US Patent:

50733567, Dec 17, 1991

Filed:

Sep 20, 1990

Appl. No.:

7/586359

Inventors:

David E. Guro - Coopersburg PA
Ravi Kumar - Allentown PA
David M. Nicholas - New Tripoli PA
Gary S. Roth - Trexlertown PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

C01B 3102
C01B 2126
C01B 324
B01J 800

US Classification:

423415A

Abstract:

The present invention is an integrated process for the adsorptive recovery of a high purity carbon monoxide product from a gas mixture containing hydrogen, carbon monoxide, carbon dioxide, methane, and nitrogen, with the potential additional recovery of a hydrogen-rich stream and the recycle of the resulting gas mixture to a reformation reaction to produce the gas mixture with a more favorable carbon monoxide and hydrogen product slate. Separate carbon dioxide recovery can be performed. Hydrogen recovery can be either by adsorptive or by membrane technology. The process achieves high recoveries at reduced capital cost and at reduced product cost.

International Classification:

C03B 504

US Classification:

65 27

Abstract:

The present invention is an integrated process for the production of glass utilizing combustion heat to melt glassmaking materials in a glassmaking furnace. The fuel combusted to produce heat sufficient to melt the glassmaking materials is combusted with oxygen-enriched oxidant to reduce heat losses from the offgas of the glassmaking furnace. The process further reduces heat losses by quenching hot offgas from the glassmaking furnace with a process stream to retain the heat recovered from quench in the glassmaking process with subsequent additional heat recovery by heat exchange of the fuel to the glassmaking furnace, as well as the glassmaking materials, such as batch and cullet. The process includes recovery of a commercially pure carbon dioxide product by separatory means from the cooled, residual offgas from the glassmaking furnace.

International Classification:

C03B 5235

US Classification:

65 27

Abstract:

An integrated process for utilizing waste heat from a glass making furnace. The hot off-gas from the furnace is initially partially cooled, then fed to a reformer. In the reformer, the partially cooled off-gas is further cooled against a hydrocarbon which is thus reformed into a synthesis gas, which is then fed into the glass making furnace as a fuel. The further cooled off-gas is then recycled back to absorb the heat from the hot off-gas to perform the initial cooling.

International Classification:

C02F 1/20
B01D 19/00

US Classification:

203 2, 203 11

Abstract:

Method for removing dissolved gases from water to produce boiler feed water in a catalytic steam reforming process where boiler feed water is heated by indirect heat transfer with a reformate stream and/or a combustion product gas stream and the boiler feed water subsequently flash vaporized to form steam and residual liquid water, where the steam formed by flash vaporization strips the dissolved gases from the water.
