    Abstract: The invention relates to a column (1) for thermally treating fluid mixtures, comprising a vertically aligned cylindrical column body (2) which forms a column cavity (3), a sequence of vertically spaced dual-flow material exchange bases (8) which are mounted in the column cavity (3) and which have openings for the passage of liquid and gas in counter-flow, and at least one gas inlet opening (5) which is arranged below the lowermost base of the sequence of dual-flow material exchange bases (8). The column according to the invention is characterized in that a gas distribution base (9) is arranged between the lowermost base of the sequence of dual-flow material exchange bases (8) and the gas inlet opening (5), said gas distribution base having openings (32) for the vertical passage of gas which can be introduced into the column cavity (3) via the gas inlet opening (5). The openings (32) are designed to cause a uniform distribution of gas over the column cross-section. The invention further relates to a method for thermally treating fluid mixtures in such a column (1).

    Abstract: The invention relates to a column (1) for thermally treating fluid mixtures, comprising a cylindrical, vertically-aligned column body (2) that forms a column cavity (3) and a vertical inner surface (16), a plurality of trays (8) which are mounted in said column cavity (3) and vertically spaced apart from one another, at least one neck (11) arranged in the column body (2) and extending away from said column body (2), and a closeable inspection opening (9) formed at the neck (11). The claimed column is characterised in that, in a vertical cross-section of the column (1), the surface (15) of the lower intersection line of the neck (11), directed into the column cavity (3), or a tangent to the surface (15) of said lower intersection line of the neck (11), forms, together with the vertical inner surface (16) of the column body (2) which extends downwards from said neck (11), an angle in the range of 210° to 267°, at least in some sections.

    Abstract: The invention relates to a method for recovering acrylic acid, having the following steps a) separating a temperature-controlled mother acid stream from a crystallization device in the direction of an absorption column (201) and in the direction of a splitting column (205), b) supplying the first temperature-controlled mother acid sub-stream as a return flow to the top plate of the splitting column (205), c) supplying at least one strip gas stream below the bottom plate of the splitting column (205), d) supplying an auxiliary component stream, which comprises an oligomeric acrylic acid, from the condensation column (201) to a central base of the splitting column (205), e) splitting at least one part of the oligomeric acrylic acid from the auxiliary component stream in the splitting column (205), thereby obtaining monomeric acrylic acid, f) separating the auxiliary components contained in the auxiliary component stream by means of a counter-current rectification process in the splitting column (205), g) discharging the monomeric acrylic acid without condensation as a gas mixture together with the supplied strip circuit gas stream at the head of the splitting column (205), and h) supplying the gas mixture below the bottom plate of the condensation column (201). The invention further relates to a system (1) for recovering acrylic acid.
