Abstract: Process for producing sodium carbonate with ammonia and/or for producing refined sodium bicarbonate, wherein: a low CO2 content gas generated by a unit for producing sodium carbonate with ammonia and/or generated by a unit for producing refined sodium bicarbonate is enriched into a CO2-enriched gas by using a CO2 concentration module, such as an amine-type or ammonia or PSA or TSA or cryogenic distillation or membrane-type CO2 concentration module, and said CO2-enriched gas has an increased CO2 content of: +10% (at least) to +90% (at most), by volume on a dry gas basis relative to the CO2 concentration of the low content gas, and the CO2-enriched gas is subsequently recycled to the unit for producing sodium carbonate with ammonia and/or to the unit for producing refined sodium bicarbonate, to produce sodium carbonate, or sodium bicarbonate, or to carbonate at least one part of effluent from the unit for producing sodium carbonate and/or from the unit for producing sodium bicarbonate.

Abstract: The invention provides several processes for generating sodium carbonate compounds and ammonium sulfate in which the compounds are in a commercially viable and substantially pure form. In one embodiment, the process involves salting out sodium compounds in order to arrive at a high purity ammonium sulfate fertilizer. Several different processes are disclosed which include sodium ion reduction by ion exchange, refrigeration, ammonia shifting and evaporation. The processes disclosed also relate to adaptation of the processes to flue gas desulfurization and gypsum production. The processes disclosed herein result in the production of ammonium sulfate in a purity previously unobtainable by prior art methods.

Abstract: Process wherein a low CO2 content process gas generated by an ammonia-soda process unit or a refined sodium bicarbonate unit is enriched by using a Temperature Swing Adsorption CO2 concentration module into a CO2 enriched gas whose CO2 content is increased by at least +10% by volume on dry gas basis relative to the process gas, and which is subsequently recycled to the ammonia-soda process unit or optionally to the refined sodium bicarbonate unit, in order: to produce sodium carbonate, or sodium bicarbonate, or to carbonate at least part of effluent from the unit for producing sodium carbonate or bicarbonate. The TSA CO2 concentration module comprises a stator and a rotor connected to the stator and rotatable relatively to the stator about a rotational axis, the rotor comprising a plurality of sectors, each sector containing a separation device to separate at least part of the CO2 from the process gas which is led into the separation device, and each sector being fluidically connected with at least one rotary active valve.

Abstract: Verfahren zum Binden von gasförmigem CO 2 , wobei eine konzentrierte Salzsole zum Einsatz kommt. Dabei wird Ammoniak (NH 3 ) und das zu bindende CO 2 in die konzentrierte Salzsole eingeleitet. Es entsteht dabei Natriumhydrogencarbonat und/oder Natriumcarbonat, das aus der ammoniakhaltigen Sole entnommen werden kann. In weiteren vor- oder nachgeschalteten Teilprozessen können weitere Bestandteile des Rauchgases eliminiert oder deutlich reduziert werden.
