Abstract
"MéTODO DE CONTROLE DE CONCENTRAçãO DE SOLUçãO EM LINHA DE LIMPEZA DE TIRAS". A presente invenção refere-se a um sistema de controle automático que é proporcionado para concentração de ácido em uma linha de limpeza de tira de alumínio em que uma tira de alumínio está em contato com uma solução ácida durante passagem através de um banho de limpeza com ácido e a concentração do ácido no banho é ajustada pela adição de ácido concentrado ou água ao banho. Uma sonda de condutividade proporciona um sinal para a concentração de ácido livre do banho e um titulador de processo em linha, periodicamente, proporciona um segundo sinal indicativo da concentração de ácido livre real e da concentração de ácido total. Esses primeiro e segundo sinais são usados para obter um valor corrigido para concentração de ácido livre. A concentração de ácido do banho é, então, ajustada, conforme requerido, baseado no valor corrigido da condutividade específica.
