摘要： The detergent composition for petroleum refining apparatus in accordance with the present invention is one used as being mixed with a petroleum solvent when the inside of a petroleum refining apparatus is washed with the petroleum solvent in a nonaqueous system, wherein the detergent composition contains a surfactant having a solubility of at least 10 with respect to a diesel fuel at a temperature of 25° C. When this detergent composition for petroleum refining apparatus is used together with the petroleum solvent, soil components are rapidly impregnated with the petroleum solvent. Consequently, sufficient washing effects can be exhibited. As a result, the washing efficiency can be improved remarkably, whereby the washing time within the petroleum refining apparatus can be shortened greatly.
