MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617072235 A) filed by Basf Se on June 10, 2026, for Discontinuously Operated Desublimer Having At Least Three Baffle Plates.
Inventors include Grackiewicz, Gregor; Scharf, Florian; and Uppenkamp, Sebastian Tobias Number.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The invention relates to a discontinuously operated desublimer (1) for removing at least one gas component to be desublimed from a gas mixture flow, the desublimer comprising: a housing wall (7); an inlet (2) on the housing wall (7) for feeding the gas mixture flow into the desublimer (1); an outlet (6) on the housing wall (7) for discharging the treated gas mixture flow from the desublimer (1); a desublimation zone (4) having temperature-controllable flow channel walls, the flow channel walls being temperature-controllable 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) situated between the inlet (2) and the desublimation zone (4); and a gas outlet space situated (5) between the outlet (6) and the desublimation zone (4). According to the invention, at least a first guide plate (8a), a second guide plate (8b) and a third guide plate (8c) are arranged in the gas inlet distributor space (3) in order to evenly distribute the gas mixture flow through the flow channels formed by the flow channel walls of the desublimation zone (4), and at least three guide plates (8a, 8b, 8c) each have a spacing (HLB, a-b, HLB, b-c) to the guide plate or guide plates adjacent thereto in the range from 0.01 to 0.9 * D, preferably in the range from 0.10 to 0.50 * D, where D corresponds to the equivalent diameter of a circle of equal area to the inlet area (9). The invention also relates to a method for operating a desublimer (1) according to the invention.
