Abstract
A chemical vessel utilizing induction heating elements and useful for preparing polyamides, such as nylon. 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.
Claims30
A chemical vessel comprising:
- a chamber comprising an outer wall and an internal cavity;
- and two or more heating elements within the internal cavity of the chamber, the heating elements each comprising a susceptor and an induction coil optionally connected to a power source,
- wherein the heating elements are positioned as an array that comprises a circumferential channel and an axial channel between two or more of the heating elements about an axis of the chamber, which is a vertical axis or an axis corresponding to the predominant direction of flow through the vessel.
A process for preparing a polyamide polymer comprising:
- mixing a solution of polyamide precursors in a vessel comprising one, two, or more heating elements, each comprising a susceptor and an induction coil optionally connected to a power source;
- and
- heating the polyamide precursor via electromagnetic induction to provide the polyamide product.
