The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

A distillation column including a plurality of alternating plates and spacers stacked in a z-direction is provided. The plates include a respective liquid channeling network on a top surface thereof, a respective vapor opening, and a respective descending ramp. The respective descending ramps abut a respective liquid feed location of the plate immediately below to form a continuous liquid channeling network. The respective vapor openings of adjacent plates are located on opposite sides of the distillation column and form a continuous S-shaped vapor channel defined by the plurality of alternating plates and spacers, and the respective vapor openings. Systems including such distillation columns and processes of distilling a fluid mixture are also provided.

The invention relates to packed contact devices used in heat/mass exchange column apparatuses in which the processes of rectification, distillation, absorption, and extraction are run, and can be applied in the oil refining, petrochemical, chemical, gas-processing, and food-manufacturing industries. A contact device for carrying out heat/mass exchange and separation of phases in sectional cross-flow packed columns in gas/liquid and liquid/liquid systems comprises a plurality of identical contact elements assembled one upon another in one or more rows in blocks held together by spokes and vertical posts, with formation of walls in the column body that are restricted on horizontal end faces by horizontal segmental baffles conjugated in an arc with the column body; thereat, arranged between the walls are liquid distributors having a perforated part, an additional baffle, deflector plates, and vertical support plates. The space between the lower and upper walls is sealed by means of battens.

A fill pack includes a first fill sheet defining an air intake edge, an air exit edge and an airflow axis extending between the air intake edge and the air exit edge. The first fill sheet defines a first flute section having a first inlet end, a first outlet end and a first peak extending between the first inlet end and the first outlet end. A second fill sheet defines a second flute section having a second inlet end, a second outlet end and a second peak extending between the second inlet end and the second outlet end. The first peak extends relative to the second peak such that a first flute portion defined by the first and second flute sections has a cross-sectional shape that changes between the first and second inlet ends and the first and second outlet ends.

A packing for gas-liquid contact has at least one packing element of a thin layer shape, placed in a standing position. The packing element has a main body portion having a planar liquid film-forming surface extending along a liquid flow direction, and at least one wall portion provided to stand relative to the liquid film-forming surface and extending along the liquid flow direction. The wall portion has a side surface inclined at a predetermined angle to the liquid film-forming surface in a surface position of a liquid film to be formed by a liquid on the liquid film-forming surface.

A catalytic reactor includes: a reaction-side flow channel in which a reaction fluid flows; structured catalysts accommodated in the reaction-side flow channel. Each structured catalyst includes inclined surfaces in at least part of each of two surfaces facing other structured catalysts. The inclined surfaces are inclined in the same direction with respect to an arrangement direction of the structured catalysts.

A corrugated structured packing sheet has surface texturing that may be in the form of a grid of indented and raised structures. Each indented structure is separated from some or all of adjacent ones of the indented structures by the raised structures. The raised structures form rows of peaks and interconnecting saddles. Microchannels extend along adjacent ones of the indented structures and the interconnecting saddles and intersect the corrugation valleys at an angle in the range of 20 to 75 degrees. The surface texturing may be or include wavy parallel grooves in an upper edge region adjacent the upper edge and a lower edge region adjacent the lower edge and may be or include parallel groove segments in the bulk region that are oriented obliquely to upper and lower edges of the structured packing sheet.
