    Abstract: PCT No. PCT/AU93/00340 Sec. 371 Date Mar. 16, 1994 Sec. 102(e) Date Mar. 16, 1994 PCT Filed Jul. 9, 1993 PCT Pub. No. WO94/01210 PCT Pub. Date Jan. 20, 1994.A reactor for introducing gas into a fluid comprises a mixing tank (12, 43) for the fluid and a partition means (13,45) for dividing the tank into at least two chambers (21, 89) and (23, 91). The reactor further comprises a first pump means (14, 47) located in one of the chambers for circulating the fluid downwards in one chamber and then upward in the other chamber and an aerator assembly (29, 49) for aerating a sidestream of the fluid and introducing the aerated fluid into the tank for mixing the aerated fluid with the circulating fluid in the tank. The aerator assembly comprises a bank of venturi aerators (38, 57) each having an aerator inlet; an aerator outlet; and a constriction intermediate the aerator inlet and the aerator outlet for creating a region of reduced pressure in the fluid, the constriction being elongate in a section transverse to the direction of flow of the fluid through the constriction; and a means for introducing the gas into the constriction to aerate the fluid.

Date Jan. 6, 1994A method of treating inorganic solid waste in a bath of molten metal contained in a vessel (3) which has a space above the bath and a waste gas outlet (11) is disclosed. The method comprises injecting waste into the bath to form a primary reaction zone (13) in which there are reactions between the waste and the bath or in which the waste undergoes a change of phase to convert the waste into more readily recoverable or disposable products. The method further comprises injecting oxygen-containing gas towards the surface of the bath to form a secondary reaction zone (17) in a section above the bath through which oxidisable products released from the primary reaction zone (13) flow to reach the waste gas outlet (11) in the vessel (3) and in which the oxidisable products are oxidised and the heat released by such oxidation is transferred into the bath.

    Abstract: 2103675 9310862 PCTABS00022 A method of destroying organic waste in a bath of molten metal and slag contained in a vessel (3) is disclosed. The method comprises injecting organic waste into the bath to form a primary reaction zone (13) in which the organic waste is thermally cracked and the products of the thermal cracking which are not absorbed into the bath are released into the space above the surface of the bath. The method further comprises injecting an oxygen-containing gas towards the surface of the bath to form a secondary reaction zone (17) in the space above the surface of the bath in which the oxidizable materials in the products from the primary reaction zone (13) are completely oxidized and the heat released by such oxidation is transferred to the bath. In order to facilitate efficient heat transfer from the secondary reaction zone (13) to the bath, the method further comprises injecting an inert or other suitable gas into the bath to cause molten metal and slag to be ejected upwardly from the bath into the secondary reaction zone (17).
