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 contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

The present invention relates to a saturator. The present invention further relates to a method for reusing a waste water stream from a Fischer-Tropsch reactor. The invention further relates to system for recycling waste water from a Fischer-Tropsch reactor preferably within a gas-to-liquids (GTL) plant.

A device is provided having a structure for conducting a first fluid, the structure having in addition an interface for conducting a second fluid. The first fluid can be brought into contact with the second fluid at the interface of the structure. A flow interrupter (120.0) for interrupting a flow of the second fluid is situated at the interface of the structure.

A mechanical assembly for securing a first sheet to a second sheet includes a first projection having a first sidewall and a first top wall. The first sidewall extends from the first top wall at a first acute angle. The first sidewall includes a first top end and a first bottom end. A first discontinuity is defined in the first sidewall between the first top end and the first bottom end. A first base wall extends from the first bottom end. The first base wall extends generally parallel to the first top wall.

A high capacity and high efficiency vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by a half module comprising a downcomer against a shell of a vessel for transporting liquid to a subjacent stage which utilizes a demister to effect vapor-liquid separation at the downcomer outlet.
