  • Pack and column comprising one or more packs
  • the invention relates to a packing, in particular for use in columns for a material and optionally energy exchange, comprising a honeycomb body with first and second end faces arranged parallel to each other and a plurality of parallel to each other, extending from the first to the second end side flow channels for fluid media ,
  • the invention further relates to a column, in particular for use for the material and optionally energy exchange, comprising a housing having at least one inlet and at least one outlet and one or more packs arranged in a flow path of the housing extending from the inlet to the outlet are .
  • packing can be used in columns for the mass transfer and optionally energy exchange, in particular in industrial or rectification columns. Rectification columns are process plants for the separation of fluid mixtures.
  • packings can be used for the material and optionally energy exchange, for example in the exhaust air purification or gas scrubbing, wherein in gaseous media, such as exhaust air or gas to be washed, existing dirt particles pass into a washing liquid during mass transfer.
  • Fluid mixtures may contain, for example, liquid and / or gaseous components and, in addition, solid particles.
  • the packages When used in columns for the mass and optionally energy exchange, the packages must meet high requirements with regard to the flow behavior of the liquid and / or gaseous components, for example a flow deflection without major pressure losses on entry or exit into or out of a packing. It is also important that a homogeneous distribution of the fluid mixture prevails over the entire cross-section of the honeycomb body of the packing and, in particular, that no flow inhomogeneities are formed along a flow channel or along the surface of an end face.
  • the packs described therein comprise several superimposed packing layers.
  • the packing layers are made of preferably corrugated or folded metal sheets. A required there flow deflection between adjacent packing layers is supported by a so-called use between the packing layers.
  • the insert like the packing layers, has flow channels separated by channel walls.
  • the packages should have a low susceptibility to soiling, so that the packages do not have to undergo a complex cleaning procedure all too often.
  • the packs are typically used in columns for the mass and optionally energy exchange, which are operated continuously.
  • continuously operated columns for example a continuously operated rectification column
  • a start-up process may take several days after a standstill.
  • the packages in addition to the repair costs or new acquisition costs, there are also costs which are caused by the standstill and starting operation. For this reason, the packages should have the highest possible service life, so that repairs or replacement of components must be carried out only after the longest possible time intervals.
  • the object of the invention is to propose a package that take into account the above problems and are economical to produce.
  • the honeycomb body of a pack according to the invention is made from a first plastic material based on polytetrafluoroethylene (PTFE) polymer material, which has good temperature resistance and high resistance to chemicals, the pack according to the invention meets the high requirements with regard to temperature resistance and, secondly also given a high chemical resistance. Furthermore, no inserts within the packing have to be used for flow deflection in order to achieve optimized flow conditions, as is necessary in the prior art, for example in DE 197 06 544 A1. So only one type of component has to be used, which in turn reduces the number of different replacement parts that need to be ordered and stored.
  • PTFE polytetrafluoroethylene
  • honeycomb package of the present invention based on a PTFE polymer material-based first plastic material inherently has an antiadhesive surface, which makes it less susceptible to contamination than conventional metal packages.
  • the low levels of contamination, in particular solid deposits can be cleaned without residue, without the component having to be replaced by a new one.
  • packages according to the invention In contrast to packages made of metal, such as known from DE 197 06 544 AI, have packages according to the invention with honeycomb bodies of a PTFE based on polymer material first plastic material to a high corrosion resistance, which in combination with the general high chemical resistance to increased life of according to the invention leads packs.
  • honeycomb body of the packing according to the invention a honeycomb structure is formed with substantially parallel flow channels extending from the first to the second end of the honeycomb body and adjacent to each other via channel walls, an improved mixing can take place and the flow resistance can be kept small.
  • the honeycomb body preferably has flow channels with free cross-sectional areas, the sum of the free cross-sectional areas being approximately 70 to approximately 92%, in particular approximately 75 to approximately 85% of the area of an end face of the honeycomb body. This has the advantage that on the one hand the flow resistance is reduced and on the other hand an optimized mixing of the components can be made possible.
  • the honeycomb body of the package according to the invention in a cross section parallel to the first and second end faces is formed substantially circular.
  • This has the advantage that it results in a substantially round flow cross-section, which avoids inhomogeneities in the flow in corners in contrast to a square flow cross-section.
  • the honeycomb body is designed in several parts. In this preferred embodiment, it comprises two or more segments, which extend from the first to the second end side of the honeycomb body and have planar and optionally partially cylindrical sidewalls. Due to the formation of the honeycomb body in segments, a simplified handling can be realized parallel to the end faces even with a large cross sections of the honeycomb body.
  • planar side wall of a segment is not to be understood as a closed and smooth surface of the honeycomb body.
  • planar does not mean that the side wall can not comprise any projections and / or recesses.
  • Planar or partially cylindrical trained lateral Walls are in the context of the invention planar or cylindrical wall enveloping surfaces.
  • the individual flow channels of the honeycomb structure are polygonal, in particular rectangular, for example square, pentagonal or hexagonal, as seen in cross section parallel to the end faces of the honeycomb body.
  • a low flow resistance can be realized and on the other hand a sufficiently good mixing of the flowing media can be achieved.
  • the mixing of the components and the flow resistance in an optimized balance to each other.
  • the channel walls are formed in cross-section parallel to the end faces preferably with a height of about 5 to about 11 mm, in particular with a height of about 7 mm to about 10 mm.
  • the channel walls of the flow channels of the honeycomb structure have a thickness of about 0.8 mm to about 2.1 mm.
  • the first plastic material is preferably processable by a pressing / sintering technique. Subsequent machining may allow customization of the honeycomb body.
  • the first plastic material of the honeycomb body is thermoplastically processable, which is advantageous in the production of the honeycomb body.
  • the first plastic material of the honeycomb body has a thermal conductivity of about 0.3 W / (m-K) or more, and / or the first plastic material of the honeycomb body has a specific heat capacity of about 0.9 J / (g-K). or more.
  • This has the advantage that, for example, heat of reaction or process heat, which arises during the mass transfer, can be dissipated via the heat-conductive channel walls of the honeycomb structure.
  • areas in which a higher temperature prevails, so-called hot spots, can be avoided and a sufficiently uniform temperature distribution over the entire package can be realized.
  • Particularly preferred first plastic materials have fillers-optimized thermal conductivities, for example about 0.43 W / (m-K) at a specific heat capacity of 1.24 J / (g-K) measured on a material sample with a filler content of 3 wt. % of a graphite-based filler C-THERM TM 002, particle size D 50 about 38 pm (available from TimCal Graphite & Carbon).
  • These fillers, via which the thermal conductivity of the first plastic material can be optimized, are also referred to below as heat-conducting pigments.
  • the PTFE polymer material to a density of about 2.0 to about 2.2 g / cm 3.
  • the first plastic material has a temperature resistance of about 200 ° C or more, in particular about 250 ° C or more.
  • the packings according to the invention can thus also be used in separation processes with special requirements in which such high temperatures prevail or arise.
  • the material properties of the first plastic material of the honeycomb body are decisive for the properties of the pack according to the invention.
  • the first plastic material of the honeycomb body preferably has a tensile strength of about 10 to about 30 N / mm 2 measured according to EN ISO 12086-2. This has the advantage that packages can withstand mechanical stresses without tearing. Thus, improved handleability during installation and replacement of packages according to the invention in columns can be made possible. In addition, damage in transit can be reduced.
  • the first plastic material of the honeycomb body according to test standard EN ISO 12086-2 has an elongation at break of about 220 to about 350%. This, like the improved tear resistance, is advantageous for handling during installation, replacement and transport of the packings according to the invention.
