Abstract
PURPOSE: To separate easily oil by a method such as settling or centrifugal separation by adding oil containing more than a specified proportion of aromatic hydrocarbons to petroleum waste oil containing water, sludge, etc.
CONSTITUTION: Aromatic hydrocarbon oil containing more than 50% by weight, preferably 70% by weight of aromatic hydrocarbons of residual oil obtained by distilling a distillate within the range of from for light oil to xylene, is added to water-in-oil type petroleum waste oil containing water and sludge as solid resulting from oil tank washing step to mix, whereby W/O emulsion is broken, sludge settles and the separation of oil from water becomes easy. Then oil, water and solids can be separated by a method such as settling or centrifugal separation. Waste oil containing water can be separated without using much energy source and the recovered oil can be used as fuel.
