Abstract

Forbedret pdlyamideringssystém og reguleringssystem for fremstillingl av et polyamid fra smeltet dikarboksylsyremonomer og smeltet diaminmonomer. Poly- amiderings-reguleringssystemet måler molforholdet av den smeltede dikarboksyl- ~syremonomeren'og den smeltede diaminmonomeren med en delvis polymerisert blanding. En fremovermatingsreguleringsalogaritme anvendes i reguleringssyste- met for å bestemme graden som forholdet av utgangsreaktantene må endres før blanding for å kunne produsere det resulterende polyamidet med et støkiometrisk balansert molforhold.Improved pdlyamidation system and control system for producing a polyamide from molten dicarboxylic acid monomer and molten diamine monomer. The polyamide control system measures the molar ratio of the molten dicarboxylic acid monomer and the molten diamine monomer with a partially polymerized mixture. A forward feed control algorithm is used in the control system to determine the degree to which the ratio of the starting reactants must be changed before mixing in order to produce the resulting polyamide with a stoichiometric balanced mole ratio.
