Abstract
Fuel oil containing sodium salt, potassium salt and solid matters is purified by separating the fuel oil into fuel oil and sludges by a centrifugal separating means, thereby removing the sludges from the fuel oil, and mixing the fuel oil freed from the sludges with water, and separating the resulting liquid mixture into fuel oil and water. Removal of the salts and the solid matters from the fuel oil can be attained at the same time very effectively with a reduced frequency of cleaning a filter or by omitting the use of the filter, with or without using an emulsion breaker.
