Multiphase Test 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 walls.  

Applications :

• For studying behavior of materials under multiphase flow conditions.
• Both laboratory and pilot plant scale multiphase (oil, water, and gas) flow loops or 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
