Abstract (en)

[origin: WO03050213A1] The invention concerns a pretreatment method of emulsified fuel,wherein an emulsified fuel which is emulsified by adding water and surface active agent to Orinoco tar is heated to 70 °C to 95 °C and,at the same time,introduced in a centrifugal separator at a flow rate of 0.35 Q to 1.0 Q for eliminating impurities contained in the emulsified fuel. Provided that Q is the actual capacity of the centrifugal separator in case of clarifying in the centrifugal separator a heavy oil of 380 cSt in viscosity at 50 °C by heating to 98 °C.
