Abstract
Aerobic fungal growth in hydrocarbons contaminated with water is prevented by addition thereto of an additive comprising boron and a hydrocarbyl-substituted succinimide in which the hydrocarbyl substituent is of a size sufficient to impart hydrocarbon solubility.
Claims11
A process for the prevention of aerobic fungal growth in hydrocarbons selected from diesel fuels, heavy marine fuels and fuel oils, said hydrocarbons being in storage and contaminated with water, said process comprising the step of adding to said hydrocarbons an additive comprising boric acid or a salt thereof and a hydrocarbyl-substituted succinimide in which the hydrocarbyl substituent contains from about 40 to 150 carbon atoms, said additive being used in an amount sufficient to provide up to 500 ppm wt in the hydrocarbons.
