Abstract: A laundry treating appliance for treating laundry items according to an automatic cycle of operation can include a cabinet defining an interior and having an access opening providing access to the interior. A tub can be located within the interior and can at least partially define a liquid chamber. A drum is rotatably mounted within the liquid chamber and at least partially defines a treating chamber. A clothes mover is located within the treating chamber and rotatable about a vertical axis. The clothes mover can include a base and a barrel.

Abstract: Method and apparatus are disclosed which are improvements in the conventional method and apparatus for extracting water from a gas stream such as a natural gas stream by contacting the stream with a glycol to absorb the water, and then regenerating the glycol for further use in extraction by heating the moist glycol in a glycol regenerator to vaporize the water contained in same as steam. The improvement enables control of emissions of volatile organic compounds which have been absorbed by the glycol during contact with the gas stream, while minimizing the contaminants in the water streams produced. The vented steam and gaseous volatile organics are flowed from the glycol regenerator as input to a cooling condenser having successive air and water-cooled condensers, to produce a condenser water stream having a relatively high content of the organic compounds.

Abstract: Method and apparatus are disclosed which are improvements in the conventional method and apparatus for extracting water from a produced natural gas stream by contacting the stream with a glycol to absorb the water, and then regenerating the glycol for further use in extraction by heating the moist glycol in a glycol regenerator to vaporize the water contained in same as steam. The improvement enables control of emissions of volatile organic compounds which have been absorbed by the glycol during contact with the natural gas stream, while minimizing the contaminants in the water streams produced. The vented steam and gaseous volatile organics are flowed from the glycol regenerator as input to the bottom of a steam stripper column. The vapors from the top of the steam stripper column are flowed to a cooling condenser to produce a condenser water stream having a relatively high content of the organic compounds.

Abstract: A process for removing sulfur oxides from waste gas is provided. The gas is contacted with an activated sodium carbonate sorbent and, utilizing an alkaline ammonia liquor so as to reduce the flow rates and loss of alkalinity, the spent sorbent is regenerated with an alkaline earth metal oxide or hydroxide.

Abstract: A process for removing sulfur oxides from waste gas is provided. The gas is contacted with a sorbent selected from sodium bicarbonate, trona and activated sodium carbonate and, utilizing an alkaline liquor containing borate ion so as to reduce flow rates and loss of alkalinity, the spent sorbent is regenerated with an alkaline earth metal oxide or hydroxide.

Abstract: A process for removing sulfur dioxide from waste gas is provided. The gas is first contacted with an alkaline scrubbing liquor consisting essentially of a sorbent salt in which the cation is sodium or potassium, and one of the anions is borate. The clean gas is vented and the sorbent liquor regenerated for recycle by treatment with lime to precipitate insoluble calcium-sulfur compounds for disposal and regenerate the alkalinity of the scrubbing liquor.

Abstract: Sulfur dioxide is removed from a gas stream by contacting the gas with an aqueous solution containing sulfite anion, magnesium cation, and one or more other cations whose sulfite salts are more soluble than magnesium sulfite. The contacting solution is regenerated with magnesium oxide or hydroxide and then recycled.

Abstract: A sulfur dioxide containing gas stream is passed through a gas scrubber through which is circulated a scrubbing medium, preferably slurried, containing a reactant which reacts with the sulfur dioxide to produce sulfites and/or sulfates, a portion of which precipitate. At least a portion of the precipitated sulfites and/or sulfates are removed from the scrubbing medium which is rejuvenated with fresh reactant to maintain substantially steady state conditions in the scrubber. To minimize scaling in the scrubbing system, seed crystals of the sulfites and/or sulfates are introduced into the scrubbing medium, the seed crystals being in number and size so as to control the level of supersaturation of the scrubbing medium with respect to the sulfites and/or sulfates.
