EIP Circulating Apparatus
The EIP (Emulsion Inversion Point) apparatus is used in G205 testing. The contained loop apparatus circulates a crude brine mixture under atmospheric conditions at controlled circulation rates. Brine is added in incrementally and the point at which the emulsion changes from a oil external to water external phase is determined by resistance measurement across to two control pins.
The apparatus is used to create a partitioned brine with suspended oil to evaluate the corrosion rate in an RCE experiment. This allows for determination of the potential corrosivity versus inhibitory effect of a crude.
