US Patent:

6562896, May 13, 2003

Filed:

Dec 9, 1999

Appl. No.:

09/457559

Inventors:

Bruce A. Lysek - Cantonment FL
Russell F. Dunn - Cantonment FL
Cary J. Kostakes - Hoffman Estates IL

Assignee:

Solutia Inc. - St. Louis MO

International Classification:

C08L 7700

US Classification:

524538, 525424

Abstract:

A polyamide composition including (a) at least one polyamide other than nylon 2,2, or a copolymer of at least two polyamide repeating units, neither of which is nylon 2,2, (b) melamine cyanurate, and (c) a nucleating agent such as nylon 2,2 in an amount effective to cause nucleation of the polyamide of (a), has good flame retarding properties and relatively short set-up times in molding processes.

Appl. No.:

12/221878

Inventors:

Anthony B. Davis - Calvert City KY, US
Thomas H. Yohe - Oak Forest IL, US
Russell F. Dunn - Cantonment FL, US

Assignee:

Westlake Vinyl Corporation - Houston TX

International Classification:

C25B 1/16
C25B 9/00

US Classification:

205510, 205512, 205516, 204274, 2042751

Abstract:

A method for concentrating an aqueous caustic alkali produced by a membrane cell process by using a single or multiple effect evaporator system in which the vapor flows in a counter direction to the aqueous caustic alkali flow and the heat recovered from the catholyte circulation line is used as part of the concentration process. In one embodiment, a catholyte heat recovery heat exchanger and evaporation chamber are located after the last effect of a multiple effect evaporator system. In another embodiment, the catholyte heat recovery heat exchanger and evaporation chamber are located prior to the single or multiple effect evaporator system. In yet another embodiment, the catholyte heat recovery process is used in conjunction with additional heat exchanger processes to further concentrate the final product as desired.

Abstract:

A method for concentrating an aqueous caustic alkali produced by a membrane cell process by using a single or multiple effect evaporator system in which the vapor flows in a counter direction to the aqueous caustic alkali flow and the heat recovered from the catholyte circulation line is used as part of the concentration process. In one embodiment, a catholyte heat recovery heat exchanger and flash evaporation chamber are located after the last effect of a multiple effect evaporator system. In another embodiment, the catholyte heat recovery heat exchanger and flash evaporation chamber are located prior to the single or multiple effect evaporator system. In yet another embodiment, the catholyte heat recovery process is used in conjunction with additional heat exchanger processes to further concentrate the final product as desired.
