Experimental research on velocity and density properties of heavy oil mixed with hydrocarbon solvent

Summary The velocities and densities of heavy oil mixed with hydrocarbon solvent (diluent 12 wt% and propane 88 wt%) were measured and analyzed for a wide range of temperatures from 8°C to 90°C, pressures from 1 MPa to 48 MPa, and mixed hydrocarbon solvent from 5wt% to 80wt%. Velocities and densities of the mixture decrease with increasing temperature, decreasing pressure, and increasing weight fraction of the solvent. The 6 wt% of the solvent shows the highest effect to reduce velocity and density, and then, the effect reduces gradually.
