Abstract: The invention relates to a method for the transportation of a monomer composition in which a composition comprising an aqueous solution of partially or entirely neutralized acrylic acid or overneutralized acrylic acid is placed in a transport means or sent through a pipe. The method according to the invention is characterized in that it has an increased level of safety during the transportation of acrylic acid monomers, an improved quality of the resulting product, and a high degree of efficiency. The method ensures safe transport of the highly reactive acrylic acid. The amount of polymerization inhibitors added to said acrylic acid may be reduced. An additional advantage is the minimization of the formation of dimeric acrylic acid. Tempering of containers, pipes, and pipelines may be omitted.

Abstract: A process for the heterogeneously catalyzed gas-phase partial oxidation of an organic compound over a fixed catalyst bed present in a fixed-bed reactor having a plurality of catalyst tubes, in which the reduction of the quality of the catalyst load with increasing duration of operation is restored by a partial catalyst change, is described.

Abstract: Separating acrylic acid, contained as main constituent and glyoxal, contained as by-product from a gaseous product mixture of a partial gas phase oxidation of 3C-precursor compound of acrylic acid comprises producing a liquid phase containing at least 70 wt.% of acrylic acid and at least 200 mol.ppm of glyoxal in relation to the contained molar quantity of acrylic acid and separating glyoxal from the acrylic acid by crystallization from the liquid phase, where the acrylic acid is formed in crystallite form and the glyoxal is enriched in the mother liquor remained after crystallization.

Abstract: Target product continuous separating operation includes a heat exchanger having a secondary space and a primary space. The secondary space is separated from the primary space by a separating wall, which serves as a surface to transfer the heat from the secondary space to the primary space, where a current in fluid phase, and component of mass flow is fed to the target product in the secondary space of the heat exchanger. A fluid cooling medium having a temperature is fed to the primary space, such that fine crystals of the target product are formed in the secondary phase from the fluid residual phase of the fluid phase. A fluid cooling medium containing a mass flow is fed from primary space to the target product in a former operating state and in latter operating state. A fluid cooling medium containing another mass flow is fed from the secondary space to the target product. The liquid phase has the target product and different product, whose total mole fraction has a value in a component. The total mole fraction at the component, which is different from the target product, in the fluid phase fed in the secondary space, is bigger in the latter operating state than the former operating state.

Abstract: The procedure for continuous separation of target product (X) in the form of fine particle of crystallisate from a liquid phase (P) existing from the target product (X) and/or by the target product of different constituents, comprises indirectly operating a heat exchanger having primary and secondary areas, which are spatially separated with one another through a material divider that serves as an area for transmitting heat from the secondary area to the primary area by passing a stream at the liquid phase (P) in the secondary area of the heat exchanger. The procedure for continuous separation of target product (X) in the form of fine particle of crystallisate from a liquid phase (P) existing from the target product (X) and/or by the target product of different constituents, comprises indirectly operating a heat exchanger having primary and secondary areas, which are spatially separated with one another through a material divider that serves as an area for transmitting heat from the secondary area to the primary area by passing a stream at the liquid phase (P) in the secondary area of the heat exchanger during the primary area flows throughable simultaneously to a liquid cooling medium so that it forms fine particles of crystallisate of the target product in the secondary area under disposition of a liquid residual phase from the liquid phase (P). The total mole fraction of the liquid phase has the value of M b, p ges at the constituent (B i). The liquid residual phase (R) contains ingredients with a total mole fraction of M b, r (ges) greater than M b, p (ges) in comparison with the liquid phase (P). The content of residual phase in the target product is 70 wt.%. The cooling medium is suspended by fine particles of crystallisate of the target product in the liquid residual phase under receiving a suspension (S) having a crystallization grade (Y). The secondary area of the heat exchanger continuously takes the suspension with the temperature T s (aus). The suspension of fine particle crystallisate from the extracted suspension in load of discharge device is introduced with temperature (TS) to a mixing buffer container by a pump and the liquid phase is separated from the suspension contained in the discharge device. The temperature of the suspension in the buffer container is elevated from the way of secondary area in the buffer container and/or pipelines of the buffer container by external energy source at a value of T(pu) above of T s(aus) and/or the total mole fraction of the ingredients is increased in the liquid residual phase of the suspension in the buffer container through external additive in the ingredients at a value of M b, p u (ges) above of M b, r (ges). The T(pu)-T s(aus) is greater than or equal to 0.1 K. The increasing of M b, r ges at M b, r (ges) is greater than or equal to 0.1%. The content of the liquid residual phase at the target product is greater than or equal 90 wt.%. The crystallization grade (Y) is 0.20-0.40.

Abstract: The base (1) for a column to rectify or absorb thermally unstable materials, which tend to polymerize, has risers (7) with covering hoods (8) supported on struts (9). Collected liquid can also run off the edge of the base through outflows (6) from one or more gutters (5). The gutters are angled downwards towards the edge of the base by 0.2-5.0[deg] and preferably 0.5-2.0[deg], and the base surface is angled down towards the gutters by 0.5-5.0[deg] and preferably 1-3[deg]. The under side (2) of the base is flat and horizontal.
