Patent number: 9285113Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.Type: GrantFiled: November 6, 2014Date of Patent: March 15, 2016Assignees: L'Air Liquide Société Anonyme Pour L'Étude Et L'Exploitation Des Procedes Georges Clause, American Air Liquide, Inc., Air Liquide Advanced Technologies U.S. LLCInventors: Taekyu Kang, Vivek Gautam, Rajeev S. Prabhakar, Benoit Grand, Bertrand Leroux, Magnus Mortberg, Nicolas Docquier

Patent number: 9050551Abstract: A method of removing contaminants from a gas stream utilizing a supersonic venturi including a converging section, a throat, and a diverging section is provided. A contaminated gas stream and a scrubbing liquid stream are introduced into the converging section, thereby forming a mixed stream which experiences choked flow upon exiting. The choked mixed stream is introduced into the throat section wherein the scrubbing liquid is contacted with the contaminated gas stream. The contaminated scrubbing liquid stream is removed from the supersonic venture scrubber, and an essentially pure gas stream is removed from the diverging section. A flow modification device may be introduced into the throat section. The flow modification device may be either axially or radially adjustable in order to effect the atomization of the scrubbing liquid and/or the contacting of atomized scrubbing liquid with the contaminated gas stream within the throat section.Type: GrantFiled: October 28, 2011Date of Patent: June 9, 2015Assignees: American Air Liquide, Inc., Lurgi GmbHInventors: Vivek Gautam, Magnus Mortberg, Jan Hagemann, Stefan Walter

Patent number: 8827691Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.Type: GrantFiled: July 31, 2010Date of Patent: September 9, 2014Assignees: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges Claude, American Air Liquide, Inc.Inventors: Rajeev S.

Patent number: 8632621Abstract: A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase.Type: GrantFiled: December 31, 2010Date of Patent: January 21, 2014Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Vivek Gautam, Kenneth Kaiser, Luc Jarry, Remi Pierre Tsiava

Publication number: 20130082210Abstract: A first carbon containing substance, which may be scrap tires, is introduced to pyrolitic reactor. The pyrolitic reactor produces at least a tar/char stream and a pyrolysis oil stream. Pyrolysis oil stream may also be combined with hydrogen stream and hydrotreated to produce synthetic diesel, synthetic jet fuel, or synthetic gasoline. At least a portion of hydrogen/carbon monoxide stream may be separated to provide hydrogen stream. An oxidant containing first gas may be oxygen or an oxygen rich stream. Gasification reactor may be a fluidized bed reactor, moving bed reactor, double fired reactor, entrained bed reactor or molten bath reactor. Pyrolitic reactor and gasification reactor may be thermally linked, with the exothermic pyrolitic reactor providing at least a portion of the heat required by endothermic gasification reactor.Type: ApplicationFiled: September 30, 2011Publication date: April 4, 2013Inventors: Vivek GAUTAM, Magnus Mortberg
