<P>PROBLEM TO BE SOLVED: To provide a liquid fuel which has been desulfurized and into which a limited combustible gas is mixed. <P>SOLUTION: A liquid fuel desulphurization apparatus includes: a primary liquid fuel tank 6 with a fixed quantity of Vnom and a volume of Vmax, in which a liquid fuel with a temperature of T4 is stored; a desulfurizer 4 with a volume of Vd which is filled with a desulfuring agent at a filling rate α and is not less than a desulfurizer operating temperature T1 during operation; a pump 7 for supplying liquid and increasing pressure, which supplies liquid fuel in the primary liquid fuel tank 6 to the desulfurizer 4 and of which operation is stopped when it is not more than a pump operation stopping temperature of T3 that is less than T1 during decreasing temperature; a gas and liquid separator 11 including a main fuel and vapor separator 81 and a bypass fuel and vapor separator 82; and a liquid fuel recycling piping 45 extending from the liquid phase of the bypass fuel and vapor separator 82 to the primary liquid fuel tank 6, in which Vmax≥Vnom+Vd×(1-α)×(ρ3-ρ1)/ρ4 is satisfied assuming that liquid fuel densities are ρ1, ρ3, and ρ4 at the temperatures T1, T3, and T4, respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT |
