    Abstract: The present disclosure relates to methods and systems for monitoring for gel formation in the production of a polyamide product. In one embodiment, the present invention provides a method that can include directing a partially polymerized polyamide mixture through a flasher feed pump, a finisher pump, and a transfer line pump. The method can include switching the flasher feed pump, the finisher pump, and the transfer line pump from a first operating mode to a second operating mode. The method can include activating a gel time control unit and can be activated to estimate a gelation time for at least one of a flasher, a finisher, and a transfer line. The method can include switching a reactor of the polyamide synthesis system from the first operating mode to the second mode.

    Abstract: The present invention relates to methods, systems, and apparatus for synthesizing a polyamide and including multiple back-ends. The method can be a method of synthesizing a polyamide, including evaporating a mixture comprising an oligomer formed from a linear dicarboxylic acid and a linear diamine sufficient to remove at least some water from the mixture, to provide a pre-finished mixture. The method can include splitting the pre-finished mixture into at least a first pre-finished mixture and a second pre-finished mixture. The method can include finishing the first pre-finished mixture in a first finisher, to provide a first finished mixture comprising a first polyamide. The method can include finishing the second pre-finished mixture in a second finisher, to provide a second finished mixture comprising a second polyamide.

    Abstract: A finisher assembly includes a finisher agitator having a spiral ribbon. The spiral ribbon includes an exterior edge that wipes a polymer fluid from an inner vessel wall of a finisher vessel of the assembly. One or more mixing struts are coupled along the spiral ribbon. An agitator ring is coupled with one or more of the spiral ribbon or the one or more mixing struts. The agitator ring and the one or more struts are recessed from the inner vessel wall compared to the exterior edge of the of spiral ribbon in close proximity to the inner vessel wall. When the agitator is rotated the one or more mixing struts and the agitator ring mix the polymer fluid without disturbing gel along the inner vessel wall or the mixing struts according to the recessing of the agitator ring and the mixings struts from the inner vessel wall.

    Abstract: A polymer finisher assembly having a finisher nozzle includes a vessel including an outlet orifice and an inlet orifice. The finisher nozzle extends through the inlet orifice of the vessel. The finisher nozzle includes an isometric barrel extending between a nozzle inlet port and a nozzle outlet port. A separator helix is within the isometric barrel. The separator helix separates a mixed flow of steam and polymer fluid and directs steam toward a barrel inner perimeter and directs the polymer fluid separated from the steam toward a helix axis and the nozzle outlet port. The isometric barrel and the separator helix cooperate to confine spattering of polymer fluid separated from steam to the melt pool and isolate an inner vessel wall of the vessel from spattering.
