Title: Removal of chlorine and phosgene - from waste-gases in production of aluminium chloride from oxide
IPC: C01F7/58
Filed: 1971-04-01
Abstract: The waste gases formed during the prepn. of AlCl3 by reacting Al2O3 with Cl2 and/or phosgene in the presence of CO, are purified before discharge into the atmos. by passing them through solid Al-lumps or Al-grit at 300-600 degrees C.

The Cl2 and/or COCl2 content is removed in an exothermic reaction which converts practically all the Al to AlCl3, with no side reactions. Besides being an efficient gas purification process, a further quantity of the desired end product is thus formed.

Title: Residue separation from wet zinc or copper extraction - by flocculation and archimides screw washing
Inventor: DIEHL ERWIN DR
IPC: C02F1/52
Filed: 1971-12-29
Abstract: Separation and washing of slimy residues, which are impossible to filter from the acid Zn and/or Cu salt solns. from wet extraction of Zn and Cu contg. scrap, which residues have nearly the same density as the metal salt solns. is carried out by digesting of the residue contg. solns. in a flocculating chamber using excess flocculating agents, after which the residue particles are freed from H arising from the after reaction between excess acid and metallic fines and then thickened in a quiescent zone into a lumpy agglomerate, which is passed through an inclined Archimedes screw conveyor where it is counter current wise washed such that at first dispersion takes place of the flakes in the adhering salt soln. followed by renewed flocculation to large surface area porous flakes. These are then exposed to the washing soln. such that the latter does not stir up the flakes thus obtaining a phase boundary, which must be below the upper helix edge. A partial return flow of the residue is effected through the adjustable gap between screw and pipe surrounding it, the washed residue being introduced into a collecting vessel, in which it displaces an equal vol, washing liq. following which it is thickened to a lumpy consistency and drawn off.
