A method for processing crude oil, characterized by comprising allowing crude oil to permeate through a membrane by immersing a membrane module in the crude oil in a processing tank and pressurizing the crude oil or by subjecting the crude oil to gravity filtering using the membrane, and removing the dehydrated oil obtained by the permeating from a gathering pipe, thereby enabling water content to be separated and removed from the crude oil sufficiently independently of the properties of the crude oil and mud to be separated and removed as well.
Cette invention concerne un procédé de traitement de pétrole brut qui se caractérise en ce que l'on fait passer le pétrole brut à travers une membrane. A cette fin, on immerge un module à membrane dans le pétrole brut qui se trouve dans un réservoir de traitement et l'on met ledit pétrole sous pression ou, encore, le pétrole brut est soumis à filtrage par gravité à l'aide de la membrane. On extrait ensuite le pétrole déshydraté obtenu par perméation à l'aide d'un tuyau collecteur. Ce système permet de séparer et d'éliminer le contenu en eau du pétrole brut d'une manière suffisamment indépendante des propriétés dudit pétrole brut, et il permet en outre de séparer et d'éliminer les boues.
