Effect of drag-reducing polymers on Tubing Performance Curve (TPC) in vertical gas-liquid flows

This paper discusses the effect of drag reducing polymers on the Tubing Performance Curve (TPC) of vertical air-water flows at near atmospheric conditions. The effect of polymer concentration, liquid and gas flow rates on the pressure drop curve (Tubing Performance Curve) was investigated experimentally. The results showed that polymers tend to...

CO2 transport systems development: Status of three large European CCS demonstration projects with EEPR funding

This paper addresses technical and operational aspects pertaining to the transport of CO2. It deals with lessons learnt from the development of three large CCS demonstration projects: The UK-based Don Valley project, the Dutch ROAD project, and the Spanish Compostilla project. These projects were all selected by the European Commission in 2009...

Mitigation of terrain induced slugging using mixer devices

The present work focuses on experimental evidence of slug mitigation via various devices. The slug mitigation potential of a number of mixers was tested using a laboratory scale air/water setup to compare their effect on the incoming slugs just upstream of the separator inlet. Dedicated methods and key performance indicators were developed to...

Acoustic measurements of models of military style supersonic nozzle jets

Modern military aircraft jet engines are designed with variable-geometry nozzles to provide optimal thrust in different operating conditions, depending on the flight envelope. However, acoustic measurements for such nozzles are scarce, due to the cost involved in making full-scale measurements and the lack of details about the exact geometries...

Dynamics of carbon dioxide transport in a multiple sink network (GHGT-11)

As Carbon Capture and Storage slowly gets accepted and integrated as a mean for cleaner utilization of fossil fuels, the integration of capture, transport and storage becomes a key component to properly design a CO2 network. While the boundary conditions set by the capture and storage units have been the subject of much research, less attention...

Cold restart of viscous multiphase flowline by hot water flushing

The main objective of this paper is to understand the physical processes of shut-in and restart of viscous multiphase flowline. For this purpose, experiments were performed on shut-in and restart processes in the Multiphase Flow Rig at Statoil's research Centre in Porsgrunn. Real crudes were used with oil viscosity up to 30,000 cP at room...

Flow assurance studies for CO2 transport

In order to compensate for the relative lack of experience of the CCTS community, Flow Assurance studies of new CO2 pipelines and networks are a very important step toward reliable operation. This report details a typical approach for Flow Assurance study of CO2 transport pipeline. Considerations to take during the design of a pipeline are...

Dynamics of CO 2 transport and injection strategies in a depleted gas field

As Carbon Capture and Storage slowly gets accepted and integrated as a mean for cleaner utilization of fossil fuels, accurate knowledge of the transport of CO2 through pipelines and into wells becomes crucial. A representative North Sea transport and injection scenario into a depleted gas field is being analysed in this study through numerical...

Acoustic assessment of small-scale military-style nozzles with chevrons

With the emergence of more powerful fighter aircraft, supersonic jet noise reduction devices are being intensively researched. Small-scale measurements are a crucial step in evaluating the potential of noise reduction concepts at an early stage in the design process. With this in mind, the present study provides an acoustic assessment of small...

Liquid loading experiments with tube wall modifications

This paper discusses the multiphase flow mechanism responsible for gas-well liquid loading. It demonstrates that the conventional idea of droplet flow reversal (Turner et al. (1)) does not capture reality and that actual observations are better described by film flow reversal phenomenon. The benefits of different types of tubing wall...
