Abstract
Official abstract text for this publication.
Embodiments of the invention provide an apparatus or process for devolatilization of flowable materials (such as molten polymers with entrained or dissolved solvent or unreacted monomers or comonomers) using a plate heater having heating channels, the design or operation of which heating channels maintains the flowable material above its bubble point pressure during passage through a larger first zone and then induces flashing in, or downstream of, a smaller second zone of the heating channel. The apparatus enables a higher throughput per heating channel while achieving equivalent or better devolatilization, as compared to current devolatilization apparatus.
First claim
Opening claim text (preview).
We claim: 1. A process for the devolatilization of a flowable material comprising a liquid or flowable solid, and at least one entrained or dissolved volatile component, which process comprises passing that flowable material through a devolatilization apparatus while operating under devolatilization conditions, wherein said devolatilization apparatus comprises: (a) a pump for supplying a pressurized flowable material comprising at least one molten polymer and at least one dissolve…
