Abstract: The present disclosure relates to systems and methods for recovering water from a condensation reaction of at least one carboxylic acid and at least one diamine to make polyamide. The method can include obtaining, from an evaporator, an aqueous mixture comprising a partially polymerized polyamide and at least one of a carboxylic acid and diamine; passing the aqueous mixture through a tubular reactor comprising subjecting the aqueous mixture to a temperature and pressure sufficient to further polymerize the partially polymerized polyamide by condensation of the carboxylic acid and diamine, thereby producing water having a substantially gaseous phase; passing the water having a substantially gaseous phase into a rectification column thereby removing one or more of a diamine, a carboxylic acid and polyamide to provide purified water having a substantially gaseous phase; and condensing the purified water having a substantially gaseous phase into purified water having a substantially liquid phase. The system can include, among other things, a tubular reactor, a rectification column, a condensation assembly, and a conduit network.

Abstract: The present disclosure relates to systems and methods for manufacturing a polyamide. The method can include obtaining, from a reservoir, an aqueous solution comprising a dicarboxylic acid, a diamine, and water having a substantially liquid phase; concentrating the aqueous solution including transforming a portion of the water having a substantially liquid phase to water having a substantially gaseous phase; condensing the water having a substantially gaseous phase into condensed water having a substantially liquid phase; removing at least one impurity from at least one of the condensed water having a substantially liquid phase and the water having a substantially gaseous phase to produce cleaned water having a substantially liquid phase; and reusing the cleaned water having a substantially liquid phase. The system can include, among other things, a reservoir; an evaporator assembly, in fluid communication with the reservoir; a condensation assembly, in fluid communication with the evaporator assembly; a collection assembly; and a conduit network.
