Example Embodiment
[0036] Example 1
[0037] use figure 1 The process uses solvents to separate oil sands, and the weight content of bitumen in oil sands is 20%
[0038] 5 kg of oil sand particles crushed to a size of 20mm by the high-temperature water crushing and desander of the spiral drum are sent to the primary stirring tank 3 and mixed with the organic solvent I at 25°C, stirred for 10 minutes, and then sent to the primary suspension separator 4. liquid-solid separation;
[0039] The organic solvent I is a mixture of n-octane and isobutyraldehyde, and the volume ratio is n-octane:isobutyraldehyde=1:5;
[0040] The mass ratio of organic solvent I to oil sand is 2:1;
[0041] The separated extraction phase is sent to the subsequent refining process 24, and the asphalt and organic solvent I are separated, and the organic solvent I is recycled;
[0042] The extraction rate of the obtained oil sand bitumen is 100%, and the solvent recovery rate is 100%.
