Visual scale tester system and trainers

The Visual scale tester system and trainers deposition and inhibitor performance in an incompatible brine mixture while controlling pH. Indeed, in the Visual scale tester system and trainers, the brines can be saturated with gases (CO2, Nitrogen) and the gas partial pressures controlled to achieve the desired pH level. The latter being a key factor in scale deposition, the Visual Scale Tester truly provides an accurate production representative scale deposition environment. The Visual scale tester system and trainers determines inhibitor efficiency from two phenomena: scale precipitation and scale deposition, achieved via a visual mixing cell and a capillary coil respectively. Scaling is attained from a coetaneous injection of incompatible brines (e.g. different salinities) followed by the injection of various possible solutions including those mentioned above. In addition to basic scale inhibitor testing, the device adequately mimics field conditions and can help to optimize the conflicting corrosion and scale control objectives. The mixing cell will allow the visualization of scaling and/or gunking, whereas the capillary coil will indicate deposition onset and rate, from pressure drop monitoring.
