摘要： An exhaust air scrubber for removing dust, abraded product, and water-soluble constituents from process exhaust air may include in a single housing a cleaning stage that includes a droplet separator and a packing disposed below the droplet separator. The exhaust air scrubber may also include an inlet apparatus for process exhaust air disposed in a lower portion of the housing, a withdrawal apparatus for scrubbing solution, and a withdrawal conduit for cleaned exhaust air, with the withdrawal conduit beginning inside the housing above the cleaning stage, passing downward inside the housing, and passing out of the housing to an outside in the lower portion of the housing below the cleaning stage. The scrubber may further include a feed conduit for scrubbing solution in an upper portion of the housing above the cleaning stage.

摘要： A method and apparatus are provided for recovering an amine solvent from an acid gas stream. The apparatus includes a water wash recovery column, a nozzle for spraying water wash and an amine nucleation agent into the water wash recovery column and an inlet port for introducing acid gas into the water wash recovery column adjacent the lower end thereof. The method includes the steps of treating the acid gas stream in the water wash recovery column with a counter-current flow of water wash in an amine nucleation agent, discharging treated acid gas from an upper end of the water wash recovery column and collecting water wash, amine nucleation agent and entrained amine solvent from the acid gas stream and a sump at a lower end of the water wash recovery column.

摘要： A carbon dioxide capture system, fluid contactor and method are disclosed. In embodiments, a gas-liquid contactor unit is disposed along a process fluid flow axis and includes a contactor network of flow diversion barriers with flow voids for movement of process fluids therebetween. A plurality of heat exchange channels are provided in the flow diversion barriers to transport a heat exchange fluid through the contactor network. A heat exchange feed channel is provided to deliver feed of the heat exchange fluid to the heat exchange channels at multiple feed locations spaced along the flow axis. At least one heat exchange bypass channel may extend beyond the multiple feed locations to deliver a portion of the feed of the heat exchange fluid to additional heat exchange channels located downstream from the multiple feed locations for the heat exchange channels.

摘要： A system and apparatus for treating and disposing of produced water in conjunction with flared gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated in a scrubber with heat applied through a flare gas field burner, which uses field gas from oilfield operations. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system. The evaporated salts and solids are then treated via chemical stabilization in a mixing system with chemical reagents to prevent the residual form from being hazardous. The residual material is then stored and disposed of properly.

摘要： A gas inlet system for a wet gas scrubber includes a weir configured to deliver liquid to a scrubbing passage to wet the interior surface of the scrubbing vessel during operation of the gas inlet system. The weir include a weir duct and a weir trough extending at least partially around the weir duct to receive and at least partially fill with liquid during operation of the gas inlet system. The weir trough has an upper trough outlet in liquid communication with the upper weir duct inlet to deliver liquid from the weir trough into the upper weir duct inlet during operation of the gas inlet system. The weir trough also has a lower trough outlet below the upper trough outlet. The lower trough outlet is in liquid communication with the scrubbing passage to deliver liquid from the weir trough toward the scrubbing passage during operation of the gas inlet system.

摘要： Improved methods and systems are provided for the on-board removal of sulfur dioxide generated by a marine vessel. The method includes spraying an alkaline fluid into the flue gas to produce a saturated flue gas stream containing the alkaline fluid; and flowing the saturated flue gas stream containing the alkaline fluid through a venturi to cause the particulates in the flue gas to impact the alkaline fluid and react at least a portion of the sulfur dioxide with the alkaline fluid.

摘要： An integrated device for removal of both liquid-containing droplets and pollutants from a gas stream includes a plurality of passageways and a plurality of exposed surface portions, different ones of the surface portions disposed along different ones of the plurality of passageways. The plurality of passageways include an inlet and an outlet for the flow of a gas stream therethrough, wherein each passageway includes at least one segment configured to perturb the flow of at least a portion of the gas stream between the inlet and the outlet. Such gas perturbation enhances gas stream contact with the exposed surfaces. Portions of the exposed surfaces comprise a sorbent-polymer-composite material adapted for contact conversion of sulfur oxides to sulfuric acid droplets. The exposed surfaces are disposed to enhance the removal of liquid-containing droplets and contact conversion of sulfur oxides to sulfuric acid droplets.

摘要： An abatement apparatus and method are disclosed. The abatement apparatus for treating an effluent stream from a semiconductor processing tool comprises: a first treatment stage operable to combust the effluent stream to provide a combusted effluent steam and to treat the combusted effluent stream with water to provide a first stage treated effluent stream comprising treated fluid together with combustion particles and water; and a second treatment stage operable to receive the first stage treated effluent stream at an inlet and to separate centrifugally at least some of the combustion particles and the water from the treated fluid which is provided at a treated fluid outlet as a second stage treated effluent stream. In this way, particles and water may be removed effectively from the combusted effluent stream without the need for an inconvenient electrostatic precipitator. Instead, the second treatment stage provides for improved particle capture within a smaller footprint. Also, utilising water helps to retain the particles separately from the treated fluid.
