    Abstract: A valve includes a valve body and a bolt. The valve body has an input port and an output channel coupled by a primary passageway. The valve body has a bolt bore aligned to intersect the primary passageway. The valve body has a divert port disposed at an end of the bolt bore. The valve body has an intersection at the output channel and the primary passageway including a gradual transition. The bolt has a first end and a second end aligned on a longitudinal axis. The bolt has a through passageway aligned transverse to the longitudinal axis and has a divert passageway disposed between a side aperture and the first end. The bolt is configured for slidable engagement with the bolt bore.

    Abstract: A system is configured for continuous polyamide synthesis. The system includes a vent condenser and a vacuum pump. The vent condenser is coupled to a polymerization finisher. The vent condenser has a liquid reservoir and a vent discharge port above a level of the liquid reservoir. The vacuum pump is coupled to the vent discharge port by an intake line. The vacuum pump has an output port and a rotary shaft. A gaseous mixture proximate the vent discharge port is removed at a rate determined by a speed of the rotary shaft. The vacuum pump is configured to have a liquid ring seal.

    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.
