The present technique presents a structured packing module 100 for a gas phase reactor 2, the structured packing module 100 comprising a structured packing 1 having a central axis 5x extending along a longitudinal direction, and may further comprise an inner tube 5 extending coaxially with the structured packing and along the longitudinal direction. The structured packing 1 includes a plurality of corrugated sheets 10, 20, 30, each arranged circumferentially around the central axis 5x and having a first end 101 and a second end 102 spaced apart from each other along the longitudinal direction. Each corrugated sheet 10, 20, 30 includes corrugations 9 extending between the first end 101 and the second end 102 and disposed at an acute angle A greater than or equal to 5 degree and less than or equal to 30 degree with respect to a line 5y parallel to the central axis 5x. The corrugated sheets 10, 20, 30 are arranged to radially overlap with each other such that the corrugations 9 of adjacently disposed corrugated sheets 10, 20, 30 are arranged in a crisscross relationship. The structured packing module 100 includes a gas flow path 40 comprising at least one inter-sheet gas flow path 42 defined between the adjacently disposed corrugated sheets 10, 20, 30.

A reactor system and a process for carrying out steam cracking of a feed gas comprising hydrocarbons is provided, i where the heat for the reaction is provided by resistance heating by means of electrical power, so that a product stream comprising at least one olefin compound is obtained.

The main subject of the present invention is a process for installing a section of packing in a casing by means of a device to assist installation of a section of packing, the casing comprising at least one tubular wall extending in a longitudinal direction (L) between two longitudinal ends, and an inner face of which participates in delimiting a receptacle for the section of packing, the tubular wall participating in delimiting an input opening at one of its longitudinal ends, the casing comprising a base wall positioned at the longitudinal end opposite the input opening, the casing being positioned horizontally during the process for installing the section of packing, the process comprising a step of fitting of the device to assist installation on the casing, during which the device to assist installation is secured in the vicinity of the input opening of the casing, a step of positioning of the section of packing relative to the device to assist installation and to the input opening, and at least one step of pushing during which the section of packing is pushed into the receptacle of the casing.

A contactor includes a random packing arrangement in several compartments. The compartments can be delimited by perforated plates or by structured packing walls. A heat and/or material exchange column is equipped with such a contactor. A floating structure includes such a column. A column equipped with such a contactor can be used for a gas treatment, CO.sub.2 capture, distillation or air conversion process.

A method for enabling gas exchange and chemical reactions with one or more liquid streams contained in a reactive process vessel are provided. One or more exchange layers within the process vessel can be composed of both collector media and releaser media. The exchange layers allow elements to facilitate increased performance of vessel operations by promoting gas component mixing and diffusion. Improved rates of gas component exchange mean less coking and more gas components available for reaction.

The present invention describes a packing with a three-dimensional structure which is particularly suited to creating homogenous and anisotropic mixing between the gas phase and a dispersed solid phase moving in counter-current flow. Application of this packing to the stripper of fluidized catalytic cracking units.

Process vessels can contain one or more entry zones containing stability-improving materials. The entry zones address bed movement and filtration problems. The stability-improving material can be positioned above a treating zone or above a processing bed within the vessel. Entry Zones are intended to improve the stability of downstream operations.
