    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: A reaction zone is provided comprising a plurality of oxygen clean up zones and a plurality of oxidation zones. A first stream is introduced to oxidation clean up zones comprising liquid cyclohexane, and optionally a cyclohexane oxidation catalyst. In addition, an oxygen containing gas is introduced into the oxidation zones. Next, the first stream is passed downwardly from the oxygen clean up zones to the oxidation zones, while cross-currently passing the oxygen containing gas upwardly from the oxidation zones to the oxygen clean up zones. The oxygen containing gas is introduced directly into the first stream as it travels through the oxidation zones, and the reaction between the first stream and the oxygen containing gas produces a product mixture. Finally, a product mixture is withdrawn from the oxidation zones that comprises CHHP, cyclohexanone and cyclohexanol.
