US Patent:

6357728, Mar 19, 2002

Filed:

Mar 15, 1999

Appl. No.:

09/270310

Inventors:

Swaminathan Sunder - Allentown PA
Herbert Charles Klotz - Allentown PA
George Amir Meski - Whitehall PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

B01F 304

US Classification:

2611122

Abstract:

A structured packing having a surface area density in the range of about 500 m /m to about 675 m /m 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 (â) relative to horizontal in the range of about 40Â to about 60Â. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle () defined by two sides of the corrugation in the range of about 90Â to about 100Â. 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.

Abstract:

A method for preparing a polyurethane foam which comprises reacting an organic polyisocyanate and a polyol in the presence of a blowing agent, a cell stabilizer and a catalyst composition consisting essentially of a compound of structure I ##STR1## wherein R is hydrogen, a C. sub. 1 -C. sub. 4 alkyl, C. sub. 6 -C. sub. 8 aryl, or C. sub. 7 -C. sub. 9 aralkyl group; and n is 1 to 8.
