    Abstract: Disclosed is a method for operating a hydraulic wash column, in which the position of the wash front in the wash column is determined by means of the rate of flow of the control liquor conducted into the wash column and/or by means of the rate of flow of the suspension conducted into the wash column, and the rate of flow is defined with the aid of the difference in pressure between points in the suspension zone located upstream of the wash front and points in the zone extending from the wash front to the end of the crystal bed in the column.

    Abstract: The invention relates to a multi-tube fixed-bed reactor and to the use of a reactor of this type for carrying out catalytic gas phase reactions, especially for carrying out exothermic or endothermic catalytic gas phase reactions such as producing phthalic anhydride (PSA), acrylic acid (AA), methacrylic acid (MAA), acrolein, maleic anhydride (MSA), glyoxal, phosgene, hydrogen cyanide or vinyl formamide (VFA). According to the invention, in the case of larger reactors where a considerable reaction heat is produced or required and must be dissipated as a result of the numerous reaction tubes (17), the ratio of tube distribution t to tube outer diameter d?a? is made dependant on the reactor diameter or the tube bundle diameter d?RBa?. If the outer diameter of the reaction tube bundle (18) is more than 4 metres, a ratio of tube distribution t to tube outer diameter d?a? of at least 1.3 is preferred.

    Abstract: In the production process for acrylic acid through catalytic vapour-phase oxidation of propene, acrylic acid is separated from the vapour-phase oxidation reaction mixture by means of an absorbing agent containing diphenyl, diphenyl ether or dimethyl phthalate and is also extracted from the vapour-phase oxidation acidic water by means of a solvent containing diphenyl, diphenyl ether or dimethyl phthalate.

    Abstract: Process for implementing a heterogeneously catalyzed partial gas phase oxidation of acrolein to acrylic acid or methacrolein to methacrylic acid in a solid catalyst bed comprises using a tube bundle reactor in reaction tube of a vertically arranged bundle of reaction tubes (9), which are closed by a reactor jacket; where: the both ends of the individual reaction tubes are open and each reaction tubes terminate with its upper end in a passage of a top tube plate sealed above in reactor jacket and with its lower end in a passage of a down tube plate (5) sealed below in reactor jacket. Process for implementing a heterogeneously catalyzed partial gas phase oxidation of acrolein to acrylic acid or methacrolein to methacrylic acid in a solid catalyst bed comprises using a tube bundle reactor in reaction tube of a vertically arranged bundle of reaction tubes (9), which are closed by a reactor jacket; where: the both ends of the individual reaction tubes are open and each reaction tubes terminate with its upper end in a passage of a top tube plate sealed above in reactor jacket and with its lower end in a passage of a down tube plate (5) sealed below in reactor jacket; the exterior of the reaction tubes, the top and the down tube plate, and the reactor jacket differentiate conjointly to the reaction tube surrounding chamber, and each of the two tube plates is spanned by at least a reactor cover (6) having an opening, with which, in order to set start-up in several respects, to the reaction tubes of the tube bundle reactor, at least an opening (3) in one of the both reactor covers supplies a reaction gas inlet mixture (1) containing >= 3 vol.% of acrolein or methacrolein and additionally molecular oxygen; at least an opening of the other reactor cover discharges by partial gas phase oxidation of the acrolein to acrylic acid or methacrolein to methacrylic acid, where the passage of the product gas mixture (2) containing acrylic acid or methacrylic acid results in the solid catalyst bed, which is present in the reaction tubes; at least a liquid heat exchange medium is supplied on the jacket side of the tube bundle reactor around the reaction tubes in such a manner that each of the two surfaces, which turned to each other, of the two tube plates is moistened by liquid heat exchange medium; the liquid heat exchange medium is inwardly introduced with a temperature T w(in) into the reaction tubes surrounding chamber and is outwardly emitted with the temperature T w(out) from the reaction tubes surrounding chamber; the temperature T w(in) of the liquid heat exchange medium, which moistens the tube plate spanned by the tube cover having the at least one opening, is at least 290[deg] C; the reaction gas inflow mixture entering into the opening has a temperature of = 285[deg] C, and the temperature of the surface of the reactor plate (4) turned to the reactor cover having at least an opening, has a value of = 285[deg] C.
