Abstract:

The corrosion results from corrosive sulfur compounds produced by sulfate reducing bacteria which are active in the sea water used to ballast the gasoline storage tanks. This report suggests that short term control can be effected by raising the pH of the sea water and thereby retaining any hydrogen sulfide in the ballast water. A pH of 9.5 to 10.0 is advisable and could be attained by the addition of one pound of sodium hydroxide per 1,000 gallons of water used for gasoline displacement.
