PURPOSE:A low-quality heavy oil which becomes gel at low temperatures is made sol by means of a sol crusher which can decompose and separate the oil-contaminant entangling mixture into fine sol particles, then centrifuged, whereby the impurities are readily removed from the low-quality oil of high viscosity. CONSTITUTION:A low-quality heavy oil of high viscosity is sent by means of pump 11 to the settling tank 12 in a ship. The heavy oil sinks in the tank and becomes gel at low temperatures. The gel oil as a oil-contaminants entangling mixture is made sol of fine oil particles using a gel crasher 13. The heavy oil in the sol state is sent through a heater 15 to a centrifugal cleaner 16 where the contaminants are removed. The resultant oil is sent to the service tank 17, then through the heater 18, the filter 19 and the pump 20, to the engine.
