Appl. No.:

10/800227

Carl Udovich - Joliet IL, US

International Classification:

F16L047/00

US Classification:

285290100

Abstract:

Composite joints for gas-tight members that exhibit different coefficients of thermal expansion are disclosed. Broadly, apparatus of the invention provides composite joints which include a girdle of a resilient material disposed between mating surfaces of a high strength metallic member and a nonmetallic member in an arrangement wherein a difference in fluid pressures across the joint provides compressive force upon the girdle through tapered mating surfaces thereby improving resistance to fluid leakage. Composite joints of the invention are particularly useful for joining a high strength weldable metallic conduit and a gas-tight ceramic member having a tubular structure, closed at one end, with a tapered mating surface at a distal end thereof contiguous with a portion of the girdle. Processes beneficially using joints in accordance with the invention include converting methane gas into value-added-products, for example, production of synthesis gas comprising carbon monoxide and molecular hydrogen. Advantageously, the synthesis gas is free of deleterious and/or inert gaseous diluents such as nitrogen.

International Classification:

C07C 5/327
C07C 5/373

US Classification:

585654000, 585658000

Abstract:

Processes for chemical conversion of volatile organic compounds to value added products using multiphasic membrane reactors are described. More particularly the multiphasic materials comprising two or more phases bound to one another which in the form of a solid state membrane demonstrate an ability to selectively convey electrons, hydrogen and oxygen between different gaseous mixtures. Characteristics of such multiphasic materials provide independent, controllable, counter-current transport of hydrogen, electrons and oxygen.

International Classification:

G02B 27/00
E21B 7/15

US Classification:

359896, 175 16

Abstract:

A method and apparatus for transmitting light through a light absorbing medium in which a light transmissive fluid column or channel contiguous with the light absorbing medium is formed in the light absorbing medium. The light is introduced into a light inlet end of the column of light transmissive fluid, whereby the light is transmitted in the column of light transmissive fluid through the light absorbing medium until exiting a light outlet end of the column. The invention has applicability to the field of fiber optics and downhole applications of lasers, such as for wellbore drilling and completion activities.

International Classification:

E21B 43/11

US Classification:

166297

Abstract:

A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.

International Classification:

E21B 43/11

US Classification:

166297, 166 551

Abstract:

A method and apparatus for wellbore perforation in which a laser beam at a downhole location of a wellbore is directed to a target area of a wellbore wall to be perforated. The laser beam is guided through a longitudinally extensible nozzle onto the target area and a purge fluid is introduced into the longitudinally extensible nozzle, thereby longitudinally extending the nozzle toward the target area. The purge fluid in the longitudinally extensible nozzle is passed through a purge fluid outlet of the nozzle onto the target area, thereby removing debris from the target area generated by the laser beam.

US Classification:

429 8

Abstract:

This invention discloses cross-flow electrochemical reactor cells containing oxygen permeable materials which have both electron conductivity and oxygen ion conductivity, cross-flow reactors, and electrochemical processes using cross-flow reactor cells having oxygen permeable monolithic cores to control and facilitate transport of oxygen from an oxygen-containing gas stream to oxidation reactions of organic compounds in another gas stream. These cross-flow electrochemical reactors comprise a hollow ceramic blade positioned across a gas stream flow or a stack of crossed hollow ceramic blades containing a channel or channels for flow of gas streams. Each channel has at least one channel wall disposed between a channel and a portion of an outer surface of the ceramic blade, or a common wall with adjacent blades in a stack comprising a gas-impervious mixed metal oxide material of a perovskite structure having electron conductivity and oxygen ion conductivity. The invention includes reactors comprising first and second zones seprated by gas-impervious mixed metal oxide material material having electron conductivity and oxygen ion conductivity. Prefered gas-impervious materials comprise at least one mixed metal oxide having a perovskite structure or perovskite-like structure.

Abstract:

The present invention relates to composite materials for membrane reactors which include a gas-tight ceramic, a porous support, and an interfacial zone therebetween. More particularly, this invention relates to composite materials using oxygen ion-conducting dense ceramic membranes formed on a porous support comprising a metallic alloy to provide an interfacial zone identifiable by a gradient of composition in at least one metallic element across the interfacial zone between the dense ceramic membrane and the porous support. Processes using composite materials in accordance with the invention are, for example, used for production of synthesis gas comprising carbon monoxide and molecular hydrogen which synthesis gas is, advantageously, free of deleterious and/or inert gaseous diluents such as nitrogen.
