Abstract:

The quantity of gaseous oxygen dissolved in water is generally known as Dissolved Oxygen. However, the oxygen may dissolve in other liquids too. To determine the concentration of Dissolved Oxygen in Gasoline a probe was used to estimate oxygen concentration at different experimental conditions. Comparing the experiments performed on Gasoline and Deionized Water it was found that for gasoline, the equilibrium point was reached earlier, while for the Deionized Water it took a long time for the initial reading to be attained after purging. In determining the mass transfer coefficients of Gasoline and Deionized Water it was found that Gasoline displayed a higher mass transfer coefficient value than Deionized Water. It is concluded that the increase in stirring speed, increases, the mass transfer coefficient and it is more prominent for gasoline. The aim of this work was to find gasoline’s ability to dissolve oxygen. From the research it was reckoned that the Dissolved Oxygen and free water present in the tanked Gasoline, could result in electrochemical corrosion over a period of time.

Keywords: tank corrosion, gasoline, dissolved oxygen, electrochemical, oil-water interface.
