Title:
METHOD FOR PRODUCING ULTRA-LOW SULFUR FUEL OIL
Document Type and Number:
WIPO Patent Application WO/2013/035200
Kind Code:
A1
Abstract:
[Problem] It is technologically difficult to reduce the sulfur content in a fuel oil to 10 ppm or less by a hydrodesulfurization method. Thus, the problem of the present invention is to provide a method for producing a fuel oil having a sulfur content at a level of 1 ppm or less at low cost and with high efficiency by a hydrodesulfurization method which uses hydrogen peroxide as a base material and employs mild reaction conditions.
[Solution] In a method according to the present invention, multiple oxidizing agents are mixed together using a premixer (A) to produce performic acid or peracetic acid, which is involved in the reaction, with high efficiency, subsequently a shear force is applied to a fuel oil and a peroxide (i.e., a fluid) by means of a stationary platen and forced agitation in reactors (B, C) to achieve the microparticulation, homogenization and dispersion of the reaction solution, subsequently a reacted sulfur compound is separated and removed by a coalescer (D), separators (E, I), and a deacidifying/dehydrating device (F), an adsorbing device (G) or a purifying device (J), an unreacted portion of the oxidizing agents is recycled into a line (3) through a line (14) or a line (17), and a fuel oil having a sulfur concentration at a level of 1 ppm or less is produced through a line (9).
