  • Patent number: 9988330
    Abstract: In a process for the production of higher alcohols, i.e. C4+ alcohols, from syngas, the syngas is first reacted in a heterogeneous alcohol pre-converter (A) using an alcohol synthesis catalyst, whereby methanol as the main product in a concentration corresponding to or close to the equilibrium concentration is produced. Then the effluent from the pre-converter is mixed with unconverted wet recycle gas and reacted in a heterogeneous reactor for higher alcohols synthesis (B) containing a higher alcohols synthesis catalyst, and finally the effluent from the reactor for higher alcohols synthesis is separated into (i) unconverted syngas, which is recycled to the higher alcohols synthesis reactor, (ii) methanol and light alcohols, which are recycled to the higher alcohols synthesis reactor, and (iii) the final product consisting of higher alcohols.

  • Patent number: 8602397
    Abstract: A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.

    Abstract: A collector-distributor combination in a column, which is filled with a random packed bed or with a structured packing, is disclosed. The liquid phase is guided over a collector with inclined planes to a central opening, which is connected to an ascending pipe, from which the liquid phase is distributed to the plane underneath via the distributor pipes. By guaranteeing a constant filling level of the liquid phase in the ascending pipe, the distributor functions as a pressure distributor. The liquid phase is distributed independent of the inclination of the column over the entire length of the distributor pipes. The gaseous phase passes through the collector via the chimney.

  • Patent number: 8096533
    Abstract: A stacked packing column for heat and/or mass transfer has individual horizontal layers including a lower layer that has a greater density that initiates an accumulation, in particular flooding, and that is 1.5 to 10, preferably 2 to 3 times, greater than the density of an overlying upper layer. The upper layer forms oblique flow channels having lower sections that are more vertically aligned than respective upper sections. The lower sections of the flow channels have a larger cross section than the upper sections, and the sections of larger cross section open into the lower layer.

  • Patent number: 7997562
    Abstract: A tower/frame structure of interconnected columns and beams (which may be used in a cooling tower) and novel columns, beams, connection mechanisms and other components are provided. In one embodiment, a column and a beam are constructed of pultruded composite fiber-reinforced plastic (FRP) materials. The beam includes two sidewall extensions or flanges (each having one or more attachment apertures) at one end and which are integral with the beam for connection to the column (having one or more corresponding attachment apertures). The dimension/spacing between the inner walls of the two flanges substantially equals or is slightly larger than the outer dimension of the column. The attachment holes are aligned and a fastener is inserted through the extensions and column for attaching the column and beam. The C-shaped end of the beam substantially conforms to the cross-sectional shape and dimensions of the column.

  • Patent number: 7862011
    Abstract: An evaporative cooler, including one or more media, distributes water from a source of water to each media through a constant flow valve. A distribution unit at each media includes a pair of spray bars for spraying water through two rows of uniformly spaced apertures disposed in each spray bar. A spray bar channel associated with each spray bar distributes the streams of water impinging thereupon from one row of apertures to the underlying media in specific locations. A distribution cap associated with each spray bar distributes streams of water impinging thereupon to the front and back edges of the underlying media. The water dripping from the media is drained. A fan or other air moving device draws air through the media to obtain cooled air resulting from evaporation of water flowing downwardly along the media.

  • Patent number: 7815700
    Abstract: A device, system and method of mixing two fluids are described herein. A gaseous first fluid is distributed through a distribution zone to a mixing zone by a bundle of pipes parallel to an axis inside which the first fluid is uniformly distributed. A second fluid is uniformly distributed outside the pipes in the distribution zone. The mixing zone is separated from the distribution zone by a pipe-plate supporting the pipes. The pipe-plate has slits or openings to uniformly discharge the second fluid in an axial flow direction into the mixing zone. The pipes extend beyond the pipe-plate into the mixing zone to partialize an outlet flow of the first fluid. In one aspect, the pipes have different lengths to partialize the outlet flow. In another aspect, a terminal portion of the pipes partializes the outlet flow axially, radially, transversally or a combination thereof in the mixing zone.
