The present invention relates to a device for inserting at least one packing section into a cylindrical shell, comprising a base provided with gripping means configured to grip hold of a packing section and arranged at regular intervals around a main axis, wherein the insertion device comprises at least two telescopic devices secured to the base and at least one pushing means secured to one end of each of the two telescopic devices, the telescopic devices being configured to extend and cause the pushing means to move.

The disclosure provides a structure that is used in the treatment of a fluid. The packing structure comprises a body having an axis. The packing structure also has at least one curved flow path that rotates around, and extends along at least a portion of, the axis of the body.

A casing intended to be equipped with at least one section of packing for a gas/liquid separation column comprises at least a tubular wall extending along a longitudinal direction between two longitudinal ends and an internal face of which contributes to delimiting a housing for the section of packing, the tubular wall contributing to delimiting, at one of its longitudinal ends, an entry opening, the casing comprising an end wall located at the opposite longitudinal end to the entry opening, the casing comprising at least a first hooping device and at least a second hooping device which are positioned around the tubular wall of the casing in contact with an external face of the tubular wall, the first hooping device comprising at least one zone of connection with a movement system for the moving of the casing, the second hooping device having a longitudinal dimension shorter than a longitudinal dimension of the first hooping device.

A packing section intended to be installed in a casing so as to form a gas/liquid separation column comprises a block for treating a fluid that has a generally cylindrical shape extending along a longitudinal direction, the treatment block being formed by a stack of plates for treating the fluid along the longitudinal direction, the treatment block having a first disc-shaped face and a second disc-shaped face that each extend in planes parallel to one another, the treatment block having an external face extending over the perimeter of said treatment block between the first disc-shaped face and the second disc-shaped face, the packing section having at least one element for holding the treatment block that extends at least partially around the external face of the treatment block, the holding element having a portion for holding the treatment plates of the treatment block in position.

A catalytic reactor according to an embodiment includes a catalytic unit including at least one catalyst having a honeycomb structure in which a plurality of passages extending in an axial direction are formed, a reactor housing accommodating the catalytic unit, and a seal plate sealing between an outer periphery of the catalytic unit and an inner periphery of the reactor housing. The seal plate seals between the outer periphery of the catalytic unit and the inner periphery of the reactor housing at an upstream end portion of the catalytic unit with respect to a flow of a fluid flowing in the reactor housing.

The invention includes a reactor installation device comprising a flexible band, a first tab, a second tab, and a mechanical stop. The flexible band has a first end, a second end, a top edge and a bottom edge. The first tab is attached at or near the first end, the second tab is attached at or near the second end, and the both tabs are attached at or near the top edge of the flexible band. The mechanical stop is attached to the flexible band, the first tab, and/or the second tab, between the top edge and the bottom edge of the flexible band. The flexible band is capable of being bent into the shape of a circle by bringing the first and second tabs into contact. The invention also includes a method of inserting a skirt seal into a stackable structural reactor using the reactor installation device.

The invention relates to a fluid collection device (8), in particular a support collector unit, for collecting fluid flowing through a packing (4) of a material exchange column (1). The fluid collection device (8) includes a support ring (11), a plurality of support profiles (12-16) secured to the support ring (11) for supporting the at least one packing (4), and a plurality of collection channels (19-21) secured to the support ring (11) for collecting the fluid. The collection channels (19-21) are positioned in parallel to the support profiles (12-16) and the support profiles (12-16) are arranged in such a way that they are each arranged in a no-flow area (40, 41) of one of the collection channels (19-21).

The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

A catalytic distillation structure that may include a rigid framework having at least two grids with a plurality of horizontal fluid permeable tubes mounted to said grids to form a plurality of fluid pathways among the plurality of horizontal fluid permeable tubes. Additionally, each horizontal fluid permeable tubes may have a profile of a six-sided polygon. Further, the catalytic distillation structure may include a plurality of vertically plates or wires connecting vertically aligned tubes of the plurality of horizontal fluid permeable tubes. Furthermore, the plurality of vertically plates or wires connects from a corner of one vertically aligned tubes to a corner of an adjacent vertically aligned tube.
