A method and apparatus is described for removing at least some contaminants from a hydrocarbon feedstock, such as a petroleum. The method includes treating the contaminated feedstock during flow through a supercritical reactor with supercritical water to facilitate the removal of at least some of the contaminants. The flow through the supercritical reactor is a continuous flow. L'invention concerne un procédé et un appareil pour éliminer au moins certains contaminants d'une charge d'alimentation hydrocarbonée, telle que le pétrole. Le procédé comprend le traitement de la charge d'alimentation contaminée pendant l'écoulement au travers d'un réacteur supercritique par de l'eau supercritique en vue de faciliter l'élimination d'au moins certains des contaminants. L'écoulement au travers du réacteur supercritique est un écoulement continu.
