    摘要: A submicron filter assembly (24) is added to an exhaust gas controlled destruction and oxidation unit (10). Controlled destruction and oxidation unit (10) treats exhaust gas from at least one semiconductor wafer fabricating reactor. The submicron filter (24) filters submicron particles out of the treated exhaust gas to prevent visible plumes from forming in wafer fab exhaust systems (stacks). The controlled destruction and oxidation unit (10) and submicron filter assembly (24) are ideally suited for use at the point of generation of the exhaust gases. In one embodiment of the invention, the submicron filter assembly comprises an electrostatic filter (26). The electrostatic filter (26) includes a positively charged first grid (28) and a grounded second grid (30). The second grid may include a mist screen for removing particulate build-up. In another embodiment of the invention, the submicron filter assembly (36) comprises a mist eliminator (38) and a HEPA filter (40).

    摘要: A filter segment disc of a segment filter comprises a support and drainage plate with slots radiating from the filter hub toward the filter edge. The slots are preferably of arcuate plan form and configured to provide a substantially uniform fluid flow over the filtering medium of the filter segment, reduce residence time of filtrate in the filter, eliminate dead spots in the flow, and facilitate cleaning of permanent filters. A filter support spacer may be provided adjacent the filtering surface to aid in support and positive spacing of the disc in a filter stack of which the disc may be an element.

    摘要: An improved process for the liquefaction of solid carbonaceous materials wherein a solvent or diluent derived from the solid carbonaceous material being liquefied is used to form a slurry of the solid carbonaceous material and wherein the solvent or diluent comprises from about 65 to about 85 wt. % hydroaromatic components. The solvent is prepared by first separating a solvent or diluent distillate fraction from the liquefaction product, subjecting this distillate fraction to hydrogenation and then extracting the naphthenic components from the hydrogenated product. The extracted naphthenic components are then dehydrogenated and hydrotreated to produce additional hydroaromatic components. These components are combined with the solvent or diluent distillate fraction. The solvent may also contain hydroaromatic constituents prepared by extracting naphthenic components from a heavy naphtha, dehydrogenating the same and then hydrotreating the dehydrogenated product. When the amount of solvent produced in this manner exceeds that required for steady state operation of the liquefaction process a portion of the solvent or diluent distillated fraction will be withdrawn as product.
