Rotodynamic multiphase pumps are usually equipped with many compression units to provide sufficient boosting pressure for the transportation of production fluid in gas oil field. It is a challenge to maintain pump performance while flow parameters in each stage vary due to the compressibility of gas-liquid phase. In this article, a stage-by-stage design method is proposed to improve the boosting capability of a multiphase pump. Variations of flow parameters in each stage are investigated based on computational fluid dynamics (CFD) numerical simulation. Available methods to determinate main impeller geometry parameters of impeller are discussed. The stage-by-stage design method is applied on a five-stage multiphase pump when the inlet gas volume fraction (GVF) are 30% and 50% separately. The second stage is modified base on its corresponding inlet flow parameters when inlet GVF is 30% while the second and third stage are modified when inlet GVF is 50%. Flow parameters, pressure distribution and velocity distribution are compared between the original pump and modified pump. Differential pressure of the modified pump increases by 53.72 kPa and 58.57 kPa respectively when inlet GVFs are 30% and 50%. The feasibility of the stage-by-stage design method is verified through the comparison results.

Specifying and selecting equipment for gas compression projects is a complex process involving many engineering disciplines. All the alternatives and the possible interaction between the various components in the system should be carefully examined by the project team. The accumulation of errors in evaluating the system characteristics during the project engineering phase, can lead to the gas compression system not performing to design specifications. This paper describes the problems encountered with the compressor package during the commissioning of four gas turbine-driven compressor stations for gas lift in one of the onshore oilfields in the Middle East. Solutions to these problems are also outlined.

Abstract This paper describes Kvaerner’s prototype subsea multiphase pump system and the DEMO 2000 development program (current test completion date 2nd Q2001). Reference is also made to service proven sub-systems, components and subsea expertise incorporated into the pump module and system design. Availability and reliability consideration together with novel plans for the future is presented. The Subsea Multiphase Pump and motor are packaged into a modular system solution that is readily adaptable to template and manifold configurations and maximises the use of existing qualified components and sub-systems. A guidewireless system is adopted and Kvaerner’s design ensures self-alignment upon installation at simple flowbase interfaces, making it ideal for deepwater applications. Due to the individual 40 tonne weight, and moonpool dimensions, of both flow base and pump module, light monohull vessels can be utilised to execute installation and retrieval. The pump unit is Bornemann twin-screw design, service proven and modified for subsea use up to 2000-meter water depth, driven by an oil-filled Loher electric motor that provides efficient power with corresponding low weight. Some main pump features are flexible operation covering all gas-liquid ratios together with tolerance for slug flow and some sand. Of particular importance, compared to centrifugal pump designs, the twin-screw volumetric arrangement is able to maintain the pressure boost specification independent of gas content at the pump inlet, and without an upstream mixing tank.
