temperature and/or the inlet pressure of the fluid is measured and transmitted to a control or regulating unit. 14. The method as claimed in claim 13, wherein the control or regulating unit transmits a signal to the at least one machine and/or appliance for regulating the state in which the fluid enters the centrifugal pump. 15. The method as claimed in claim 13, wherein the control or regulating unit triggers an alarm when the real gas factor of the fluid upon entry into the centrifugal pump is less than the minimum value thereof. 16. The method as claimed in claim 13, wherein the control or regulating unit shuts down the plant when the real gas factor of the fluid upon entry into the centrifugal pump is less than the minimum value thereof. 17. The method as claimed in claim 10, wherein the state of entry of the fluid into the centrifugal pump is regulated by at least one machine constructed as a compressor and/or by at least one appliance constructed as a heat exchanger. 18. The method as claimed in claim 17, wherein the fluid to be conveyed passes through at least one compression stage and/or at least one cooling stage.
