摘要: 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.

摘要: A furnace configuration is disclosed in which the furnace is inductively heated by external insulated coils and a susceptor is placed within the charge of reactants away from the outer surfaces of the charge. Consequently, heat is transferred to the charge and the process approaches completion before the insulation is subjected to high temperatures.

摘要: A method and apparatus of heating or cooling a charge of a solid material are disclosed. The method includes the steps of supplying a charge of the material to form a packed bed of solids in a process vessel having one or more passageways through which a heat transfer fluid can flow, passing a heat transfer fluid through the one or more passageways and supplying a working fluid to said vessel. The method is characterized by circulating the working fluid through the bed, the circulation step including removing at least part of the working fluid from one or more sections of the vessel and then returning the working fluid to other sections of the vessel.

摘要: 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 toward 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 second 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).
