Abstract
processo de produção de ácido fosfórico. a invenção refere-se a um processo de produção de ácido fosfórico, que compreende um ataque de rocha fosfatada com ácido sulfúrico entre 70 e 90<198> c, com formação de uma primeira pasta de cristais de sulfato de cálcio di-hidrato, a fase aquosa ácida dessa pasta apresentando u mteor em p~ 2~ o~ 5~ livre compreendido entre 38 e 50% em peso e um teor em so~ 3~ livre inferior a 0,5% e superior a 0,05% em peso, uma conversão dessa primeira pasta por aquecimento a uma temperatura superior a 90<198> c, que dá lugar a uma segunda pasta formada de cristais de cálcio hemi-hidrato, e uma separação na segunga pasta entre um ácido fosfórico de produção, que apresenta um teor em so~ 3~ livre inferior a 2%, e uma torta de filtração á base de sulfato de cálcio hemi-hidrato.
