METHODS AND SYSTEMS FOR THE RECOVERY OF WATER FROM A POLYAMIDE SYNTHESIS PROCESS

摘要

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.
