摘要： A process is disclosed for converting dilute brines of sodium carbonate and sodium bicarbonate to form feed solutions from which sodium based chemicals may be recovered. The sodium bicarbonate in a dilute brine is neutralized and the brine then fortified with calcined trona to form a feed liquor concentrated in sodium carbonate from which sodium based chemicals may be recovered in a Monohydrate or other crystallization process.

摘要： A process for producing valuable sodium-based chemicals from a brine containing sodium carbonate and sodium bicarbonate, such as those containing from about 8% to about 20% total alkali obtained by contacting water with an underground trona formation by heating the brine at about 100.degree. C. to about 140.degree. C. to evaporate water, convert sodium bicarbonate to sodium carbonate and to drive off resulting carbon dioxide, reacting the brine with reduced sodium bicarbonate with an aqueous sodium hydroxide solution in amounts to convert essentially all of the remaining sodium bicarbonate in the brine to sodium carbonate, cooling to about 5.degree. C. to about 25.degree. C. to precipitate sodium carbonate decahydrate crystals, separating the crystals from their mother liquor, melting the separate crystals to form a sodium carbonate solution, heating the solution to from above about 60.degree. C. to below 110.degree. C. to evaporate water, precipitating sodium carbonate monohydrate crystals, separating the sodium carbonate monohydrate crystals from their mother liquor and calcining them to soda ash which is recovered as a product. The sodium hydroxide used in the above process is formed preferably by causticizing sodium carbonate values with calcium oxide or calcium hydroxide in a separate but parallel operating causticizing circuit.

摘要： Systems and methods for drilling a well bore in a subsea formation from an offshore structure positioned on a water surface with a drill string that is suspended from the structure and includes a bottom hole assembly adapted to form a top hole portion of the well bore. A drilling fluid source on the offshore structure supplies drilling fluid through the drill string to the bottom hole assembly where the drilling fluid exits from the bottom hole assembly during drilling and returns up the well bore. A suction module is disposed at the sea floor and collects the drilling fluid emerging from the well bore. A pump module is disposed on a return line, which is in fluid communication with the suction module, at a position below the water surface and above the sea floor. The pump module is operable to receive drilling fluid from the suction module and pump the drilling fluid through the return pipe to the same offshore structure or a different offshore structure.
