Abstract

PROCESSO DE OBTENçãO DE áCIDO SULFúRICO A PARTIR DE BATERIAS USADAS. Notadamente automotivas, que compreende as seguintes etapas: a solução de ácido sulfúrico proveniente do corte de baterias passa por um leito de secagem (filtros rápidos), que é composto por uma camada de brita, bidim e areia para a retenção das partículas sólidas, sendo que após a passagem pelos filtros rápidos a solução segue para um reator onde sofre um processo de decantação forçada para a retenção de metais pesados e contaminantes; o processo de decantação forçada é realizado da seguinte forma para cada 10.000 litros de solução de ácido sulfúrico sob agitação, adiciona-se 20 litros de hidróxido de alumínio, 20 quilos de cal (na forma de leite de cal), 2 litros de policloreto de alumínio (floculante) e 200 gramas de ácido acrílico acrilamida (polimero, utilizado diluído em água) deixa-se 40 minutos em repouso para a decantação, logo após a decantação passa o sobrenadante em um bag filter com filtro de manta de polietileno, depois em um filtros de cartuchos de 5 micras, então é enviado para um reservatório e armazenada; o decantado é enviado para leitos de secagem para a retenção dos materiais floculados e o percolado vai para reprocessamento conforme descrito acima; ao chegar aos tanques de estocagem a solução apresenta uma coloração mais clara e durante o carregamento a solução passa por filtros de poliéster para ser enviada a outras empresas como matéria prima.
