To provide a production apparatus for producing a colorless low-sulfur kerosene-light oil base material without reducing a treatment amount or without using a hydrodesulfurization catalyst in a large amount, and to provide a production method.
This method for producing a colorless low-sulfur kerosene-light oil base material comprises hydrodesulfurizing a kerosene-light oil in a plurality of hydrodesulfurization devices A-1, A-2, obtaining the low-sulfur kerosene-light oil from the hydrodesulfurization devices as a colorless low-sulfur kerosene-light oil base material, when the hydrodesulfurized low-sulfur kerosene-light oil is not colored, and decoloring the low-sulfur kerosene-light oil from the hydrodesulfurization devices in a decoloration treatment device B-1, when the low-sulfur kerosene-light oil obtained by hydrodesulfurizing in a certain hydrodesulfurization device among a plurality of the such devices is colored. The production apparatus for producing the colorless low-sulfur kerosene-light oil base material is characterized by comprising a plurality of hydrodesulfurization devices for hydrodesulfurizing a kerosene-light oil fraction to obtain a low-sulfur kerosene-light oil, and the less number of decoloration treatment devices for decoloring the low-sulfur kerosene-light oil from the hydrodesulfurization devices than that of a plurality of the hydrodesulfurization devices.
