Open Surface Flotation Method for Extracted Crude Oil

Details

• Personal Author:

• Description:
  A method for the separation of extracted viscous crude oil placed in a reservoir of a opened cell. Materials such as oil shale, oil sand, or tar sand may be involved. Hot water is introduced to the top surface of the reservoir material in the cell while steam is injected into a steam gallery running through the cell. The hot water and steam may contain a surfactant. The bouyancy of the crude oil creates an artificial water drive which causes the water and oil to "flip-flop" so that the oil rises to the top of the reservoir and separates from the remainder of the reservoir material. This separated oil may be removed from the cell and the remaining material disposed of. [Description provided by NIOSH]
