In open-pit oilsands operations the chloride concentration in the bitumen is a function of the
water remaining in the bitumen. This water is a composition of the connate water in the ore
and the process-affected water used in the extraction process. In order to predict future
chloride in bitumen concentrations, the chloride concentration in the impounded processaffected
water must be predicted. This requires the ability to model the inventory of both the
process-affected water and the chlorides in it. Being able to predict the chloride concentration
for a given water content in the bitumen allows operators to quantify the corrosion impact on its
operations.
