Abstract: This article conducts small oil separation devices study to separate parameter of oil sand in the help of self-developed water-based complexation reagent. The reagent concentration, heating temperature, heating time, the mass ratio of reagent and oil sand, and other factors on the separation of the impact of oil sands were studied. The result show that the yield of the product can be better under the optimum conditions as follows: the activator concentration of 4%, the mass ratio of reagent and oil sand of 1∶2, heating temperature of 85 ℃, heating separating time of 30 min. Under the condition, the oil and sand can be completely separated, and the extraction-rate is 94%. Activator can be recycled, and silt after processing achieves the backfill standard. The craft to solve the other processing methods produced oil, sand separation is not complete, silt, water pollution, environmental problems and so on a series of questions, so it has a popular value.
