Filed:

Dec 7, 1999

Appl. No.:

09/457435

Inventors:

Larry L. Iaccino - Friendswood TX
Edward S. Ellis - Basking Ridge NJ

Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

C01G 6502

US Classification:

208 58, 208 57, 208210, 208211, 208212, 208251 H, 208254 H

Abstract:

The present invention relates to a process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. At least a fraction of up flowing vapor product is condensed to produce a condensate comprised of the heavier fraction of the vapor phase product stream and a lighter remaining vapor stream. The condensate and potentially the lighter remaining vapor stream are further hydroprocessed.

US Classification:

208212, 208 99, 208108, 208209, 208254 H, 208264, 208 48 R

Abstract:

A process for upgrading a liquid petroleum or chemical stream wherein said feedstream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The feedstream is treated so that it is substantially free of particulate matter and foulant precursors.

International Classification:

C10G 4500

US Classification:

208 58, 208 59, 208210, 208213, 208251 H, 208254 H, 585921

Abstract:

A process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The temperature of at least a portion of the liquid stream in the reactor is used to control the flooding characteristics of the reactor.

Filed:

Dec 5, 2001

Appl. No.:

10/011355

Inventors:

Larry Iaccino - Seabrook TX, US
Edward Ellis - Fairfax VA, US
William Lewis - Baton Rouge LA, US

International Classification:

C10G065/02
C10G067/06

US Classification:

208/210000, 208/089000, 208/058000

Abstract:

A process for hydroprocessing liquid petroleum and chemical streams in two or more hydroprocessing stages wherein the liquid and vapor products from the first stage are sent to a separation zone wherein a liquid phase fraction is separated from a vapor phse fraction which contains vaporized heary hydrocarbon components. The vapor phase fraction is passed to a sorption zone wherein at least a portion of the heavy hydrocarbon components is removed. Both the liquid phase fraction and the sorbed heavy hydrocarbon components are sent to at least one additional hydroprocessing stage.
