Abstract:

A system for coating a surface comprising providing a source of iron-based amorphous metal, the iron-based amorphous metal including devitrified ferrite; directing the iron-based amorphous metal toward the surface by a spray for coating the surface; and separating at least a portion of the devitrified ferrite from the spray before the spray reaches the surface. Also an apparatus for coating a surface comprising a source of iron-based amorphous metal, the iron-based amorphous metal including devitrified ferrite; an application system for directing the iron-based amorphous metal toward the surface by a spray for coating the surface, and a system for separating at least a portion of the devitrified ferrite from the spray before the spray reaches the surface.

International Classification:

G01N 27/26
G06F 19/00

US Classification:

205775, 702 30

Abstract:

A method for characterizing refinery feedstocks according to their corrosivity is provided. The characterization is based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, and/or dissociation of sulfur compounds in the feedstocks. In one embodiment, the characterization is done via vibrational spectroscopic measurements over a range of temperature, e.g., from ambient to 700 F. The method can be practiced in any of refinery, terminal, and laboratories. It can be used in conjunction with models and hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks.

US Classification:

205782, 205775, 2057865, 324700

Abstract:

Refinery feedstocks can be characterized based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, and/or dissociation of sulfur compounds in the feedstocks. The characterization is performed as a function of temperature via any of electrical resistivity measurement, vibrational spectroscopic analysis, voltammetry, electrochemical impedance spectroscopy (EIS) and combinations thereof The method can be practiced in any of refinery, terminal, and laboratories. It can be used in conjunction with models and hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks. In one embodiment, the characterization of refinery feedstocks is via the use of EIS.

International Classification:

C10L 1/04

US Classification:

208 14

Abstract:

A method for characterizing and optimizing refinery feedstock blends according to their corrosivity is provided. Refinery feedstocks can be characterized based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, mass changes of carbon steel samples, and/or dissociation of sulfur compounds in the feedstocks. The characterization is performed as a function of temperature via any of electrical resistivity measurement, vibrational spectroscopic analysis, voltammetry, electrochemical impedance spectroscopy, crystal microbalance measurements of weight changes, and combinations thereof. The method employs models and/or hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks.

International Classification:

G06F 19/00

US Classification:

702 25

Abstract:

A system for characterizing and optimizing refinery feedstock blends according to their corrosivity is provided. Refinery feedstocks can be characterized based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, mass changes of carbon steel samples, and/or dissociation of sulfur compounds in the feedstocks. The characterization can be carried out via any of impedance, spectroscopic measurements, and continuous measurements of mass changes of carbon steel samples with a crystal microbalance over a range of temperature, e.g., from ambient to 750 F. The system can be employed in any of refinery, terminal, and laboratories, using models and/or hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks.

6/702165

Inventors:

Thomas M. Devine - Moraga CA

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23K 2016

US Classification:

228194

Abstract:

A method for the diffusion bonding of a graphite member to a metallic surface of molybdenum, molybdenum alloy, tungsten or tungsten alloy as part of a composite rotary anode for an X-ray tube is set forth. In the completed structure a crack-free compound laminate separating and joining the graphite member and the metallic surface comprises a layer of carbide of metal of the metallic surface bonded to a layer of platinum or platinum alloy.
