A liquid redistributor, arranged in a packing column between two packings, wherein in the column a liquid phase is guided from top to bottom and against the same a gas phase from bottom to top, comprising a liquid distributor tray and a droplet damping tray, which attenuates the fluidization of the liquid layer on the liquid distributor tray as caused by the droplets falling down.

Liquid redistributor

A distillation column with external circulation evaporator and a sedimentation zone in the bottom of the column, from which the evaporator circulation is fed, and use of the distillation column for the distillation of acrylic acid.

A continuous process is disclosed for the extraction of monomeric caprolactam and its oligomers as the raw polymer product obtained in the polymerization of polyamide-6 in which no fresh water, but processing water or previously used extraction water is used for the granulation.

Continuous process for the extraction of polyamide-6

The invention relates to a continuous or discontinuous method for the production of highly condensed polyesters in the solid state, comprising a crystallization of a polyester material, wherein the crystallization is carried out in the presence of a gas with a dew point of (less than or equal to) &#x2266;approximately &#x2212;10&#xb0; C. The invention also relates to a method for the production of polyester formed bodies using the polyester material obtained for the production of bottles, films and high strength threads.

Method for producing highly condensed solid-phase polyesters

Thermoplastic polyesters are made by a method in which precondensation is carried in a column whose sections are formed with structured packings and operated at subatmospheric, pressure.
