Abstract: A REACTOR APPARATUS COMPRISES AT LEAST TWO SAME-TYPE TUBULAR REACTORS WHICH ARE FILLED WITH SOLID PARTICLES, AT LEAST ONE TUBULAR REACTOR CONTAINING A TEMPERATURE MEASURING UNIT, THE TUBULAR REACTORS BEING DESIGNED SUCH THAT BOTH THE RATIO OF THE MASS OF THE SOLID PARTICLES TO THE FREE CROSS-SECTIONAL AREA OF THE RESPECTIVE TUBULAR REACTOR AND THE PRESSURE DROP MEASURED BY AN INERT GAS BEING CONDUCTED TRANSVERSELY TO THE FREE CROSS-SECTIONAL AREA ARE IDENTICAL ACROSS THE RESPECTIVE TUBULAR REACTOR. THE APPARATUS IS SUITABLE FOR TREATING FLUID MASSES WHILE GENERATING OR CONSUMING THERMAL ENERGY, THE TEMPERATURE BEING MEASURED.

Abstract: In the present invention, there is described a process for the catalytic gas-phase oxidation of acrolein to acrylic acid in a multiple contact tube fixed-bed reactor through whose space surrounding the contact tubes only one heat-exchange medium circuit is passed, at elevated temperature on catalytically active multimetal oxides with an acrolein conversion for a single pass and an acrylic acid formation selectivity, which comprises firstly passing the heat-exchange medium through the multiple contact tube fixed-bed reactor longitudinally, considered over the reaction container as a whole, to the contact tubes in co-current to the reaction-gas mixture and secondly superposing a transverse flow within the reaction container by means of an arrangement of successive baffles along the contact tubes which leaves passage cross sections free, so as to give a meandrous flow of the heat-exchange medium, seen in longitudinal section through the contact tube bundle, and setting the flow rate of the circulated heat-exchange medium so that its temperature rises by from 2 to 10 degC.

Abstract: Reactor arrangement comprises at least two tubular reactors filled with solid particles, at least one reactor containing a temperature measuring device. The novelty is that the tubular reactors are arranged so that the ratio of the composition of the solid particles to the free cross-sectional surfaces of each reactor as well as the pressure loss, measured by passing an inert gas proportionally transversal to the free cross-sectional, are equal over each tubular reactor. Also claimed is a process for treating fluid compositions with the production and consumption of thermal energy using the above reactor arrangement.

Abstract: Gas coolers in which hot gasses are brought into contact with a moving cooling liquid film are used for cooling hot gasses and thus for preventing the formation of condensation cores. In a process for cooling hot gaseous reaction products from gas phase reactions for preparing glyoxal of compounds of general formula (I): H2C=C(R )-C(R )=O, in which R is hydrogen or methyl and R is hydrogen or OH, in particular acrolein, methacrolein, acrylic acid and methacrylic acid, hot gaseous reaction products are brought into contact with a cooling liquid in a gas cooler, and the cooling liquid is present in the form of a moving liquid film.

Abstract: In the sepn. of (meth)acrylic acid (I) from mixts. by rectification, in which (I) is discharged from the column at a point higher than the inlet for the mixt., the refluxing liq. is removed in at least one position of the column, the oligomerised and/or polymerised (I) is sepd. and the liq. is recycled to the column.
