Refining method and its configuration |
(57) The present invention relates to a refinery for hydrotreating of petroleum fractions,
and more particularly, a refining method and a refinery configuration comprising a
step for distillation of a crude oil to separate a residue and a distillate and a
step for hydrotreating the distillate at once in a single hydrotreating unit. If compared
to the conventional wherein crude oil is distilled into several fractions and hydrotreating
is carried out on each fraction independently, the present invention can simplify
a refinery configuration and achieves compact plant with low capital investment cost,
even for a small scale refinery.
