Gas-liquid contact apparatus comprising a packed bed formed of at least two superimposed layers of fabricated packings including an upper layer of randomly dumped members comprising ribbed tubular elements and a lower layer of stacked packing elements.
An apparatus for the anaerobic filtration of waste water includes a filter of filling material through which the waste water to be treated is passed from the bottom to the top. The filter includes upper and lower superposed layers of filling material separated by an intermediate layer of material. The lower layer is in the form of an ordered arrangement of the material thereof. The upper and intermediate layers each include a loosely packed arrangement of the material thereof.
A mass-transfer column consisting of one or more contact zones. The contact zones are exclusively provided with packings placed in prearranged locations. In the contact zones, optimal operating conditions for the packings are created over the entire height of the contact zones in order to achieve a minimal pressure loss at a concomitant high separating efficiency. This is done by implementing a suitable gradated adaptability of the packing to the vapor and liquid loads varying over the height of the contact zones.
A cryogenic air separation system using a random packing section below a section of structured packing and redistributing liquid between sets of random and structured Packing sections.
A carburetor for an internal combustion engine comprises a housing, porous matter contained in the housing, means for injecting fuel into the housing and onto the porous matter to effect completion of vaporization of the fuel, means for admitting air into the housing to form a mixture with the vaporized fuel and means for conducting the mixture out of the housing for combustion in the engine.
A cryogenic distillation system employing a multisection column wherein structure packing of different packing density is employed in at least two sections of the column.
