    摘要: A filter element for end face inlet formed of triangular channels which are alternately closed such that the fluid to be filtered must pass through the filter material in order to flow from the inlet side (22) to the discharge side (23). The channels are formed by alternating flat layers (17) and folded layers (18), whereby all sides of the inlet channels face a discharge channel. A particularly high filter efficiency is thereby achieved such that a large filter surface area and a high filter capacity are attained with a relatively small structural volume. The filter can be used, for example, as an air filter for various air filtration applications.

    摘要: A process for the continuous distillation of thermolabile monomers under reduced pressure in a column includesfeeding the thermolabile monomers in vapor or liquid form to the column,introducing an inert distillation aid which forms a heteroazeotrope with the thermolabile monomers into the vaporizer at the bottom of the column, but separately from the monomer feed, and vaporizing into there or feeding an emulsion of thermolabile monomers and an inert distillation aid into the vaporizer or into the column,condensing the azeotrope at the top of the column and separating it in a phase separator, taking off the thermolabile monomers and returning the distillation aid to the column or, if desired, working it up by distillation andtaking off components having a higher boiling point than the thermolabile monomers from the bottom of the column.
