The vessel can utilize an array of induction heating elements located inside a process chamber. Also described are a vessel, a heat exchanger, a process, and an apparatus useful for polyamide preparation.
Claims10
An apparatus for preparing a polyamide polymer, comprising:
- a vessel comprising a chamber containing two or more heating elements, the heating elements each comprising a susceptor and an induction coil optionally connected to a power source;
- an inlet for adding liquid polyamide precursors to the vessel;
- an outlet for removing water vapor from the vessel;
- and
- an outlet for removing the polyamide polymer from the vessel;
- wherein
- the heating elements are positioned in an array that provides one or more channels between the two or more heating elements through which liquid can flow, and
- the one or more channels comprise at least one channel that is circumferential about an axis of the chamber, and at least one channel that is parallel to the axis of the chamber;
- and the axis of the chamber is a vertical axis, or an axis corresponding to a predominant direction of liquid flow through the vessel.
