US Patent:

50080857, Apr 16, 1991

Filed:

Mar 31, 1989

Appl. No.:

7/332508

Inventors:

Richard L. Bain - Golden CO
John R. Larson - Boulder CO

Assignee:

Resource Technology Associates - Tulsa OK

International Classification:

G05D 700

US Classification:

422109

Abstract:

An apparatus is disclosed for improving the transportability of a hydrocarbon stream by reducing its viscosity. The apparatus comprises a reactor vessel useful for providing an incremental amount of heat to a hydrocarbon stream by the introduction of an oxidizing agent into the core portion of the stream. The reactor comprises an influent conduit and an effluent conduit in heat exchange relation with each other, at least one oxidant injection nozzle located in either or both the influent and/or effluent conduits, a conduit to transport oxidant to the nozzles and a valve in the oxidant conduit to control oxidant flow to the nozzles. The reactor can also contain temperature monitors in the influent and/or effluent conduits and an oxidant flow controller device responsive to output from the temperature monitors and adapted to adjust oxidant flow to maintain temperatures in the reactor reaction zone within a preselected range.

International Classification:

C10G 914
C10G 900

US Classification:

208132

Abstract:

A method is disclosed for improving the transportability of a hydrocarbon composition by passing an influent feed stream of composition into a downcomer to provide a hydrostatic column of fluid. The influent stream is heated by heat exchange with an effluent product stream wherein at least one of the streams is in turbulent flow. The feed stream is pressurized by the hydrostatic pressure head to a reaction pressure of at least about 1000 psi. The heated and pressurized feed stream is contacted with an active heat source in a reaction zone to increase the temperature of the feed stream to a reaction temperature of between about 300. degree. C. and the coking temperature of the hydrocarbon composition. The temperature differential between the active heat source and the feed stream in the reaction zone is maintained at less than about 30. degree. C. to provide a treated effluent stream which is brought into heat exchange contact with the influent stream.

Appl. No.:

8/584057

Inventors:

John G. Larson - Alpharetta GA
David Brugger - Bossier City LA

Assignee:

GNB Technologies, Inc. - Mendota Heights MN

International Classification:

H01M 474

US Classification:

429242

Abstract:

A method of continuously making plates for a lead-acid battery, and the resulting battery, comprise providing an electrically conductive strip of a lead or lead alloy which is fed into a grid expander which converts the strip into a continuous mesh having a top and bottom bar, feeding the continuous grid mesh into a tab blanker to form the lug for each plate in the top bar and notching the top and bottom bars at spaced locations so that what becomes the corners of the top and bottom frame bars are notched, thereafter pasting the continuous grid mesh with active material paste and then dividing the continuous grid mesh into individual plates, the method disclosed providing a process capable of being reliably run at commercial rates of speed with minimal scrap rates due to separator punctures and the like, the process thus providing sufficiently wide processing latitude which, in the preferred embodiment, can even significantly minimize out-of-specification grids that would otherwise would have to be scrapped.

International Classification:

C10G 900
C07C 3700

US Classification:

208106

Abstract:

A method is disclosed for reducing the viscosity of a hydrocarbon feed. The feed is heated from an initial temperature to a second temperature and an oxidizing agent is introduced to oxidize components in the feed and provide heat to increase the temperature of the feed to a reaction temperature. The reaction temperature is maintained to produce a reaction product having a lower viscosity than the feed.
