| 摘要 |
The crude oil pretreatment system of the present invention for removing sludge contained in crude oil comprises: a centrifugal separator (12) for receiving crude oil containing sludge, and stirring and rotating the crude oil in the internal space thereof, thereby separating 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 discharging 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 for receiving and storing the discharged crude oil from which sludge has been removed by the centrifugal separator, and the oil that has been recovered by the sludge oil recovery means and then discharged. The present invention enables the sludge contained in crude oil and various petrochemical products to be removed in advance and only the crude oil with low sludge contents to be loaded into a tanker or stored in a crude oil storage tank, thereby preventing problems caused by sludge in the subsequent processes of transportation, storage, and refining. |
