Removal of impurities from a hydrocarbon component or fraction










Image Number 3 for United States Patent #6483003.

A process for removing impurities from a hydrocarbon component or fraction comprises mixing, in a liquid-liquid extraction step, an impurity-containing liquid hydrocarbon component or fraction, as an impure liquid hydrocarbon feedstock, with an acetonitrile-based solvent. Thereby, at least one impurity is extracted from the hydrocarbon component or fraction into the solvent. There is withdrawn from the extraction step, as a raffinate, purified hydrocarbon component or fraction, while there is withdrawn from the extraction step, as an extract, impurity-containing solvent.
