OLI has developed the world’s
first predictive rates of general corrosion and localized models.
OLI’s corrosion technology allows corrosion engineers and
specialists to understand the effect of the corrosion environment
on the likelihood and extent of corrosion. Using this unique capability,
users can:
o Anticipate the occurrence and extent of corrosion
o Locate corrosion “hot spots” for monitoring
o Interpret the results of plant coupon and monitoring data
o Reduce corrosion laboratory time and expense
o Conduct virtual experiments without risking the lab and plant
o Rapidly identify corrosion causes and corrective actions
o Simulate and predict the effects of process and material changes
o Optimize process conditions to minimize corrosion damage
The mechanistically-based model is made possible
by refinements to the OLI Engine to include rigorous redox chemistry
and predictive models for transport properties such as electrical
conductivity, viscosity, and diffusivity. The corrosion rate prediction
model is based first on an accurate thermodynamic view of corrosion,
precisely defining the conditions of activation and passivation
at the surface.

Then by taking into account all of the partial electrochemical and transport
processes in the bulk aqueous phase and in the boundary layer at the metal/fluid
interface, as well as the presence or absence of passive films, the model
calculates the ion transport and hence the corrosion rate at the surface.
CorrosionAnalyzer allows the prediction of rates of general
and localized corrosion as a function of pressure, temperature, composition,
and flow conditions. The software tool also provides real solution stability
(Pourbaix) diagrams and theoretical polarization curves to aid the engineer
and corrosion specialist in understanding the mechanism, causes, and possible
fixes for the corrosion situation being studied.
CorrosionAnalyzer is available now for a broad array
of common chemical systems and for carbon and stainless steels, and nickel-based
alloys. Under a research award from the US Department of Energy, OLI is
expanding the applicable metallurgy and chemistry to include essentially
all of the alloys and environments of industrial interest.
