Abstract

PROCEDIMENTO PARA A REMOçãO DE SULFATO DE SóDIO DE UMA SOLUçãO DE FOSFATO A presente invenção descreve um procedimeno para a remoção de sulfato de sódio de uma solução fosfato que foi usada para absorção de SO2 a partir de gases de combustão, pelo que um precipitado se forma quando a solução de absorção é regenerada por evaporação.Neste procedimento, uma parte do precipitado é separada de sua slução e tratada com água e SO2 para transformação de hidrogeno fosfato de dissódio em di-hidrogeno fosfato de monosódio na solução aquosa, pelo que o sulfato de sódio permanece não dissolvido e é removido por filtragem, depois do que o filtrado é adicionado de volta ao prcoceso principal.
