Title:
石油の処理方法および石油の処理装置
Document Type and Number:
Japanese Patent JP4050364
Kind Code:
B2
Abstract:
A petroleum processing method comprising the steps of: performing an atmospheric distillation of crude oil; collectively hydrodesulfurizing the resultant distillates consisting of gas oil and fractions whose boiling point is lower than that of gas oil in a reactor in the presence of a hydrogenation catalyst at 310 to 370 DEG C under 30 to 70 kg/cm<2>G (first hydrogenation step); and further performing hydrodesulfurization at lower temperatures (second hydrogenation step). When the second hydrogenation step is carried out only for the heavy naphtha obtained by separating the distillates after the first hydrogenation step, the second hydrogenation temperature can be in the range of 250 to 400 DEG C. The hydrodesulfurization having been performed for each of gas oil, kerosene, heavy naphtha and light naphtha in the art can be collectively and efficiently carried out, so that the oil refinery plant can be simplified and so that the cost of oil refinery equipment and running cost can be reduced. The petroleum processing method and apparatus of the present invention are especially useful when the amount of crude oil to be processed is small.
