Hydrodynamic correlations between pipe flow and rotating cylinder electrode (RCE) for oilfield corrosion -- Some insights
- Univ. of Tulsa, OK (United States)
Small scale, table top devices such as the rotating cylinder electrode (RCE) have received increased attention as a means for making decisions about material and inhibitor selections for oilfield applications. In order to utilize the corrosion data from an RCE to predict the behavior in a pipe geometry, it is necessary to establish correlations between the pipe flow velocity and the RCE rotation speed. Most often, correlations between the two geometries were attempted based on the equality of (1) the mass transfer coefficient or (2) the wall shear stress. The validity of these correlations is critically examined in this study for corrosion under different conditions. Relevant corrosion data o in this study and from the literature were used. A recently developed mechanistic model for predicting CO{sub 2} corrosion rates for carbon steels was also used for identifying the mechanism and rate controlling steps for corrosion under conditions of interest to the oil and gas industry.
