Definitions

  • the invention is based on a bottom for a mass transfer column having openings, wherein a deflecting element is positioned above each opening, so that each opening has an entry surface on the underside of the bottom and at least two exit surfaces between the surface of the bottom and the deflecting element.
  • the invention further relates to a mass transfer column and a use of the soil.
  • Mass transfer columns can be used in all processes in which a gas phase and a liquid phase are to be brought into contact with each other. Corresponding processes are, for example, distillation processes, rectification processes, condensation processes or absorption processes.
  • the mass transfer columns used usually contain internals. Such internals are, for example, trays, structured packings or random packings. If trays are used as internals, the shape and shape of the trays depends on the process carried out. In the case of the floors used, a distinction is made between those with forced guidance of the liquid and those without positive guidance.
  • Floors with a positive guide have at least one drainage channel for liquid through which the liquid drains to the soil below.
  • the downcomer acts as a feed to the soil, which is positioned below the downcomer.
  • the drainage shafts of superimposed trays are usually arranged at opposite positions.
  • soils without forced guidance of the liquid do not have separate drainage shafts. Rather, the liquid drains through openings in the soil to the underlying soil.
  • Such trays without positive guidance of the liquid are also referred to as dual-flow trays. These soils are used in particular in processes which have a high tendency to soiling.
  • Mass transfer columns with dual-flow trays are described, for example, in WO-A 03/043712 or in WO-A 2004/063138.
  • sieve trays are preferably used as dual-flow trays.
  • the object of the present invention was to provide a bottom for a mass transfer column, with which compared with the known soils a longer contact time and thus a better soil efficiency while maintaining the properties with respect to contamination, can be achieved.
  • each opening a deflecting element is positioned so that each opening has a first free cross-sectional area at the bottom of the bottom and a second free cross-sectional area between the surface of the bottom and the deflecting element, characterized in that the bottom further comprises openings without deflecting element.
  • the soil may be a soil with forced guidance of the liquid or a soil without forced guidance of the liquid, that is a so-called dual-flow soil.
  • the floor according to the invention is a dual-flow floor, so that the floor has no downcomer.
  • the openings without deflecting evenly distributed on the floor are arranged. Due to the uniform arrangement of the openings without deflecting a uniform contact of gas and liquid is achieved especially in soils without forced guidance of the liquid. Such uniform contact ensures, for example, that no local differences in the properties of the liquid, for example the concentration of the individual components in the liquid or the temperature, are established on the soil. Furthermore, it has been found that a higher liquid layer is formed over the openings without deflecting element than over the openings with deflecting element. As a result, the liquid preferably flows through the openings without deflecting element and the gas preferably flows through the openings with deflecting element due to the lower counter-pressure.
  • Uniform arrangement means that the openings without the deflection element are the same area and the same area openings are arranged distributed without deflecting over the entire ground and the surface portions per opening without deflecting differ by not more than 20% from each other.
  • the area fraction per opening without deflection element is understood to be the area of the floor which is enclosed by the connecting lines of the axes of the openings adjacent to the opening without deflecting element without deflecting element.
  • a flow can be generated by a non-uniform arrangement of the openings without deflecting element on a dual-flow tray, as can be set by different amounts of liquid flowing and rising gas through the liquid different amounts of liquid on the ground. Since a higher amount of liquid at one point leads to a wave crest on a ground and this runs off in the direction of a point with a lower amount of liquid, a flow sets in on the ground.
  • the proportion of the free cross-sectional area of the openings without deflection element is preferably 1 to 30% of the smallest free cross-sectional area of all openings of a floor. In a particularly preferred embodiment, the proportion of the free cross-sectional area of Openings without deflecting 5 to 15% of the smallest free cross-sectional area of all openings of a floor.
  • the free cross-sectional area of the openings without deflecting element is the sum of the smallest parallel to the ground surface aligned free cross-sectional areas of all openings without deflecting on a floor.
  • Different free cross-sectional areas of an opening may result, for example, if an opening is conical, so that it has a larger free cross-sectional area on the bottom of the bottom and a smaller free cross-sectional area on the top of the bottom or alternatively a smaller free cross-sectional area on the bottom Bottom of the soil and have a larger free cross-sectional area on the top of the soil. It is also possible that the free cross-sectional area of an opening initially decreases from bottom to top and then increases again.
  • the smallest free cross-sectional area of each opening is taken into account.
  • the free cross-sectional area of the openings without deflection element does not change over the thickness of the floor and thus the openings without deflection element have a constant free cross-sectional area.
  • the free cross-sectional areas of all openings on the floor must be taken into account. This is the sum of the free cross-sectional area of all openings without deflecting element on a floor and the smallest free cross-sectional area of all openings with deflecting element on the floor.
  • the smallest cross-sectional area of an opening with deflecting element is either the smallest free cross-sectional area of the opening parallel to the surface of the bottom, which is defined as in the openings without deflecting or the surface of all partial openings, each of the edge of the deflecting element and the edge of the opening be enclosed in the ground.
  • the number of partial openings, which are enclosed by the edge of the deflecting element and the edge of the opening in the bottom is dependent on the number of webs with which the deflecting element is fixed to the ground. With only one web is surrounded by the edge of the deflecting element and the edge of the opening in the bottom only a partial opening, two webs, however, already two partial openings are present.
  • the number of partial openings, which is enclosed by the edge of the deflecting element and the edge of the opening in the ground always corresponds to the number of webs with which the deflecting element is fixed to the ground.
  • the edge of the webs is in each case part of the edge of the deflecting element.
  • the sum of all partial openings, which are enclosed by the edge of a deflecting element and the edge of the opening in the bottom is the second free cross-sectional area of the opening with deflecting element.
  • the ratio of the smallest free cross sectional area to the total area of the bottom is in the range of 0.05: 1 to 0.3: 1.
  • the ratio of the smallest free cross sectional area to the total area of the bottom is in the range of 0.12 : 1 to 0.2: 1. Due to the corresponding ratio of the smallest free cross-sectional area to the total area of the ground, under normal operating conditions gene a mass transfer column a hold-up of the liquid on a soil, with a sufficiently long contact time of gas and liquid is achieved and at the same time the pressure drop over the height of the column is adjustable so that an economically meaningful operation is possible.
  • the second free cross-sectional area of an opening with deflecting element is 40 to 99% of the first free cross-sectional area.
  • the second free cross-sectional area is 60 to 95% of the first free cross-sectional area. Due to the lower second free cross-sectional area, the gas is accelerated as it flows through the opening with deflecting, so that in comparison to openings with constant free cross-sectional area with the same total gas volume flow uniform distribution of the gas flow to the second free cross-sectional area is achieved by the increased pressure drop.
