Abstract

UN METODO CONTINUO DE PRODUCIR BICARBONATO SODICO.SE PRODUCE INTRODUCIENDO SESQUICARBONATO SODICO SOLIDO Y/O SAL DE WEGSCHEIDER EN UNA SUSPENSION DE INVERSION, SATURADA CON RESPECTO AL BICARBONATO Y QUE CONTIENE AL MENOS 10 EN PESO DE SOLIDOS, PARA EFECTUAR LA RAPIDA Y COMPLETA CONVERSION DE LOS SOLIDOS DE ALIMENTACION EN BICARBONATO SODICO CRISTALINO, QUE SE RECUPERA DE LA SUSPENSION. SE INTRODUCE DIOXIDO DE CARBONO EN EL LIQUIDO DE INVERSION PARA MANTENER SU COMPOSICION EN UN VALOR RELATIVAMENTE CONSTANTE, PREFERENTEMENTE EN UNA REGION DEL DIAGRAMA DE FASES MA2CO3 - NAHCO3 - H2O QUE MINIMICE LA PRESION PARCIAL DE EQUILIBRIO DEL VAPOR DE CO2 POR ENCIMA DE TAL LIQUIDO.
