Abstract

"MéTODO DE TRATAMENTO DE APARELHO DE DESTILAçãO E PROCESSOS DE FABRICO DE áCIDO CARBOXìLICO AROMáTICO E DE áCIDO TEREFTáLICO". São revelados um método e uma composição solvente capazes de remover depósitos de óxido de ferro da superfície de componentes de titânio sem danificar substancialmente o componente de titânio subadjacente. Os depósitos de óxido de ferro podem ser removidos da superfície de um componente de titânio fazendo contactar o componente de titânio com a composição solvente da invenção. A composição solvente pode, então, ser removida do contato com o componente de titânio para obter urna composição solvente reciclável que é reciclada em contato repetido com o componente de titânio. A composição solvente compreende uma mistura aquosa de um ácido orgânico e um ácido hidrohaleto.
