Publication number: 20150060331Abstract: Methods for processing a hydrocarbonaceous feedstock flows are provided. In one embodiment, 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. The hydrocarbonaceous feedstock flow may be separated into 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 may be 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 injected counter current to the process flow as quench at one or more locations in one or more of the reaction zones.Type: ApplicationFiled: November 10, 2014Publication date: March 5, 2015Inventors: Paul A. Sechrist, Robert L. Bunting, Nicholas W. Bridge, RIchard K. Hoehn

Patent number: 8921627Abstract: A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils and animal oils, fats, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel or aviation boiling range fuel or fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A portion of the hydrogenated and deoxygenated feedstock is used as a non-flashing liquid quench stream to control the temperature of the hydrogenation and deoxygenation reactor.Type: GrantFiled: December 12, 2008Date of Patent: December 30, 2014Assignee: UOP LLCInventors: Paul A. Sechrist, Robert L. Bunting, Jr., Nicholas W. Bridge

Patent number: 5837208Abstract: Quench fluids being charged to a hydroprocessing reactor and liquid flowing downward within the reactor are admixed between the catalyst beds located in the reactor by an apparatus comprising three circular trays (16, 21, 22) and a mixing chamber (20). The mixing chamber receives liquid collected by the top tray and the quench material. The liquid effluent of the mixing chamber then falls upon a first distribution tray (21) while the vapor flows through an annular gap (17) between the first distribution tray (21) and the vessel wall (1). The two phases are then recontacted as they pass through a plurality of mixing caps (13) distributed over the surface of a lower second distribution tray (22).Type: GrantFiled: April 8, 1997Date of Patent: November 17, 1998Assignee: UOPInventors: Jeffrey Richard Grott, Robert L. Bunting, Jr., Richard K. Hoehn, Randall Forrest Goodspeed
