Abstract (en)
[origin: WO02094432A1] The invention relates to a method for carrying out the distillation or reactive distillation of a mixture containing at least one toxic constituent, whereby the method is carried out in a column provided with an ordered packing comprising at least one packing layer (1), which has a lower end (2) and an upper end (3) as well as an inner dimension that varies over its height. The invention provides that during the distillation or reactive distillation, a spouted bed with a mainly dispersed gas phase can be controlled in a specific manner in a first lower area (6) of the packing layer (1) and, at the same time, a film flow with a mainly continuous gas phase can be controlled in a second upper area (7) of the packing layer (1).
