Oxygen Separator Designed To Be Integrated With A Gas Turbine And Method Of Separating Oxygen
View pageUS Patent:
6360524, Mar 26, 2002
Filed:
Jun 13, 2001
Appl. No.:
09/879113
Inventors:
Raymond Francis Drnevich - Clarence Center NY
Minish Mahendra Shah - East Amherst NY

Christian Friedrich Gottzmann - Clarence NY
Assignee:
Praxair Technology, Inc. - Danbury CT
International Classification:
F02C 606
US Classification:
60 3902, 60 3907, 60722, 96 4
Abstract:
An oxygen separator and method for separating oxygen from a heated oxygen containing gas that employs oxygen-selective ceramic membranes of elongated, tubular configuration within a duct for separation of oxygen from a heated gas. The duct can be attached between the exhaust of a gas turbine and a power generator driven by the exhaust or can be connected to one or more burners of a gas turbine. Supplementary compressed feed air may be added at a flow rate at least equal to that of the permeated oxygen for cooling and flow balancing purposes. A purge stream can also be introduced. Additionally, combustor tubes fabricated from an oxygen-selective ceramic membrane material may also be provided to produce combustion products that in turn can be used as a purge for downstream oxygen-selective ceramic membranes.
Cryogenic Rectification System For Producing High Purity Oxygen

6460373, Oct 8, 2002
Filed:
Dec 4, 2001
Appl. No.:
10/000318
Inventors:
Bayram Arman - Grand Island NY
Minish Mahendra Shah - East Amherst NY
Minish Mahendra Shah - East Amherst NY
Assignee:
Praxair Technology, Inc. - Danbury CT
International Classification:
F25J 300
US Classification:
62652, 62654
Abstract:
A cryogenic rectification system comprising three columns wherein high purity oxygen is produced in the third column which is fed from at least one of the first and second columns, which do not share a common condenser/reboiler, and reboiled using feed air or first column top vapor.
Three Column Cryogenic Air Separation System With Dual Pressure Air Feeds
View pageUS Patent:
6536234, Mar 25, 2003
Filed:
Feb 5, 2002
Appl. No.:
10/062672
Inventors:
Minish Mahendra Shah - East Amherst NY
Assignee:
Praxair Technology, Inc. - Danbury CT
International Classification:
F25J 300
US Classification:
62646, 62647, 62900
Abstract:
A three column cryogenic rectification system for producing at least one of oxygen and nitrogen employing a medium pressure column which is operating at a pressure between the operating pressures of the higher and lower pressure columns, and which receives an air feed which is at a lower pressure than the air feed to the higher pressure column. The medium pressure column processes oxygen-enriched liquid from the higher pressure column and is reboiled by a fluid taken from below the top of the higher pressure column.
Cryogenic Rectification System For Producing Low Purity Oxygen Using Shelf Vapor Turboexpansion

6622520, Sep 23, 2003
Filed:
Dec 11, 2002
Appl. No.:
10/316116
Inventors:
Neil Mark Prosser - Lockport NY

Minish Mahendra Shah - East Amherst NY
Assignee:
Praxair Technology, Inc. - Danbury CT
International Classification:
F25J 304
US Classification:
62646, 62900
Abstract:
A cryogenic rectification system for producing low purity oxygen from an auxiliary column to a double column system and which can also effectively produce nitrogen gas product and/or one or more liquid products wherein the lower pressure column of the double column system is reboiled in part by turboexpanded shelf vapor which is condensed in an intermediate reboiler and preferably subcooled prior to passage into the lower pressure column.
Oxygen Separation Method Using A Ceramic Membrane Unit

International Classification:
B01D 5322
US Classification:
423219, 60 3912, 60772, 60774, 60801, 95 45, 95 54, 95288
Abstract:
A method of separating oxygen using a ceramic membrane unit having one or more ceramic membranes, preferably formed of a mixed conducting ceramic, for instance, a perovskite, capable of conducting both oxygen ions and electrons. Oxygen is separated within the ceramic membrane unit under impetus of compressing an incoming oxygen containing feed. The compressor used in the compression is powered by the work of expansion produced by expanding a process stream composed of at least a portion of the retentate produced in the ceramic membrane unit. Prior to expansion, the process stream is cooled to allow the use of less expensive materials in expanders used in the expansion. As a result, expansion of the process stream alone is insufficient to meet the power requirements involved in the compression. Interstage expansion with reheating is used to make up for the power deficit.
