Abstract

A heatable distributor includes a vessel with an upstream portion and an adjacent downstream portion, the upstream portion includes a first lateral end with an inlet and a second lateral end connected with the downstream portion. the downstream portion includes a first lateral end and a second lateral end, the first lateral end connected with the second lateral end of the upstream portion, and the downstream portion includes a hollow double-plate assembly including an upper plate and a lower plate spaced apart so that a void chamber is defined therebetween. Each plate includes openings, each opening of the upper plate is surrounded by a wall extending through the void chamber and surrounding an opening of the lower plate to form channels being fluid-tightly separated from the hollow space and, the hollow space is connected with an inlet for a heat medium and with an outlet for the heat medium.

A heatable distributor for a devolatilization apparatus for devolatilizing a composition comprising a volatile component, the heatable distributor comprising:

at least one vessel with an upstream portion and an adjacent downstream portion, the upstream portion of the vessel comprises a first lateral end comprising an inlet and an opposite second lateral end being connected with the downstream portion, wherein the downstream portion of the vessel comprises a first lateral end and an opposite second lateral end with the first lateral end being connected with the second lateral end of the upstream portion, and the downstream portion of the vessel comprises a hollow double-plate assembly, the hollow double-plate assembly comprises an upper plate and a lower plate being arranged on top of each other, and spaced apart so that a void chamber is defined therebetween, each plate of the hollow double plate assembly comprising a plurality of openings, each opening of the plurality of openings of the upper plate is surrounded by a wall extending through the void chamber and surrounding an opening of the plurality of openings of the lower plate so as to form a plurality of channels being fluid-tightly separated from the hollow space being defined in the void chamber between the channels, the hollow space connected with an inlet for a heat medium and with an outlet for a heat medium, the at least one vessel is an at least substantial horizontal vessel, such that while installed in the devolatilization apparatus, its-a longitudinal axis of the at least one vessel extends at least substantial horizontal, such that the an angle between the longitudinal axis of the vessel and a horizontal direction is at most 20°, a peripheral area and the first lateral end of the upstream portion of the vessel are, except for the inlet, completely bordered by a wall, and the second lateral end of the downstream portion of the vessel is slanted with regard to the longitudinal axis.
