Definitions

  • the invention relates to a method for measuring the uniform filling of reactors or columns with solids and an apparatus for performing the method.
  • the uniform filling of reactors with solids is of crucial importance for the performance efficiency of the apparatus.
  • the solids are fillers or catalysts.
  • These solids can have different compositions and geometries. It can be balls, solid or hollow cylinders or rings, but other geometries are also possible.
  • the invention relates to a method for measuring the uniform filling of reactors with solids, the reactors being constructed in such a way that at least two separate gas and liquid streams with the same compositions flow through them, and the measurement is carried out in such a way that the filling with the solids
  • Tube reactors or reactors with reaction and heat transport spaces separated from one another by thermal sheets are particularly common as reactors.
  • the columns are, for example, absorption columns.
  • Inert gases air or mixtures thereof are generally used as gases.
  • the solid bed represents a resistance for the gas flow, through which the flow velocity is reduced and a back pressure builds up.
  • the volume flow of the gas should generally have a flow rate of 250 to 5000 l / h, the admission pressure of the gas should be in the range from 1 bar to 50 bar, in particular from 1 to 10 bar, and the temperature of the gas generally in the range of 10 up to 50 ° C. Inert gases, air or mixtures of these are ideally suitable.
  • a device with a structure as shown in Figure 1 is used, in which a corresponds to the number of parallel gas lines.
  • the dosage is considered constant if the
  • Flow rate of the gas fluctuates with less than +/- 2.5%, flow rates with a variation of less than or equal to +/- 1% are particularly suitable.
  • the dynamic pressure is advantageously measured in up to 15 parallel gas lines, in particular up to 10, particularly advantageously up to 5. Surrender different measured values, the filling with the catalysts used as solids, for example, is not uniform and must be improved.
  • the measurement of several gas flows possible simultaneously according to the invention enables a time-saving method for checking the filling of reactors.
  • a variance of up to + 5% is considered to be uniform.
  • the gas flow coming from the apparatus shown in Figure 1 is passed through the solid-state packing to be examined via an apparatus as shown in Figure 2.
  • the dynamic pressures generated are measured using a commercially available pressure transducer, for example from Ashcroft Inc., which is ideally mounted on the gas inlet device as shown in FIG. 2.
  • the pressure range of the transducer should range from 0 to 2500 mbar, but in particular from 0 to 1000 mbar.
  • the determined print data are forwarded to an electronic memory, which can hold up to 60,000 print data. This
  • Data storage should ideally be housed in a device with the pressure transducer.
  • the method is not limited to measuring the dynamic pressure as a measure of the flow resistance.
  • the gas flow can be measured as volume flow or mass flow. Brief description of the pictures
