Filed:

Jan 4, 2002

Appl. No.:

10/039866

Inventors:

Stephen John Cook - Macungie PA
John Louis Griffiths - Pittsburgh PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

F25J 304

US Classification:

62640, 62925, 252372, 423210

Abstract:

A method for recovering krypton and xenon from air comprises (a) separating an air feed stream into oxygen-enriched and nitrogen-enriched product streams; (b) reacting the oxygen-rich product stream with a hydrocarbon feed in a synthesis gas generation process to yield a synthesis gas stream comprising hydrogen, carbon oxides, krypton, and xenon, which synthesis gas stream contains essentially no oxygen; (c) introducing the synthesis gas stream into a synthesis gas conversion process and converting the synthesis gas stream into a liquid synthesis product stream and an unreacted synthesis gas stream; (d) recycling at least a portion of the unreacted synthesis gas stream to the synthesis gas generation process; (e) reducing the pressure of the liquid synthesis product stream to yield a two-phase reduced-pressure product stream, and separating the two-phase reduced-pressure product stream into a final liquid synthesis product stream and a gas stream enriched in krypton and xenon; and (f) separating the gas stream enriched in krypton and xenon into a purge gas stream and a gas product stream further enriched in krypton and xenon.

Appl. No.:

/071481

Inventors:

Rakesh Agrawal - Emmaus PA

Stephen John Cook - Macungie PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

F25J 304

US Classification:

62643

Abstract:

A process is set forth for the cryogenic distillation of an air feed to produce at least two oxygen-rich gaseous streams having different oxygen purities. The process uses a mixing column system in addition to a distillation column system. A key to the process is that at least two oxygen-rich liquid streams having different oxygen purities are transferred from the distillation column system to the mixing column system in order to produce the oxygen-rich gaseous streams.

Assignee:

THE BANK OF NEW YORK MELLON - New York NY

International Classification:

G06Q 40/04

US Classification:

705 37

Abstract:

In one embodiment, a method for electronically trading shares of an exchange-traded fund over a network including one or more processors, the fund being a counterparty to one or more repurchasing parties in a repurchase agreement, includes receiving order data from one or more investors relating to a trade of shares of the fund. The method also includes matching the fund with the one or more repurchasing parties. The method additionally includes receiving securities data from the one or more repurchasing parties, and allocating the related securities to be used as collateral applied to the fund. The method additionally includes sending securities payment data for the securities to the one or more repurchasing parties. The method further includes receiving repurchase payment data from the one or more repurchasing parties to repurchase the securities used as collateral, and sending the securities data to the one or more repurchasing parties.
