The rate of carbon dioxide corrosion is conventionally recognized to be independent of the flow velocity at ambient temperatures. However in the presence of trace levels of dissolved oxygen (<15 ppb) it has been found that the rate of carbon dioxide corrosion can exhibit a strong flow dependence. Corrosion rates determined using the jet impingement technique illustrate a three fold increase in the corrosion rate in the presence of trace levels of dissolved oxygen (<15 ppb) at a Reynolds number of 61000. It is theorized that trace levels of dissolved oxygen affect the rate of hydration of carbon dioxide and may develop a surface which can facilitate the hydrogen evolution reaction. The practical implication of this interference can not be underestimated and is likely to be strongly associated with severe pitting and flow induced localized corrosion. Trace levels of dissolved oxygen are inevitably present in oil and gas process streams and most conventional laboratory testing of carbon dioxide corrosion.
