Abstract: Vapours and gases containing compds. which sublime from a reactor are fed into a desublimation zone which consists of a cooled cylindrical shell in which a bed of desublimed particles are held in turbulent motion by agitator with blades. If the angular velocity of the rotor is W and the i. radius of the shell R, the Froude number is defined as Rw2/g where g is the acceleration due to gravity. Fr. should be above 1, pref. 5-10. The gas flowsin at one side of the shell and out with the particles at the other. The agitator is heated. There is an annular space for collecting product at the end of the shell. There should be a clearance of 0.5-12mm between the edge of the blades and the shell.

Abstract: Flange connections having multi-layer apparatus or pipeline parts one below the other, in which corrosive and hot gases are manipulated, consist of an inner lining, which is composed of glass or quartz that is resistant to temperature changes and is surrounded by an external metal jacket, the intermediate space between the outer jacket and the lining being filled with a thermally insulating material. Arranged between the lining and the outer jacket, in the region of the ends of the lining, there are fire-resistant blocks, which surround the lining, are supporting, and do not touch over the complete area, the lining with the fire-resistant blocks terminating at at least one end in a manner which is not flush. The fire-resistant blocks surrounding the lining close at least largely in a flush manner with the outer jacket surrounding them, whose two ends merge into a flange connection.

Abstract: De-dusting of gases is carried out in an apparatus containing a granular-bed filter, the pourable granular filter medium flowing downward through the bed. The apparatus comprises a vessel of rectangular cross-section with a vertical side wall (4) extending from the top to the bottom. A partition (5), arranged parallel to the side wall (4), extends from the upper end of the vessel into the interior of the vessel. The remaining three side walls of the vessel extend - at least starting from a level corresponding to the lower end of the partition (5), taperingly downward to the outlet (9). The partition (5) is supported by the two walls adjacent to the vertical wall and forms, together with these and with the talus (7) of the filter medium, which arises at the lower end of the partition, a chamber (3) into which the inlet (2) for the gas to be purified opens. At the inlet (10) for the filter medium, located at the upper end of the partition, a further talus (12) of the filter medium forms, defining a collecting chamber (16), in which the outlet (17) for the purified gas is located.
