Abstract

Patente de Invenção: <B>"SISTEMA DE CONTROLE PARA PROCESSO DE POLIAMIDAçãO CONTìNUA"<D>. Um sistema de poliamidação e um sistema de controle para produzir uma poliamida a partir de monómero ácido dicarboxílico fundido e de monómero diamina fundido. O sistema de controle de poliamidação mede a razão molar do monómero ácido dicarboxílico fundido e do monómero diamina fundido com uma mistura parcialmente polimerizada. Um algoritmo de controle de alimentação adiantada é empregado dentro do sistema de controle para determinar a extensão à qual a razão dos reagentes iniciais deve ser alterada antes da mistura de forma a produzir a poliamida resultante tendo uma razão molar estequiometricamente equilibrada.Invention Patent: <B> "CONTROL SYSTEM FOR CONTINUOUS POLYAMIDATION PROCESS" <D>. A polyamidation system and a control system to produce a polyamide from fused dicarboxylic acid monomer and fused diamine monomer. The polyamidation control system measures the molar ratio of the fused dicarboxylic acid monomer and the fused diamine monomer with a partially polymerized mixture. An early feed control algorithm is employed within the control system to determine the extent to which the ratio of the initial reagents must be changed prior to mixing in order to produce the resulting polyamide having a stoichiometrically balanced molar ratio.
