摘要： Process for producing sodium carbonate with ammonia and/or for producing refined sodium bicarbonate, wherein:
a low CO 2 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 CO 2 -enriched gas by using a CO 2 concentration module, such as an amine-type or ammonia or PSA or TSA or cryogenic distillation or membrane-type CO 2 concentration module, and said CO 2 -enriched gas has an increased CO 2 content of: +10% (at least) to +90% (at most), by volume on a dry gas basis relative to the CO 2 concentration of the low content gas, and the CO 2 -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.-
