CRUDE OIL PROCESSING APPARATUS AND CRUDE OIL PROCESSING METHOD

摘要

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.
