Supercritical Fluid Propane-Butane Extraction Treatment of Oil Sludge

Supercritical Fluid Propane-Butane Extraction Treatment of Oil Sludge

The extraction process with propane: butane = 3: 1 (by mass) mixture in the liquid and supercritical fluid states was used to extract petroleum products containing 12.05 mass % of anhydrous oil sludge as solid particulates. The extraction was carried out at 85–160°С and 5–50 MPa. The desired oil pro...

Zusammenfassung:The extraction process with propane: butane = 3: 1 (by mass) mixture in the liquid and supercritical fluid states was used to extract petroleum products containing 12.05 mass % of anhydrous oil sludge as solid particulates. The extraction was carried out at 85–160°С and 5–50 MPa. The desired oil product contains 2.8 mass % of sulfur, it has a density of 880 kg/m 3 and a kinematic viscosity of 73.75 mm 2 /s at 20°С as well as start and end boiling point values of 43.6 and 325°С, respectively.
