Process For Recovering Olefins From Cat-Cracked Gas Without Accumulating Undesirable Oxides Of Nitrogen

View page
US Patent:
54441765, Aug 22, 1995
Filed:
Oct 28, 1992
Appl. No.:
7/967835
Inventors:
Dane C. Grenoble - Nassau Bay TX
Roy T. Halle - League City TX
William D. Thomson - Southampton, GB2
Assignee:
Exxon Chemical Patents Inc. - Linden NJ
International Classification:
C07C 700
F25J 300
US Classification:
585809
Abstract:
A safe, effective, and economical method is provided for recovering olefins from cat-cracked gases without accumulating dangerous amounts of nitrogen oxides. A stream of cat-cracked gas first is scrubbed to remove acid gases, including nitrogen dioxide (NO. sub. 2), and then is passed through a depropanizer fractionation tower. Hydrocarbons having four or more carbon atoms are recovered in the bottoms of the depropanizer, and the overhead from the depropanizer--which is composed of hydrocarbons having three or fewer carbon atoms--is sent to an absorber demethanizer tower. Hydrocarbons having two or more carbon atoms are recovered in the bottoms from the absorber demethanizer tower, where temperatures are no lower than about -45. 56. degree. C. (-50. degree. F. ). The overhead from the absorber demethanizer tower--which is composed of methane, hydrogen, and trace amounts of nitrogen oxide, C. sub. 2, and absorbent (C. sub.

Fouling Reducing Dual Pressure Fractional Distillator

US Patent:
53425090, Aug 30, 1994
Filed:
Sep 24, 1992
Appl. No.:
7/950622
Inventors:
Sheri R. Snider - Houston TX
David A. Bamford - Houston TX
Rimas V. Vebeliunas - Houston TX
Roy T. Halle - Houston TX
Robert D. Strack - Houston TX
Assignee:
Exxon Chemical Patents Inc. - Linden NJ
International Classification:
C10G 702
US Classification:
208351
Abstract:
A process flow sequence for the reduction of polymer fouling while maintaining efficient production levels wherein a dual pressure, dual column configuration is used to effect the reduction in polymer fouling. The dual pressure, dual column configuration of the invention uses a high pressure and a separate low pressure to isolate the desired fractions while effecting a reduction in the production of fouling polymers.

Method For Upgrading Steam Cracker Tars

View page
US Patent:
52156494, Jun 1, 1993
Filed:
May 2, 1990
Appl. No.:
7/517994
Inventors:
Dane C. Grenoble - Houston TX
Roy T. Halle - Houston TX
Martin L. Gorbaty - Westfield NJ
Harold W. Helmke - Kingwood TX
Assignee:
Exxon Chemical Patents Inc. - Linden NJ
International Classification:
C10G 5700
US Classification:
208 95
Abstract:
A process for the production of gaseous olefins which involves introducing a hydrocarbon feedstock stream into a high temperature thermal cracking zone to produce a high temperature cracked product stream, quenching the cracked product stream to stop the cracking reactions, injecting at least one HDD (hydrogen donor diluent) into the cracked product stream at or downstream of the point at which the reaction is quenched, recovering normally gaseous olefins from the cracked product stream, and recovering a liquid product stream containing a diminished asphaltene content.

Foulant Reducing Upstream Hydrogenation Unit Systems

View page
US Patent:
61075337, Aug 22, 2000
Filed:
Jun 9, 1997
Appl. No.:
8/871859
Inventors:
Rimas Virgilijus Vebeliunas - Houston TX
David Alan Bamford - Houston TX
Neil James Drummond - Dunfermline, GB
Sheri Renee Snider - Houston TX
Robert David Strack - Houston TX
Roy Thomas Halle - League City TX
Assignee:
Exxon Chemical Patents Inc. - Houston TX
International Classification:
C07C 503
C07C 508
C07C 509
C07C 704
US Classification:
585259
Abstract:
Process flow sequences for the reduction of equipment fouling in the fractional distillation of light end hydrocarbon components, such as those produced by pyrolysis or steam cracking, wherein conventional multiple hydrogenation unit configurations are replaced with upstream hydrogenation unit configurations. The upstream hydrogenation units of the invention are located at either side draws or in the reboiler circuit of deethanizers, in front-end demethanizer and front-end deethanizer sequences, or depropanizers, in front-end depropanizer sequences and obviate the need for most of the conventionally used hydrogenation units downstream.
