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.
