Appl. No.:

09/724232

Inventors:

Jacques J. L. Romatier - Riverwoods IL
John A. Petri - Palatine IL

Assignee:

UOP LLC - Des Plaines IL

International Classification:

F28F 300

US Classification:

422200, 422198, 165166, 165173, 165DIG 355, 165DIG 356

Abstract:

A process and apparatus for indirectly exchanging heat with narrow channel in a heat exchange type reaction zone uses manifold space to interconnect the common ends of channels and to provide controlled distribution of additional reactants. The invention simplifies the operation and construction of the heat exchanging type reaction zone by directly communicating reaction channels and/or heating channels with a manifold located at the end of the channels. The manifold can provides the extra function of mixing additional reactants. The invention promotes simplified intermediate injection of reactants over tube and shell heat transfer arrangements that have been used for similar purposes. Improved process control has particular benefits for exothermic reactions. The narrow channels are preferably defined by corrugated plates. The reaction channels will contain a catalyst for the promotion of the primary reaction.

Appl. No.:

12/036553

Inventors:

John A. Petri - Palatine IL, US
Terry L. Marker - Palos Heights IL, US

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C07C 1/20

US Classification:

585240, 585241

Abstract:

A process has been developed for producing a hydrocarbon component useful as diesel fuel from biorenewable feedstocks such as plant oils and greases. The process involves hydrogenating and deoxygenating, i. e. decarboxylating and/or hydrodeoxygenating the feedstock to provide a hydrocarbon fraction useful as a diesel fuel. An optional pretreatment step to remove contaminants such as alkali metals from the feedstock can also be carried out. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.

Inventors:

John A. Petri - Palatine IL, US

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C10G 11/20

US Classification:

208113

Abstract:

Disclosed is a process for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors.

Filed:

Jun 30, 2008

Appl. No.:

12/165444

Inventors:

John Anthony Petri - Palatine IL, US
Peter Kokayeff - Naperville IL, US

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C10G 51/02

US Classification:

585263, 208 46, 208 49

Abstract:

A method of hydroprocessing hydrocarbons is provided using a substantially liquid-phase reactor having first and second catalyst beds with a heat transfer section positioned therebetween. The first and second catalyst beds and the heat transfer section are combined within the same reactor vessel. Each catalyst bed having an inlet temperature and an exit temperature and having a hydroprocessing catalyst therein with a maximum operating temperature range. The method hydroprocesses the hydrocarbons and removes sufficient heat from the hydrocarbons using the heat transfer section so that the exit temperature of the hydrocarbons existing the first catalyst bed is substantially maintained below the maximum operating temperature range of the hydroprocessing catalysts in the first bed and, at the same time, also providing the hydrocarbons to the second catalyst bed at the inlet temperature so that the exit temperature of the hydrocarbons at the exit of the second catalyst bed also does not exceed the maximum operating temperature range of the hydroprocessing catalyst in the second bed.

Abstract:

Apparatuses for processing a hydrocarbonaceous feedstock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feedstock flow is separated into an portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed is supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is admixed with effluent from previous stage to quench the hot reactor effluent before entering a second stage.
