Abstract

A system for treating tar sand involving a centrifuge where under centrifugal force solvent treated tar sand and water form a three layer system of wet sand, water, and petroleum, where solvent solubilized hydrocarbons are stripped from the wet sand layer, passed through the water, and into the petroleum layer. The hydrocarbons are skimmed from the hydrocarbon layer and recovered.
