Abstract
processo para aperfeiçoar taxa de filtração de purga de ácido tereftálico. o processo se refere ao aperfeiçoamento da taxa de filtração de purga de ácido tereftálico através do controle do % de água na suspensão de alimentação do filtro e à recuperação de um catalisador metálico a partir de uma corrente de purga do oxidante produzida na síntese do ácido carboxílico, de um modo típico ácido tereftálico, ao mesmo tempo em que é utilizada a filtração por pressão.
