    Abstract: The invention relates to a reactor (R) for performing a three-phase reaction of a fluid phase (1) and a gaseous phase (2) on a packed bed catalyst (F), the packed bed catalyst (F) being disposed horizontally in the reactor (R) and the fluid phase (1) and the gaseous phase (2) being fed through the reactor (R) from the bottom to the top, using a mixing and distributing device (MV) across the packed bed catalyst (F), characterized in that the mixing and distributing device (MV) comprises a trough distributor (TV) for the fluid phase (1) having trough-shaped channels (K) and drain tubes (A) in the trough-shaped channels (K) for the fluid phase (1), and a distributor floor (B) disposed below and at a distance from the trough distributor (TV) in which vertical spouts (T) are disposed, having one or more openings (P1) for the inlet of the gaseous phase (2) and one or more openings (P2) disposed below the openings (P1) for the inlet of the gaseous phase, for the inlet of the fluid phase (1) into the spouts (T), and the number and size of the openings (P2) for the inlet of the fluid phase (1) being designed such that the fluid level on the distribution floor (B) is adjusted to be below the openings (P1) for the inlet of the gaseous phase (2) and above the openings (P2) for the inlet of the fluid phase (1) for a prescribed inlet flow of fluid.

    Abstract: The invention relates to a base for a mass transfer column, comprising gas through-openings which are distributed over the base (1) and at least one baffle plate (11) for directing the flow of liquid flowing on the base, said base (1) being loadable with a liquid via at least one inlet (3). The base has at least one inlet (3), at least one separating weir (5) which separates the inflowing liquid into two flows, and at least two outlets (12) or at least two inlets (3) and at least one outlet (12) for the liquid. Each flow flows along a flow path (7; 9) to an outlet (12). The invention further relates to a mass transfer column which contains the base and to a use of the base and the mass transfer column.

    Abstract: The invention relates to a tray for a mass transfer column, having gas passage openings distributed over the tray (1), and having at least one baffle (11) for flow diversion of liquid flowing on the tray, it being possible for the tray (1) to be fed with a liquid via at least one entry (3). The tray has at least one entry (3), at least one separating weir (5), which separates the inflowing liquid into two streams, and at least two exits (12), or has at least two entries (3) and at least one exit (12) for the liquid, each stream flowing along a flow path (7; 9) to an exit (12). The invention further relates to a mass transfer column comprising the tray, and to a use of tray and mass transfer column.

    Abstract: Process for the preparation of on-spec phthalic anhydride by the distillative purification of crude phthalic anhydride at reduced pressure, where the crude phthalic anhydride is passed to the distillation column above a side take-off, the low-boiling components are removed at the top of the column or in the vicinity of the top of the column and the on-spec phthalic anhydride is removed from the side take-off of the column, in which a distillation column is used whose number of theoretical plates located above the supply of the crude phthalic anhydride into the distillation column is 10 to 20 and the column is operated at a reflux ratio of from 0.1 to 0.5.
