The effluent treatment reactor has an effluent inlet to receive effluent from the exhaust conduit of the process chamber, a plasma cell having one or more electrodes electrically connected to a voltage source adapted to electrically bias the electrodes to couple energy to effluent received in the plasma cell, a scrubbing cell coaxially exterior to the plasma cell, the scrubbing cell having a scrubbing fluid inlet to introduce scrubbing fluid into effluent in the scrubbing cell and a scrubbing fluid outlet, and an effluent outlet to release the treated effluent.
Abstract:
An apparatus and a method of generating a carburizing atmosphere are provided which can stably generate a reformed gas containing carbon monoxide of high concentration that is suitably used as a carburizing atmosphere. As a reforming furnace, a first reforming furnace 14 and a second reforming furnace 15 which are connected in series are disposed. A first cooler 22 serving as moisture removing means for removing moisture in an intermediate reformed gas which is led out from the first reforming furnace and to be introduced into the second reforming furnace, and a hydrocarbon adding section 24 which adds hydrocarbon to the intermediate reformed gas are disposed in a passage between the first and second reforming furnaces. A raw material mixed gas in a condition where a mixture ratio of hydrocarbon is low is introduced into the first reforming furnace to cause a catalytic reaction, thereby generating the intermediate reformed gas. Moisture contained in the intermediate reformed gas is then removed away. Hydrocarbon is added to the intermediate reformed gas. The intermediate reformed gas is then introduced into the second reforming furnace to cause a catalytic reaction, to generate a carburizing atmosphere.
Abstract:
The present invention relates to a pozzolanic admixture containing ammonia-laden fly ash, method for making the pozzolanic admixture and method for controlling ammonia gas (NH3) emission from cementitious slurries using the pozzolanic admixture. The associated hypochlorite and ammonia reaction produces monochloramine and chloride salts at relatively low concentration levels harmless to concrete and concrete applications. The resulting monochloramine and chloride salt products are stable and do not dissipate into the air, thereby, eliminating odorous emission that is produced from cementitious slurry containing untreated ammonia laden fly ash. This invention relates to the method of adding hypochlorites (OClnull) in the form of calcium hypochloritenullCa(OCl)2, lithium hypochloritenullLiOCl, sodium hypochlorite NaOCl or trichloro-s-triazinetrionenullC3N3O3Cl3 to the ammonia-ladden fly ash at dosage levels, based on ammonia concentration in ash and stoichiometry, for a complete or partial oxidation of ammonia to eliminate, or respectively reduce, ammonia gas evolution from the high pH cementitious slurries.
Abstract:
There is disclosed a device for multiparallel synthesis or screening of a chemical library that includes at least one, and preferably more than one, plate with a two-dimensional or three-dimensional array of wells. Openings are provided in the side walls between at least some of the wells, through which the fluid can flow between adjacent wells. At least one inlet for each plate is provided whereby fluids can be introduced into the array of wells in each plate and flow between adjacent wells in each of the plates through the openings in the side walls.
Abstract:
A fuel reformer is operated in one mode of operation to generate and supply a particular quantity and/or composition of reformate gas to a first component such as a NOX trap, and then is operated in a different mode of operation to generate and supply and different quantity and/or composition of reformate gas to a different component such as a soot particulate filter. In a similar manner, the fuel reformer is operated in one mode of operation to generate and supply a particular quantity and/or composition of reformate gas to a fuel cell, and then is operated in a different mode of operation to generate and supply and different quantity and/or composition of reformate gas to an emission abatement device. A method of operating a fuel reformer is also disclosed.
Abstract:
A process for upgrading at least one of a Fischer-Tropsch naphtha and a Fischer-Tropsch distillate to produce at least one of a gasoline component, a distillate fuel or a lube base feedstock component. The process includes reforming a Fischer-Tropsch naphtha to produce hydrogen by-product and a gasoline component with a research octane rating of at least about 80. The process further includes upgrading a Fischer-Tropsch distillate using the hydrogen by-product to produce a distillate fuel and/or a lube base feedstock component.
Abstract:
A fuel processor system capable of circulating fuel processor system gases, such as reformate, anode exhaust, and/or combustor exhaust, through the fuel processor to provide a number of distinct advantages. The fuel processor system having a plurality of fuel cells discharging an H2-containing anode effluent and an O2-containing cathode effluent. A fuel processor is also provided for converting a hydrogen-containing fuel to H2-containing reformate for fueling the plurality of fuel cells. A catalytic combustor is positioned in series downstream from the plurality of fuel cells and a vaporizer reactor is coupled to the catalytic combustor. A bypass passage is finally provided that interconnects an outlet of at least one of the group consisting of the fuel processor, the plurality of fuel cells, the catalytic combustor, and the vaporizer reactor to the inlet of the fuel processor. The bypass passage is operable to circulate a fuel processor system gas to the inlet of the fuel processor.
Abstract:
The invention relates to a process and installation for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) mild hydrocracking in a fixed catalyst bed, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment (including desulfurization) of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Advantageously, the heavy fraction is sent into catalytic cracking. The process preferably operates with make-up hydrogen that is brought to stage c), and very advantageously all of the make-up hydrogen of the process in introduced in stage c).
Abstract:
The invention disclosed herein is a flow baffle for providing a generally uniform flow to a fluid within a catalytic reactor, which is characterized by a single flow channel. The invention, however, has general application to any single flow channel device. The flow baffle is inserted within the reactor in the single flow channel to cause the fluid flowing in the single flow channel to have a generally uniform flow field, instead of preferentially flowing down a periphery of the channel. The uniform flow field promotes the design optimization of the catalytic reactor.
Abstract:
A process for regenerating a spent catalyst having coke deposits thereon in a catalyst regeneration vessel having a dense phase and a dilute phase, wherein the process comprises the steps of: (a) contacting the spent catalyst with a primary oxygen-containing gas in the dense phase, thereby combusting the coke, resulting in the formation of a combustion gas comprising nitrogen oxides and carbon monoxide which further reacts, thus reducing a majority of the nitrogen oxides to form elemental nitrogen; and (b) contacting the combustion gas with a secondary oxygen-containing gas, and typically a shield gas, in the dilute phase, thereby oxidizing the remaining CO to CO2 without significant temperature rise in the dilute phase due to the after bum.
