    Abstract: Integrated primary and secondary cyclone assembly includes a secondary cyclone having an outlet tube extending therefrom and a primary cyclone operatively coupled with the secondary cyclone. The outlet tube has a cross dimension and length and is configured to be secured to a pressure vessel closure head to support the secondary cyclone therefrom. The primary cyclone has a tubular support member extending therefrom. The tubular support member is aligned substantially parallel with and has a length similar to the outlet tube of the secondary cyclone and is configured to be joined to the pressure vessel closure head to support the primary cyclone therefrom.

    Abstract: A method of making acetic anhydride or a mixture of acetic anhydride and acetic acid comprising: (a) catalytically reacting a feedstock containing methyl acetate and/or dimethyl ether with carbon monoxide in the presence of a homogeneous rhodium catalyst and methyl iodide in a reactor vessel which contains a substantially anhydrous liquid reaction mixture including acetic acid, acetic anhydride, methyl acetate and/or dimethyl ether, methyl iodide and the homogeneous catalyst, the reactor vessel being operated at a reactor pressure; (b) withdrawing reaction mixture from the reaction vessel and feeding the withdrawn reaction mixture along with additional carbon monoxide to a pre-flasher/post reactor vessel operated at a reduced pressure below the reactor vessel pressure; (c) venting light ends in the pre-flasher vessel and concurrently consuming methyl acetate and/or dimethyl ether in the pre-flasher/post reactor vessel to produce a pre-flash mixture which is enriched in acetic anhydride and diminished in methyl iodide and methyl acetate and/or dimethyl ether as compared with the reaction mixture; (d) withdrawing the pre-flash reaction mixture from the pre-flasher/post reactor vessel and feeding the pre-flash mixture to a flash vessel; and (e) flashing a crude product stream from the mixture in a flash vessel operated at a pressure substantially below the pressure of the pre-flasher/post reactor vessel.

    Abstract: A process for high temperature hydrolysis of halosilanes and halides with the steps of: providing a bed of fluidized particulate material heated to at least 300° C., injecting steam and an excess of reactants into the reactor, removing solid waste from a bottom outlet, removing the effluent gases through a solids removal device such as a cyclone, condensing and separating some of the unreacted waste from the effluent gas in a distillation column and sending the effluent gases containing hydrogen and hydrogen chloride to a compressor. In a preferred embodiment the reactants contain at least one water reactive halide, selected from the group halosilane, organohalosilane, aluminum halide, titanium halide, boron halide, manganese halide, copper halide, iron halide, chromium halide, nickel halide, indium halide, gallium halide and phosphorus halide and where the halide content is selected from chlorine, bromine and iodine.
