Two-Stage Hydrodesulfurization Of Cracked Naphtha Streams With Light Naphtha Bypass Or Removal
US Patent:
7419586, Sep 2, 2008
Filed:
Nov 23, 2005
Appl. No.:
11/286578
Inventors:
Edward S. Ellis - Basking Ridge NJ, US
John P. Greeley - Annandale NJ, US

Assignee:
ExxonMobil Research and Engineering Company - Annandale NJ
International Classification:
C10G 45/04
US Classification:
208213, 208210, 208211, 208212, 208216 R, 208217, 208218
Abstract:
A process for the selective hydrodesulfurization of olefinic naphtha streams containing a substantial amount of organically-bound sulfur and olefins. The olefinic naphtha stream is selectively desulfurized in a first hydrodesulfurization stage. The effluent stream from this first stage is sent to a separation zone wherein a lower boiling naphtha stream and a higher boiling naphtha stream are produced. The lower boiling naphtha stream is sent through at least two more separation zones, each at a lower temperature than the preceding separation stage. The higher boiling naphtha stream, which contains most of the sulfur moieties, is passed to a second hydrodesulfurization stage wherein at least a fraction of the sulfur moieties are removed.
Selective Hydrodesulfurization And Mercaptan Decomposition Process With Interstage Separation
US Patent:
7507328, Mar 24, 2009
Filed:
Nov 23, 2005
Appl. No.:
11/286579

International Classification:
C10G 45/02, C10G 65/02
US Classification:
208210, 208212, 208213
Abstract:
A process for the selective hydrodesulfurization of olefinic naphtha streams containing a substantial amount of organically-bound sulfur and olefins. The olefinic naphtha stream is selectively desulfurized in a hydrodesulfurization reaction stage. The hydrodesulfurized effluent stream is separated into a light and heavy liquid fraction and the heavier fraction is further processed in a mercaptan destruction reaction stage to reduce the content of mercaptan sulfur in the final product.
Systems And Methods Of Pelletizing Heavy Hydrocarbons
US Patent:
2011018, Aug 4, 2011
Filed:
Feb 3, 2010
Appl. No.:

Assignee:
KELLOGG BROWN & ROOT LLC - Houston TX
International Classification:
C10L 5/06, B29B 9/00
US Classification:
44593, 425 6
Abstract:
Systems and methods for pelletizing a molten heavy hydrocarbon that can be extruded from a drop former to create a plurality of droplets that are subsequently quenched in a cooling media to create asphaltenic pellets. The asphaltenic pellets can be solidified by transferring heat from the droplets to the cooling media to provide the solid asphaltenic pellets. The solid asphaltenic pellets can then be separated from the cooling media which can be recycled for use.
