Hydrotreating of aromatic-extracted hydrocarbon streams
App. - Filed Jul 27, 2012 - Published Feb 7, 2013 - Refa Omer Koseoglu - Saudi
Arabian Oil Company
Abstract
Deep desulfurization of hydrocarbon feeds containing undesired organosulfur
compounds to produce a hydrocarbon product having low levels of sulfur, i.e.,
15 ppmw or less of sulfur, is achieved by first subjecting the entire feed to
an extraction zone to separate an aromatic-rich fraction containing a
substantial amount of the aromatic refractory and sterically hindered
sulfur-containing compounds and an aromatic-lean fraction containing a
substantial amount of the labile sulfur-containing compounds. The aromatic-rich
fraction is contacted with isomerization catalyst, and the isomerized
aromatic-rich fraction and the aromatic-lean fraction are combined and
contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone
operating under mild conditions to reduce the quantity of organosulfur
compounds to an ultra-low level.
