Abstract: Linear vibratory motion is imparted to two mutually opposite plates, which are connected to each other. As a result, conveying impulses are applied to solid particles. To permit chemical or physical processes to be carried out with fluids flowing in cocurrent or countercurrent streams and to effect a transfer of material or heat at a high rate during the vibratory conveyance or to disintegrate or compact the solid particles, conveying pulses are imparted to the particles by both plates and the solids occupy in a state of rest only part of the free space between the two plates.

Abstract: In a process of producing coarse pure potassium chloride crystals from feed solutions containing potassium chloride and other impurities, comprising cooling the solution under a vacuum in a plurality of stages connected in series, withdrawing by means of a conveyor the potassium chloride which has been crystallized in each stage, withdrawing the water vapors, collecting crystalline potassium chloride from the solution, drying the crystalline potassium chloride and separating the same into several fractions, compacting the fine fraction and cooling and aminating the end product, the potassium chloride content of the feed solution is increased in that potassium chloride from one or more of the stages containing solution at a low temperature is recycled to the feed solution before the latter enters the first stage. The temperature of the mixture of feed solution and recycled potassium chloride is maintained only slightly below the temperature of the feed solution, potassium chloride product is withdrawn at the desired rate from one or more of the stages which contain solution at a higher temperature, the vapors formed are withdrawn and are condensed by a direct or indirect cooling.

Abstract: Sponge iron is produced by a direct reduction with solid carbonaceous reducing agents. In order to permit a melting of the sponge iron, particularly of that part thereof which is inferior in metallurgical properties, in a process which is as simple and economical as possible, the exhaust gas from the direct reduction process is used to produce electrical energy, which is supplied to the electric reducing furnace, and sponge iron at a rate corresponding to the electrical energy that is produced is charged to the electrical reducing furnace and comprises at least part of the sponge iron which is inferior in metallurgical properties.

Abstract: The SO.sub.2 content of gases is catalytically reacted to form SO.sub.3. The SO.sub.3 -containing gases are cooled in a plurality of stages with a cooling fluid (A) before the SO.sub.3 is absorbed. The absorbing acid is cooled by a cooling fluid (B) which delivers heat to a consumer. To increase the temperature of the cooling fluid (B) or to reduce the expenditue and to prevent a temperature drop in the SO.sub.3 -containing gases below the dew point temperature, the SO.sub.3 -containing gases are cooled first by and indirect heat exchange and then by a second indirect heat exchange with a cooling fluid (A) to a temperature slightly above the dew point temperature of the SO.sub.3 -containing gases. The cooling fluid (A) is conducted in a closed cycle. The sulfuric acid circulated through the absorber is cooled by an indirect heat exchange with a liquid cooling fluid (B), which is conducted in a closed cycle. The liquid cooling fluid (B) which has been heated is heated further by an indirect heat exchange with the heated cooling fluid (A). The hot cooling fluid (B) is cooled by an indirect heat exchange with the consumer.

Abstract: In a process of regenerating laden absorbent solutions used to desulfurize gases which contain H.sub.2 S and CO.sub.2 and possibly COS, which solutions contain at least one highly volatile secondary amine in an organic solvent, the laden absorbent solution is flashed and stripped with its own vapor. The overhead vapors from the regenerator, which consists of an indirectly heated plate column, are cooled to approximately ambient temperature. The resulting condensate is separated and fed to the top of the regenerator. The cooled gas is withdrawn. A partial stream of the vapor is withdrawn from the regenerator 1 to 10 plates below the outlet for the overhead vapors and the inlet for the condensate and is cooled to ambient temperature. The resulting condensate is fed to the regenerator 1 to 10 plates above the inlet for the absorbent solution. The remaining gas is fed to a re-absorber, in which it is scrubbed in a counter-current operation with at least one partial stream of the absorbent solution, preferably with the effluent from the desulfurization COS. The exhaust gas is withdrawn from the top of the re-absorber. The absorbent solution drained from the re-absorber is fed to the upper portion of the regenerator. The regenerated absorbent solution is withdrawn and used to desulfurize gases which contain H.sub.2 S and CO.sub.2 and possibly COS.

Abstract: In gas-forming electrolyzers, particularly membrane electrolyzers having vertically extending plate electrodes, each electrode plate is divided into horizontal strips and the entire active electrode surface is parallel to the counterelectrode and spaced from it as closely as possible. The top portions of each of the horizontal strips into which the electrode is divided define gas escape paths and extend away from the counterelectrode. To improve the degassing of the electrolyte the ratio of the distance G between the counterelectrode or membrane and the gas-defining line S at the lower edge of each electrode strip to the distance E between the counterelectrode or membrane and the breakaway edge K of the angled portion defining the gas escape path corresponds to a degassing capability F which is lower than 0.6.

Abstract: Devolatilizable fine-grained material which contains hydrocarbons is devolatilized by means of fine-grained solids which have been heated to temperatures of about 500.degree. to 1000.degree. C. The devolatilizable fine-grained material is mixed with the heated solids and is thus heated to temperatures of about 400.degree. to 900.degree. C. The mixture is passed through a dwell zone, and gaseous and vaporous devolatilization products are withdrawn and cooled. The heated solids are fed to the dwell zone as a loosened stream in a trickling and/or agitated state of motion, and the devolatilizable fine-grained material is introduced into said stream in order to be admixed thereto. The heated solids and the devolatilizable fine-grained material can be mixed in a weight ratio of 3:1 to 12:1. The stream of trickling heated soids can be deflected at least in part.

Abstract: The gases are injected through double-tube nozzles which extend through the wall of the reactor into the molten bath. A cooling protective fluid is injected through one tube of each double-tube nozzle. To reduce or avoid a wear of the double-tube nozzles and the surrounding brickwork, the flow rate of the protective fluid is so selected in dependence on the composition of the slag and on the difference between the temperature of the slag and its solidification point that crusts will be formed on the nozzles but will not exceed a desired thickness.
