Abstract
"PROCESSO PARA RECUPERAR áCIDO TEREFTáLICO BRUTO (CTA)". A presente invenção refere-se a um processo para a preparação de ácido tereftálico bruto que compreende primeiro introduzir uma pasta contendo ácido tereftálico cristalizado com impurezas em um licor mão de ácido carboxílico alifático em um filtro rotativo compreendendo uma carcaça e um tambor rotativo, sendo que o tambor rotativo é submetido a um diferencial de pressão uniforme ao longo do tambor inteiro, e dentro do tambor a uma pressão aproximadamente igual à pressão atmosférica ou maior, sendo então filtrada a dita pasta; e finalmente é recolhida pelo menos alguma da porção sólida. Outros aspectos da invenção incluem adicionar continuamente a pasta original ao filtro rotativo e lavar a porção sólida com ácido carboxílico alifático adicional, água ou uma combinação de ambos. A porção sólida pode então ser transferida para um tanque de reempastamento que está à mesma pressão que a pressão no ponto onde a porção sólida foi recolhida. A presente invenção também se refere a um processo para a preparação de ácido tereftálico bruto que compreende primeiramente introduzir uma pasta contendo ácido tereftálico cristalizado com impurezas em um licor mãe de ácido carboxílico alifático em um filtro rotativo compreendendo uma carcaça e um tambor rotativo, sendo que o tambor rotativo é submetido a um diferencial de pressão uniforme ao longo do tambor inteiro, sendo a dita pasta em seguida filtrada, sendo a porção sólida lavada com água; e sendo finalmente recolhida pelo menos alguma da dita porção sólida. Outros aspectos da invenção incluem adicionar continuamente a pasta original ao filtro rotativo e lavá-la adicionalmente com o licor mãe de ácido carboxílico alifático. O interior do tambor pode estar a uma pressão menor que, maior que, ou igual à pressão atmosférica. A porção sólida pode então ser transferida para um tanque de reempastamento que esteja à mesma pressão que a pressão no ponto onde a porção sólida foi recolhida.
