A crude oil pretreatment system for removing sludge contained in crude oil includes a centrifugal separator (12) receiving crude oil containing sludge, and stirring and rotating the crude oil in the internal space thereof to separate the crude oil into a sludge component with a relatively higher specific gravity and a crude oil component with a relatively lower specific gravity and to discharge the sludge component and the crude oil component; a sludge oil recovery means for pressing the sludge discharged from the centrifugal separator and recovering the oil remaining in the sludge; and a crude oil storage tank receiving and storing the discharged crude oil from which the sludge has been removed by the centrifugal separator and the oil that has been recovered by the sludge oil recovery means to be discharged. The sludge contained in crude oil and various petrochemical products is removed in advance and only the crude oil with low sludge content is loaded into a tanker or stored in a crude oil storage tank, so that problems caused by sludge in the subsequent processes of transportation, storage, and refining can be prevented. |
