Multiphase Flow Laboratory

Multiphase Flow Laboratory

Published 10 July 2017

The laboratory's main activity is flow assurance related research for the petroleum industry. It has contributed significantly to the development of multiphase flow simulators, and this is still an ongoing activity. Development of hydrate cold flow technology and sand transport studies are currently also main topics.

SINTEF Multiphase Flow Laboratory consists of a new medium-scale multiphase flow laboratory (A), an HPHT laboratory (B), a CO2 capture laboratory (C), and a new office building (D). Along with the large scale loop (E) this test facility will be a foundation for development in subsea oil and gas production in cold environments and over long transportation distances. SINTEF has established a truly unique subsea field development test laboratory which will be able to actively simulate flow assurance challenges for complex three-phase flows in a variety of pipe sizes and configurations. Well streams with compositions, rates, pressures and temperatures covering a wide industryrealistic range will be provided, as well as pipes, instrumentation and equipment to allow studies of all major Flow Assurance challenges.

The Large scale loop

The large scale loop is an industrial scale two-phase flow facility with EX control. The main features are a 500m long pipe rack and a 60 m high riser tower. A typical loop configuration has a total length of 1000 m.

The Medium scale loop

The medium scale loop is located indoor in a 60 m long laboratory hall. By using SF6 as the gas phase, gas densities equal to that of methane at 88 bar can be reached. This facility allows the study of multiphase flow in much greater detail than what is possible in large scale. For example: oil droplets, gas entrainment into oil and droplet entrainment into the gas phase, may be studied in this facility. A 11 m3 separator provides long retention times so that less easily separable fluids, such as viscous oils can be used.

The Real crude laboratory

The use of actual hydrocarbons breaks an important barrier enabling studies of complex chemistry-dependent phenomena.

SINTEF's Real Crude laboratory allows work on high pressure high-temperature (HPHT) fluids. The test loop consists of a 50m long 1in pipe which can be pressurized up to 100bar, and temperature-controlled room from -10ºC to +50ºC. In addition, high-pressure wheel-shaped flow loops are available up to 1000 bar.
