Apparatuses and methods for removing carbon dioxide and other pollutants from a gas stream are provided. The methods include obtaining hydroxide in an aqueous mixture, and mixing the hydroxide with the gas stream to produce carbonate and/or bicarbonate. Some of the apparatuses of the present invention comprise an electrolysis chamber for providing hydroxide and mixing equipment for mixing the hydroxide with a gas stream including carbon dioxide to form an admixture including carbonate and/or bicarbonate.

26 Process for the manufacture of sodium carbonate US10556604 2004-05-19 US07682588B2 2010-03-23 Paul Demilie
Process for the manufacture of sodium carbonate crystals comprising: the addition of solid sodium carbonate (1) to an aqueous solution comprising sodium bicarbonate and sodium carbonate; the crystallization and the separation of sodium sesquicarbonate crystals; (B, C) the crystallization of sodium carbonate crystals, (E) the amount of sodium carbonate added being adjusted so that the crystallization of sesquicarbonate crystals can be carried out without preliminary evaporation of the aqueous suspension.

A process for the production and recovery of crystalline sodium sesquicarbonate and of crystalline sodium carbonate monohydrate from aqueous liquors containing sodium carbonate and sodium bicarbonate. The crystalline products may optionally be heated or calcined to produce soda ash. The process is particularly suited for the recovery of soda ash from aqueous minewater streams obtained from solution mining of subterranean trona ore deposits.

30 Process for production of potassium carbonate sesquihydrate US09764920 2001-01-18 US06409982B1 2002-06-25 William J. Zuccarello; Elliot Block; Joseph A. Paluzzi; Kenneth R. Cummings
This invention provides a process for the production of dry free-flowing potassium carbonate sesquihydrate. The process involves the controlled hydration of high purity anhydrous potassium carbonate. The product of the process has at least about 90 percent particle size distribution in the range between about 200-1500 microns. The invention potassium carbonate sesquihydrate has properties which adapt the product for utility as a macromineral nutrient in animal feedstocks.
31 Process for the recovery of sodium carbonate from salt mixtures US642797 1984-08-21 US4564508A 1986-01-14 Michael J. Fairweather; Michael A. Rockandel; Abraham Sadan; Godefridus M. Swinkels
Mined salt mixtures comprising sodium-carbonate, -bicarbonate, -chloride, -sulfate, and -double salts, such as trona and burkeite, are leached with a bicarbonate-saturated solution and added carbon dioxide to selectively dissolve the sodium chloride, sodium sulfate and burkeite and to precipitate additional trona, leaving a leach residue consisting essentially of trona. The trona is calcined and dissolved, and the carbonate solution is purified, crystallized and dehydrated in a non-convective solar pond yielding high purity sodium carbonate monohydrate which is converted into dense soda ash. The brine solution from the leach may be treated for the recovery of a further amount of trona.
