Abstract

''PROCESSOS DE DESIDRATAçãO E SEPARAçãO GERENCIADOS TERMICAMENTE PARA RECUPERAçãO DE PRODUTOS áCIDOS'' São descritos processos preferidos de separação de produtos químicos desejados de outros compostos em solução utilizando-se cromatografia gerenciada termicamente sobre adsorventes sólidos. Os processos preferidos envolvem princípios que são auxiliados por variação da temperatura de operação em fases de separação e eluição. Também são descritos para tratamento de ácidos aquosos para desidratar e recuperar os ácidos em um solvente orgânicos tal como um álcool.
