Abstract
Process for removing the nitrogen impurities from a liquid hydrocarbon mixture comprising introducing into a low volume mixer the hydrocarbons to be treated together with a dilute aqueous acid solution to form an emulsion, withdrawing said emulsion into a decantation zone where it breaks and recycling to the low volume mixer from 80 to 95% by volume of the aqueous acid solution coming from the decantation zone, so as to maintain in said low volume mixer a volume ratio of the hydrocarbons to the aqueous acid solution from about 0.3 to about 13, preferably from about 0.5 to about 4, and the pH of the aqueous acid solution from about 0.1 to about 1.5.
