Abstract

Procedimiento para la produccion de bicarbonato de sodio, carbonato de sodio y sulfato de amonio a partir de sulfato de sodio. La invencion proporciona diversos procedimientos para generar compuestos de carbonato de sodio, y sulfato de amonio, en los cuales los compuestos están en forma comercialmente viable sustancialmente pura. En una forma de realizacion, el procedimiento comporta precipitar compuestos de sodio mediante adicion de sal, para llegar a un fertilizante de sulfato de amonio de alta pureza. Se describen diversos procedimientos, incluyendo reduccion del ion sodio por intercambio ionico, refrigeracion, desplazamiento de amoniaco y evaporacion. Se describe también la adaptacion de los procedimientos a la desulfuracion de gases de la combustion y la produccion de yeso. Los procedimientos descritos en la presente resultan en la produccion de sulfato de amonio en una pureza que no podría ser previamente obtenida por los métodos de la técnica anterior.
