Intellectual Property India Publishes Patent Application for Discontinuously Operated Desublimer Having At Least One Perforated Plate

MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617056700 A) filed by Basf Se on May 04, 2026, for Discontinuously Operated Desublimer Having At Least One Perforated Plate.

Inventors include Noll, Andreas; Uppenkamp, Sebastian Tobias; Pazicky, Marek; and Scharf, Florian.

The application for the patent was published on June 05, 2026, under issue no. 23/2026.

Abstract: The invention relates to a discontinuously operated desublimer (1) for removal of at least one gas component to be desublimed from a gas mixture flow, comprising a housing wall (7), an inlet (2) on the housing wall (7) to supply the gas mixture flow to the desublimer (1), an outlet (6) on the housing wall (7) for removing the treated gas mixture flow from the desublimer (1), a desublimation zone (4) having temperature-controllable flow channel walls, wherein the temperature of the flow channel walls is adjustable such that, during a loading process, the at least one gas component to be desublimed is desublimed on the flow channel walls, and such that, during a subsequent melting process, the at least one gas component desublimed in the loading process melts on the flow channel walls, a gas inlet distributor space (3) between the inlet (2) and the desublimation zone (4), and a gas outlet space (5) between the outlet (6) and the desublimation zone (4). According to the invention, at least one first perforated plate (8) disposed in the gas inlet distributor space (3) for uniform distribution of the gas mixture flow through the flow channels that arise from the flow channel walls of the desublimation zone (4) has a geometric centroid having a distance (AT) from the desublimation zone (4) in the range from 0 to Amax, preferably in the range from 0 to 0.5 * Amax and more preferably in the range from 0.03 to 0.3 * Amax, where Amax corresponds to the distance between the inlet area (9) of the inlet (2) and the desublimation zone (4), and where the at least one first perforated plate has a porosity in the range from 5% to 50%, preferably 10% to 30%, more preferably 10% to 20%. The invention further provides a method of operating a desublimer (1) of the invention.
