| Methods for sealing undesirable transverse fractures enlarged and/or created during lithological displacement of an underground water-soluble evaporite stratum by hydraulic pressure greater than overburden pressure at an evaporite/non-evaporite strata interface, comprising injecting and maintaining a sealing agent into these undesirable fractures to form a solidified matter in situ and ultimately seal them, while forming a main free surface at the interface suitable for initiating solution mining of the evaporite stratum. The solidified matter may be crystallized, precipitated, compacted, agglomerated, cross-linked, coagulated, water-swollen, and/or cemented matter, or may include a wall-building matter with the mineral on fracture faces. The sealing agent may comprise at least one component of the mineral and/or the non-evaporite. The evaporite stratum is preferably a trona stratum overlying an oil shale stratum. The sealing agent may comprise dissolved and/or solid trona, trona tailings particles, and/or water-swelling particles. | ||||||

| Methods for removing carbon dioxide and other pollutants from a gas stream are provided. The methods include obtaining hydroxide in an aqueous mixture, mixing the hydroxide with the gas stream to produce bicarbonate products or a combination of carbonate and bicarbonate products in an admixture, separating the products from the admixture, and using the products to perform ion-exchanges with one or more group-1 or group-2 salts to precipitate carbonates, wherein obtaining the hydroxide comprises obtaining a group-1 or group-2 salt; mixing the salt with acid and water, acid and steam, or acid, water, and steam to produce a protonated brine solution; and electrolyzing the protonated brine solution to produce a hydroxide; and wherein mixing the hydroxide with the gas stream comprises altering the product equilibrium to favor the production of bicarbonate products. | ||||||

| 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. | ||||||

| A process is described for producing sodium-based chemicals from a brine containing sodium carbonate and sodium bicarbonate by heating the brine to evaporate water and drive off carbon dioxide and obtain a solution that will crystallize sodium sesquicarbonate, cooling the solution, precipitating sodium sesquicarbonate crystals and separating a first mother liquor from the sesquicarbonate crystals. The first mother liquor is then cooled to a lower temperature to precipitate sodium carbonate decahydrate crystals, the decahydrate crystals are separated from a second mother liquor and the decahydrate crystals are recovered for use in the manufacture of sodium-containing chemicals, such as sodium carbonate monohydrate, anhydrous sodium carbonate or soda ash. | ||||||

| A method for production of absorptive particles of Wegscheider's Salt (Na.sub.2 CO.sub.3.3NaHCO.sub.3) having low bulk density and acceptable flow properties, by reaction of anhydrous sodium carbonate particles with water and carbon dioxide is disclosed. Particles of anhydrous sodium carbonate having a bulk density less than about 750 g/l are contacted with water up to 1.55 times the stoichiometric amount of water required for the formation of sodium carbonate monohydrate. Carbon dioxide is added in two stages; in the first, the reaction zone is maintained at ambient temperatures, the second, the reaction zone is preheated and the reaction temperature is maintained at between about 90.degree. and 105.degree. C. until at least about 50 weight percent Wegscheider's Salt is produced. Water is added to the carbon dioxide in the second stage if less than about 1.20 times the stoichiometric amount of water is added to the particles of anhydrous sodium carbonate in the first stage and when about 1.20 to 1.55 of the stoichiometric amount of water is added to the particles of anhydrous sodium carbonate in the first stage substantially dry carbon dioxide is used in both stages. 2 | ||||||
