The invention relates to a lining (10) intended to be positioned inside a chamber (1) to promote contact between fluids circulating inside said chamber, said lining comprising a plurality of separate criss-crossing strips (12): —first strips (12.1i) parallel to a first direction (D1) and defining a plurality of first planes spaced apart from each other, —second strips (12.2i) parallel to a second direction (D2) forming an angle with the first direction (D1) and defining a plurality of second planes spaced apart from each other. In each first plane, a free space separates two first adjacent strips I a direction perpendicular to the first direction and receives a second strip, the first and second strips being secured together. Each separate strip of at least one stage is perforated (12) and selected from a strip made from a stamped metal sheet and a strip made from an expanded metal sheet.

A reactor for the synthesis of urea comprising a vertical shell and perforated baffles or trays (3) arranged to define compartments of the reactor, wherein each baffle comprises an array of individual perforated tiles (10) wherein each tile (101) comprises side walls (101A-101D) and a top face (101F), the side walls having first perforations for the liquid and said top face having second perforations for the gas, wherein said second perforations are smaller than said first perforations, and the tiles are distributed over the baffle with a two-dimensional pattern where adjacent tiles are separated by gaps (17).

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.

A structured packing module for crossflow applications is provided and includes a plurality of corrugated structured packing sheets positioned in an upright, parallel relationship to each other. The corrugations of adjacent structured packing sheets are in contact with each other and extend at a crossing angle. Apertures and raised ridges may be positioned on sidewalls of the corrugations. The structured packing module may be used in a crossflow contactor, such as in a process for removing carbon dioxide from air.

A packing device for mass and heat transfer with a subject fluid includes a housing having opposing ends, and subject fluid openings at each opposing end defining a subject fluid flow path for at least one subject fluid flowing through the packing device. A plurality of mass and heat transfer plates each include an interior heat exchange fluid channel disposed between interior heat transfer surfaces of the mass and heat transfer plates. A heat exchange fluid inlet and fluid outlet can supply and remove heat exchange fluid to the heat exchange fluid channels of the mass and heat transfer plates. The mass and heat transfer plates can be oriented to define there between fluid flow channels for the subject fluid. A method and system for mass and heat transfer with a subject fluid, and a method and system for the removal of CO.sub.2 from a gas stream are disclosed.
