A method for processing a flowback composition stream from a well head includes controlling a first flow rate of the flow back composition stream to a second flow rate by regulating the flowback composition stream from a first pressure to a second pressure. The method also includes separating the flowback composition stream into a first gas stream and a condensed stream. The method includes discharging the condensed stream to a degasser and degassing a carbon dioxide rich gas from the condensed stream. The method also includes mixing the carbon dioxide rich gas stream with the first gas stream to produce a second gas stream. The method includes controlling a third flow rate of the second gas stream by regulating a third pressure of the second gas stream to a fourth pressure that is different than the third pressure.

[object Object]

Disclosed herein is a system for reducing NOemissions comprising a fuel tank in fluid communication with a fuel converter, wherein the fuel converter is located down stream of the fuel tank and wherein the fuel converter comprises a catalyst composition that is operative to continuously convert heavy hydrocarbon molecules having 9 or more carbon atoms per molecule into light hydrocarbon molecules having 8 or less carbon atoms per molecule; a selective catalytic reduction catalyst reactor in fluid communication with the fuel converter and located downstream of the fuel converter; and an engine in fluid communication with the fuel tank and the selective catalytic reduction catalyst reactor, wherein the engine is located downstream of the fuel tank and upstream of the selective catalytic reduction catalyst reactor.

The disclosed embodiments relate to a method and system for regeneration of a catalyst. The system includes an engine that creates an exhaust stream and a fuel supply adapted to supply a fuel stream to the engine. A reactor includes a catalyst and is in fluid communication with the engine to receive the exhaust stream. A sensor senses a system parameter and produces a signal corresponding to the system parameter. A controller receives the signal and directs at least a portion of the exhaust stream or at least a portion of the fuel stream to the catalyst to control a regeneration operation based on a value of the system parameter sensed by the sensor.

Method and system for regeneration of a catalyst

A method comprises injecting a reductant stream comprising a hydrocarbon reductant and water into an exhaust chamber comprising a nitrogen oxide-containing exhaust stream; contacting a composition comprising the reductant stream and exhaust stream with a catalyst; and decreasing a concentration of the nitrogen oxide in the composition comprising the reductant stream and exhaust stream. An exhaust stream treatment system, comprises an exhaust chamber comprising a catalyst; an exhaust stream comprising a nitrogen oxide; and a reductant stream comprising a hydrocarbon reductant and water.

A catalyst system for the reduction of NOx. is provided. The system comprises a catalyst in a first zone comprising a catalyst support, a catalytic metal comprising gallium, and at least one promoting metal selected from the group consisting of silver, gold, vanadium, zinc, tin, bismuth, cobalt, molybdenum, tungsten, indium and mixtures thereof; a catalyst in the second zone comprising a second catalyst support, a second catalytic metal selected from the group consisting of indium, copper, manganese, tungsten, molybdenum, titanium, vanadium, iron, cerium and mixtures thereof The catalyst system further comprises a gas stream comprising an organic reductant. The catalyst system may further comprise a catalyst in a third zone; the catalyst comprising a third catalyst support and a third catalytic metal selected from the group consisting of platinum, palladium, and mixtures thereof. A method for reducing NOx utilizing the catalyst system is also provided.

A catalyst system comprising a catalyst and a reductant is disclosed. The catalyst comprises a metal oxide catalyst support, a catalytic metal oxide, and a promoting metal. The catalytic metal oxide comprises gallium oxide, indium oxide or a combination of the two. The promoting metal comprises at least one of silver, cobalt, vanadium, molybdenum, tungsten, zinc, tin and bismuth. The catalyst comprises about 5 to about 31 mol % catalytic metal oxide and about 0.5 to about 9 mol % promoting metal. The reductant comprises a fluid hydrocarbon having at least 4 carbon atoms. Also disclosed is a process for reducing NOto Nusing the disclosed catalyst system by mixing NOwith a reductant and passing the mixture through a catalyst of the disclosed catalyst system.

Method and apparatus for recovering and purifying a solvent used in an article cleaning appliance are provided. The method allows passing solvent-based cleaning fluid from a wash basket through a coarse filter configured to remove relatively large particulates from the cleaning fluid. The method further allows passing cleaning fluid from the coarse filter through a particulate filter configured to remove relatively fine particulates from the cleaning fluid. An aqueous phase that may be present in the cleaning fluid is separated by decanting and coalescing through a separator/filter assembly. The cleaning fluid may then be passed through a regeneration cartridge for removing any water that may remain in the cleaning fluid, and for adsorbing organic contaminants that may be present in the cleaning fluid. Recovered solvent may be stored in a tank for subsequent use in a cleaning process performed by the appliance.
