A reactor includes a shell and an insert in the shell. The insert includes an elongated center portion, a cross member extending outwardly from the center portion, and an outer portion extending laterally from a distal end of the cross member.

A catalyst arrangement disposed within a vertical reaction tube includes a structured catalyst within an upper part of the reaction tube, a particulate catalyst beneath the structured catalyst in a lower part of the reaction tube, and a catalyst support device located between the structured catalyst and the particulate catalyst, wherein the catalyst support device includes a cylindrical body having a first end adapted for connection to the structured catalyst, and a second end, and the cylindrical body has a diameter 70-90% of the internal diameter of the tube and a length/diameter in the range 0.5-2.5.

Method of loading a tubular reactor with a catalyst tube assembly, method of unloading a catalyst tube assembly from a tubular reactor, and catalyst tube assembly for a tubular reactor, such as a steam reformer, comprising an outer reactor tube having an inlet end and an outlet end opposite the inlet end, and including an inwardly protruding element; a centering assembly including an inner tube having an inlet end and an outlet end; a tubular boundary having a closed end and an open end.

A structured packing module for a gas phase reactor has a structured packing with a central axis extending along a longitudinal direction, and may further include an inner tube extending coaxially with the structured packing and along the longitudinal direction. The structured packing includes a plurality of corrugated sheets, each arranged circumferentially around the central axis and having a first end and a second end spaced apart from each other along the longitudinal direction. The corrugated sheets are arranged to radially overlap with each other such that corrugations of adjacently disposed corrugated sheets are arranged in a crisscross relationship. The structured packing module includes a gas flow path comprising at least one inter-sheet gas flow path defined between the adjacently disposed corrugated sheets.

The present invention relates to a packing structure made up of an ordered arrangement of bundles of tubes (1). For each tube bundle, tubes (1) are oriented in the four directions formed by the diagonals of a rectangular parallelepiped having one dimension larger than the others.

A rotor for rotating packed bed units (RPBs) is described. The rotor comprises a first plate and a second plate. The rotor further comprises a plurality of sets of rings concentrically interposed between the first plate and the second plate. Each set of rings comprises a plurality of rings are arranged cylindrically. Further, each ring comprises a plurality of packing elements. The rotor further comprises at least one metallic ring interposed between the plurality of sets of rings.

A casing having at least one tubular wall extending in a longitudinal direction (L) between two longitudinal ends, and an inner face that participates in delimiting a receptacle for a section of packing, the tubular wall participating in delimiting an input opening at one of its longitudinal ends The casing can also include a device configured to assist installation of a section of packing in the casing, which can include: a cradle which extends in an extension of at least part of the tubular wall from the input opening, in the longitudinal direction, opposite the base wall, the cradle being configured to position the section of packing facing the input opening; a removable cone which is configured to guide the section of packing by centring the section of packing on the input opening, wherein the longitudinal dimension of the cradle is larger than the longitudinal dimension of the removable cone.

A contactor media includes continuous surface segments, wherein a first continuous surface segment has at least 50% of its surface area follow at least one of: (a) a contour of a first zero-thickness surface having a Gaussian curvature (G.sub.c) of 400 mm.sup.2G.sub.c<0.01 mm.sup.2; and (b) a contour of a second zero-thickness surface having at least one principal curvature (k.sub.i) of 20 mm.sup.1k.sub.i<0.1 mm.sup.1; and wherein the first continuous surface segment provides at least: (a) a total liquid hold-up of between about 1 kg/m.sup.3 to about 800 kg/m.sup.3 or (b) a static liquid hold-up of about 0.1 kg/m.sup.3 to about 800 kg/m.sup.3.
