摘要： A 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 (∝) 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. A method also is provided for installing the structured packing in an exchange column

摘要： A divided wall exchange column includes a dividing wall strengthened by stiffening members and/or a double wall design to better withstand pressure differentials and minimize temperature differentials. When a double wall is used, cost of manufacture and installation is minimized by reducing the manufacturing tolerances required while providing a design robust in construction, installation, and operation. When structured packing is used, the stiffening members, combined with positioning the layers of packing at preferred angles relative to the dividing wall, result in minimal interference with the heat and/or mass transfer process while minimizing the complexity of manufacture and construction of the packing. Further, by positioning the top layer of structured packing at other preferred angles relative to the dividing wall, a simplified liquid distributor design may be used in the divided wall exchange column while the layers below may still be orientated as described above with all the associated benefits.

摘要： A layer of mixed-resistance structured packing includes: a first structured packing having a first packing resistance; and a second structured packing generally horizontally adjacent the first structured packing, the second structured packing having a second packing resistance different than the first packing resistance. The layer of mixed-resistance 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. Use of the layer of mixed-resistance structured packing reduces HETP (height equivalent to a theoretical plate) in the exchange columns and processes. A method also is provided for assembling the layer of mixed-resistance structured packing in an exchange column.

摘要： The present invention relates to a boiling process in a downflow heat exchanger and the heat exchanger itself with liquid distribution enhancing features which improve performance and allow safe and efficient operation. Performance enhancing features include a partially flooded hardway distribution region with a liquid volume fraction greater than about 0.25 and preferably greater than 0.5, adjusting the heat transfer surface area to maintain a liquid film Reynolds number above 20 and, preferably, above 50 yet less than 1000, preferably less than 300, for at least 75% of the reboiler surface, and, optionally, intermediate feeding of liquid at various intervals along the length of the heat exchanger to obtain more uniform values of liquid film Reynolds numbers and intermediate redistribution.
