Abstract: Drying the effluent from the trinitrotoluene (TNT) purification process, known as red water, is described that uses spray drying in an efficient, improved, and safe manner. The characteristics of the obtained powder, the use thereof, and a packaged product containing said powder are further described. The proposed technique provides the use of lower temperatures at liquid incineration (<300° C. compared to 1000° C.), and also the fact that the main target material is not broken down, thereby not generating toxic fumes, and enabling the dry powder to be used for other applications.

Abstract: The present invention relates to a rocket launching module comprising a base frame (1) comprising at least one rail (2a); a sliding table (3) configured to slide substantially vertically on said rail (2a) when driven by at least one electric linear actuator (11), and a targeting device (4) comprising a turntable (5) on which a pivotable body (6) is mounted, supporting a rocket support portion (7). The sliding table (3) comprises a platform (8) configured to receive the turntable (5) of the targeting device (4).

Abstract: The invention relates to a method for assembling at least one radial adsorber including at least two concentric perforated grids, an upper base, a lower base, and a cylindrical collar with the same axis as said grids, characterised in that said perforated grids are assembled concentrically on the horizontal plane.

Abstract: This column, of the type having a cross-undulating lining, includes means for returning liquid to the vicinity of the edges of the lining and liquid and gas distribution means which contribute to decrease substantially the height of the column. Application to plants for separating gases from air.

Abstract: This distributor comprises: a peripheral crown; a series of vertical partitions fixedly mounted on the crown at both ends thereof and extending parallel to one another; sealingly closing means bounding, between the vertical partitions, alternate spaces for collecting gas and liquid; means enabling the upward evacuation of the gas contained in the spaces for collecting gas; and a perforated bottom disposed at the base of each liquid collecting space and sealingly connected to the or each adjacent vertical partition and to the crown. Application to air distillation columns.
