Abstract

A method of reducing the acidity, and fouling tendencies, of distillates when waste oil is distilled, which method comprises treating said oil while in a state when the oil has some water content, with one or more alkali metal salts of an acid that is weaker than sulphonic or with a hydroxide of an alkali metal salt.
