    摘要： It is an object of the present invention to provide, for the case of continuously producing aromatic carbonates containing a diaryl carbonate as a main product by taking an alkyl aryl carbonate as a starting material, which is obtainable through a transesterification reaction between a dialkyl carbonate and an aromatic monohydroxy compound, using a continuous multi-stage distillation column in which a catalyst is present, and continuously feeding the starting material into the continuous multi-stage distillation column, a specific process that enables the diaryl carbonate to be produced with high selectivity and high productivity stably for a prolonged period of time on an industrial scale of not less than 1 ton per hour. Although there have been various proposals regarding processes for the production of aromatic carbonates by means of a reactive distillation method, these have all been on a small scale and short operating time laboratory level, and there have been no disclosures whatsoever on a specific process or apparatus enabling mass production on an industrial scale. According to the present invention, there is provided a specified continuous multi-stage distillation column, and there is also provided a specific process that enables a diaryl carbonate to be produced with high selectivity and high productivity stably for a prolonged period of time on an industrial scale of not less than 1 ton per hour from an alkyl aryl carbonate.

    摘要： A method of installing a structured packing in an exchange column, the structured packing having a surface area density in the range of about 500 m2/m3 to about 675 m2/m3 includes a plurality of corrugated plates disposed in vertically parallel relation. Each plate has at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate. The apertures have an equivalent diameter of less than about 4 millimeters but greater than about 2 millimeters. The corrugations have a corrugation angle (&agr;) relative to horizontal in the range of about 40° to about 60°. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle (&bgr;) defined by two sides of the corrugation in the range of about 90° to about 100°. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation.

    摘要： Apparatus for circulating a fluid, for example a liquid or a gas, from a first end to a second end is disclosed. The apparatus comprises: a tube of a flexible material divided by dividing walls of a flexible material into an array of compartments or cells running the length of the tube, the compartments being arranged in rows and columns so that the tube divided by dividing walls has a honeycomb structure, with a first end of the tube on a base and a second end of the tube above the first end of the tube; first flow means and second flow means a fluid inlet into the first row of compartments; and a fluid outlet from the last row of compartments; so that fluid introduced through the fluid inlet flows either up or down the compartments in the first row, through the first or second flow means between the first and second rows, and then down or up the compartments in the second row, through the second or first flow means between the second and third rows, and so on until the fluid reaches the fluid outlet. The apparatus may be used for the treatment of waste water.

    摘要： A catalytic distillation packing that has continuous smooth channels over its entire length is used to change out catalyst in a catalyst distillation arrangement without replacement of packing units and long turnaround times. The long, continuous channels are formed from perforated, corrugated plates that have a sufficient thickness to maintain the geometry of the channels and permit free catalyst flow for catalyst change out. The thickness of the plates also eliminates the need for complicated bracing and attachment arrangements that adds to the expense of the packing arrangement and can obstruct the movement of catalyst therethrough. The long, continuous channels are used with an inlet arrangement that provides ready adjustment of the number of channels that are filled with catalyst and channels that are free of catalyst. It is also possible in this arrangement to operate with a channel arrangement wherein all channels are filled with catalyst.
