A support structure for a structured catalytic packing is disclosed. The support structure is in a fixed position relative to the reactor tube containing it. It supports catalyzed casings that are free to move relative to the support structure. The support structure and casings are inserted in the reactor tube such that the support structure is located proximate the longitudinal axis of the tube and the casings are located between the support structure and the reactor tube wall. The support structure comprises a central support tube or rod proximate to, and impervious or perforated discs perpendicular to, the longitudinal axis of the reactor tube, and may comprise spacers separating the discs.

Support structure for structured catalyst packings

High purity hydrogen is produced by a steam reforming hydrogen production unit with at least one of a bayonet reactor for reforming steam and a hydrocarbon, a recuperative burner, and a regenerative burner such that the steam reforming unit produces little or no steam in excess of the steam reforming process requirements. High purity hydrogen is separated from the syngas exiting the reformer via a pressure swing adsorption unit and combined with high purity nitrogen from an air separation unit as feedstock to a Haber process ammonia synthesis unit. Compressors for the ammonia synthesis unit are driven by higher efficiency drivers than are possible using the low temperature steam conventionally exported from a steam reforming unit. Compression power requirements are reduced.

Ammonia production method

A bayonet reactor including a catalytic reactor in the form of an annular structured packing is provided with increased surface area for the transfer of heat between annulus gas and return gas, an increased coefficient of heat transfer between the annulus and return gases, and a reduced overall pressure drop relative to conventional reactors. The reactors of the present technology can enable intensified catalytic processing.

Bayonet catalytic reactor

An apparatus includes an inlet, an outlet, and a sheet disposed proximate a heat transfer surface, wherein the sheet is oriented in a sheet plane that is displaced from a plane of the heat transfer surface by an angle of at least 10 degrees. The apparatus also includes a plurality of tabs attached to the sheet, the tabs lying in respective tab planes, wherein the tab planes and the sheet plane intersect forming respective intersections. The intersections of the tab planes and the sheet plane are substantially parallel. The intersections of the tab planes and the sheet plane are at an angle of less than 88&#xb0; to the heat transfer surface, and the plurality of tabs collectively form channels directing a fluid passing from the inlet to the outlet to impinge the heat transfer surface.

Engineered packing for heat exchange and systems and methods constructing the same

An apparatus includes a furnace having at least one bayonet reforming tube. The furnace is adapted to receive a gas including a hydrocarbon and at least one of steam and carbon dioxide via the bayonet reforming tube, heat and catalytically react the gas to form syngas at a first temperature, cool the syngas to a second temperature lower than the first temperature, and eject the syngas from the tube. The furnace has a first effluent stream including flue gas and a second effluent stream including syngas. The apparatus also includes a first heat recovery section adapted to transfer heat from the first effluent stream to a first heat load including one of air, water, and steam, and a second heat recovery section adapted to transfer heat from the second effluent stream to a second heat load.

A structured packing for insertion in a reactor having an inlet, an outlet, a wall and an axis. The packing comprises a first part, i.e., a reactor core and a second part, i.e., a reactor casing. The second part is free to move relative to the first part. The first part and the second part are inserted in the reactor such that the first part is located proximate the axis and the second part is located between the first part and the reactor wall. In general, the second part will be in contact with the reactor wall.

Reactor packing

An internal combustion engine in which the power output is controlled by modulating at least one of the compression ratio, expansion ratio, ratio of expansion rate to compression rate, air to fuel ratio, and steam to air ratio. Continuous isobaric catalytic combustion followed by isothermal expansion and the use of separate compressor and expander devices are used. Control dynamically maximizes fuel efficiency for the given power demand conditions. Power output is controlled by modulating flame temperature and/or pressure instead of by throttling. Lean combustion, high compression ratio, exhaust heat recuperation, and high power density and fuel economy are provided. External cooling is minimized or eliminated. Insulation of the engine effectively reduces energy losses to friction. Interchangeable use of gasoline, hydrogen and ammonia at high fuel efficiency is made possible for transitional periods of fuel availabilities. An injector suitable for isothermal expansion is provided.

Internal combustion engine

A catalytic reactor containing a core structure near the reactor axis and a casing structure near the reactor wall, the two structures differing from each other to promote catalysis and heat transfer, respectively. The casing contains a multiplicity of first devices for directing fluid centrifugally impinge a reactor wall and second devices for permitting fluid to flow away from a reactor wall as the fluid flows from the inlet to the outlet of the reactor.

Reactor with jet impingment heat transfer

A structured packing for a reactor is formed from a metal sheet to promote heat and mass transfer near the wall of the reactor. The structured packing causes lateral flow of fluids flowing through the packing such that jet impingement of at least one reactor wall is promoted. The packing may be used in a cylindrical, annular or plate-type reactor, e.g., a catalytic reactor, or a heat exchanger.

Reactor with primary and secondary channels

A method and an apparatus for controlling the operation of a digital processing system. In one example of a method of the invention, a first status indicator is received for a first software program which is executing on the digital processing system, and it is determined whether the first software program is in a first state. In response to determining that the first software program is not in the first state, then a first predetermined function is performed. In one embodiment, several additional status indicators may be received, one for each of several software programs which are executing on the system. For each additional status indicator, it is determined whether the corresponding software program is in the first state, and if it is not in the first state, then a corresponding, predetermined function is performed, such as (for example) relaunching the corresponding software. In one particular embodiment, the first status indicator, which indicates the first software program is not in a fault state, is provided by the first software program to another software program which is also executing on the system. In this particular embodiment, the first status indicator resets a counter which corresponds to the first software program and which is controlled by the another software program. The another software program determines the first software is in a fault state by examining a value of the counter.

A method of decarburizing molten metal in the refining of steel using neural networks with a first neural network trained to analyze data representative of many process periods of one or more decarburization operations for providing an oxygen count for a preselected gas ratio of oxygen to diluent gas to cause the temperature of the molten metal bath to be decarburized to rise to a specified aim temperature and with a second neural network trained to analyze data representative of many process periods of one or more decarburization operations for providing an output schedule of oxygen counts to be injected into the bath to reduce the carbon level to a predetermined aim level in one or more successive stages corresponding to a preselected schedule of ratios of oxygen to diluent gas.
