Loop
- In oil and gas production, the factors
determining the corrosion conditions include
temperature, pressure, chemical compositions
of the fluids, state of metal surface,
flow rates, and flow regimes. While it
is relatively easy to reproduce temperature,
pressure or chemistry of the fluids in
laboratory tests, other parameters are
more difficult to simulate, like the exact
nature of the flow and the intermittent
fluctuations in the flow.
- Multiphase flow designates the transport
of oil/water/gas in pipelines. In pipelines,
the different flow patterns that could
be observed are given in the following
figures. The flow pattern will depend
mainly on the gas and liquid velocities,
and gas/liquid ratio.
- Slug flow creates a tremendous turbulence
at the front of the slug. At the slug
front, gas bubbles are entrained in the
liquid. They impact and collapse on the
pipe wall, resulting in instantaneous
high shear. Therefore, slug flow generates
a very high shear stress at the pipe wall.
Applications:
- For studying behavior of materials
under multiphase flow conditions.
- Both laboratory and pilot plant scale
multiphase (oil, water, and gas) flow
loops / flow regimes.
- Simulation of ambient temperature and
pressure conditions to high temperature,
high pressure conditions (H2S testing
in fully pressurized Hastelloy C-276 components).
- For flow characterizations and corrosion
rate measurements.
- Facilities for undesirable reactions
are available to compare the effects of
up-flow and down-flow
