Abstract
A product-lubricated multiphase pump for pumping a multiphase mixture containing hydrocarbon includes a separation system and a supply system. To achieve a good cooling and lubrication of pump elements without a lot of operating media and operating medium circuits, the separation system has a first separation stage for at least partly separating at least a portion of the multiphase mixture into a plurality of phase-enriched components and the supply system supplies a liquid-enriched liquid component as lubricant to a pump element to be lubricated.
Claims15
A multiphase pump for pumping a multiphase mixture containing hydrocarbon, comprising:
- a separation system having a first separation stage configured to at least partly separate at least one portion of the multiphase mixture into a plurality of phase-enriched components;
- and
- a supply system configured to supply a liquid-enriched liquid component as a lubricant to a pump element to be lubricated.
A method of operating a multiphase pump, comprising:
- pumping a multiphase mixture containing hydrocarbon, a portion of the multiphase mixture being supplied to a first separation stage of a separation system of the multiphase pump;
- and
- separating, using the separation system, the separated portion into at least one liquid-enriched liquid component and one gas-enriched gas component and the liquid-enriched liquid component being used at least for lubricating a pump element.
