This invention reveals to the public the centralized sump oil and acid oil treatment process and system. The process consist of (1) the filter; (2) entry to reaction kettle, the sodium carbonate solution added at the time of air floatation till PH value keeps about 6.0-8.0; and emulsion splitter and flocculating agent added for further reaction; (3) suspension of air floatation and static settlement; (4) the international crude oil is collected after the detergent oil at the upper level of the reaction kettle is dehydrated under normal and reduced pressure; the wastewater is drained after filtering by the natural oil removal tank and the oil-water filter; the sludge is solidified by the cement and the quick lime and aluminium oxide are used as the coagulant aid for solidifying the sludge. The centralized treatment process of sump oil and acid oil not only greatly lowers the pollution of surroundings of the oilfield and corrosion of equipment, but also changes waste into valuable, reuses a great amount of crude oil and improves the economic benefits of the oilfield. The sludge solidified can be directly used for buildings.

Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery.
