Abstract: A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

Abstract: The invention relates to a solid shaped body (1) having a cylindrical form with a first base area (3), a second base area (5) and a lateral area (7), wherein the solid shaped body (1) comprises a first number of flutes (9) in the lateral area (7), each extending from the first base area (3) to the second base area (5), and a second number of openings (11), each extending from the first base area (3) to the second base area (5), and wherein the second number of openings (11) is in a range from 2 to 8, the second number of openings (11) is larger than the first number of flutes (9) and wherein a ratio between a first radius (13) of at least one flute (9) and a second radius (15) of at least one opening (11) is at least 1.15. The invention further relates to a use of the solid shaped body (1).

Abstract: A method for controlling temperature of a chemical reaction without measuring a temperature of the chemical reaction. Changes in mass of a chemical reaction are monitored and are used to calculate the temperature of the system. The reaction can be maintained at a desired temperature (T) without measuring the temperature. The disclosed method is useful for reactions that occur at non-equilibrium conditions where any measured temperature would presume steady-state conditions.

Abstract: The present disclosure relates to an absorber column apparatus for removing a selected component of a gas. The apparatus may have a first zone, a second zone and a third zone, wherein the first and third zones form a first domain through which a first fluid laden with a select gaseous component to be removed therefrom flows along concurrently with a second fluid. The second fluid at least substantially removes the select gaseous component from the first fluid to create a third fluid. The first fluid leaves the absorber column as a fourth fluid with the select gaseous component at least substantially removed therefrom. The second zone forms an active packing zone including a structure which forms an independent second domain in thermal communication with the first domain. The second receives a quantity of the third fluid and channels it through the second zone to help cool at least one of the first and second fluids.

Abstract: Assemblies, apparatuses, systems, and method to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly to enhance conveyance the material from the source of the material. The vacuum generation and sound attenuation assembly may include a vacuum source including a plurality of vacuum generators. Each of the plurality of vacuum generators may be positioned to cause a vacuum flow between the source of the material and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber connected to the vacuum source. The sound attenuation chamber may include an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source.

Abstract: 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.
