Definitions
- the invention relates to a continuous process for carrying out a reaction in which from a feed stream containing a continuous liquid phase, one or more liquid and / or solid phases are formed whose density is greater than the density of the continuous liquid phase of the feed stream, and a Use.
- the solution consists in a continuous process for carrying out a reaction in which from a feed stream containing a continuous liquid phase I, a liquid phase II whose density is greater than the density of the continuous liquid phase I of the feed stream, and optionally one or more solid phases, characterized in that the process is carried out in a hydrocyclone to which the feed stream, containing the continuous liquid phase I, is supplied tangentially, takes place in the hydrocyclone, the reaction to give a Reaction mixture containing the continuous liquid phase II, and optionally one or more solid phases which are formed in the reaction and wherein the reaction mixture is separated in the hydrocyclone under the action of centrifugal force, the shape that at the upper end of the hydrocyclone, a product stream withdrawn radially is containing a partial stream or the total flow of the continuous liquid phase II and all phases whose density is smaller than the density of the continuous liquid phase II and at the lower end of the hydrocyclone, a stream is withdrawn, all solid phases having a density greater than that Density of the continuous liquid phase
- hydrocyclones commercially available and correspondingly inexpensive devices can be used. In a known manner, these are apparatuses in the form of upright cylinders, which tend to taper conically at their lower end. While cyclones are operated with gaseous feed streams, the feed streams in hydrocyclones have a continuous liquid phase.
- the feed By supplying a feed stream via a tangential feed opening, in particular under pressure, the feed passes through the apparatus from top to bottom, whereby separation takes place on account of the differences in density under the effect of centrifugal force. Higher density phases are thrown to the periphery and accumulate on the periphery Inner walls of the apparatus and can be withdrawn through the outlet at the bottom of the often conical area. By contrast, phases of lower density remain in the center of the apparatus and can be drawn off via an opening arranged radially at the upper end thereof.
- the feed stream contains, in addition to a continuous liquid phase I, a gaseous and / or one or more solid phases.
- the feed stream containing a continuous liquid phase I is fed tangentially to the hydrocyclone, whereupon in the hydrocyclone the reaction takes place to form a reaction mixture containing a continuous liquid phase II whose density is greater than the density of the continuous liquid phase I from the feed stream ,
- all liquid and / or solid phases are separated whose density is greater than the density of the continuous liquid phase II of the product mixture, and subtracted at the lower end thereof.
- the apparatus is particularly suitable for working up of backflow, with liquid and / or solid components to be separated , for example, with rubber particles, are contaminated.
- the concentrated stream drawn off at the lower end of the hydrocyclone can be recycled again into the hydrocyclone, into the feedstream.
- the hydrocyclone may be heated or cooled.
- an outer sheath can be provided for receiving a heat carrier.
- the hydrocyclone may be equipped with devices for generating ultrasound.
- the feed stream may advantageously comprise water as the continuous liquid phase, a magnesium salt as the solid phase and carbon dioxide as the gaseous phase.
- the same can preferably be obtained in a concentration of between 1 and 3% by weight, more preferably between 1 and 2.5% by weight, preferably between 1 and 2% by weight, of magnesium hydrogencarbonate.
- the product stream may contain further solid and / or gaseous phases whose density is less than the density of the continuous liquid phase II (aqueous magnesium bicarbonate solution), in particular rubber particles.
- the feed stream is advantageously fed to the hydrocyclone under pressure, in particular at a pressure of up to 10 bar absolute, preferably between 1 and 6 bar absolute.
- a pressure of up to 10 bar absolute preferably between 1 and 6 bar absolute.
- the same reaction as in the hydrocyclone can first be carried out in a first process stage in a high-speed mixer, the reaction mixture withdrawn from the high-speed mixer being fed as feed stream to the hydrocyclone.
- the high-speed mixer thus has the function of a pre-reactor, wherein the reaction is driven to a certain conversion, which is lower than the residual conversion, which is achieved in the downstream process step in the hydrocyclone.
- This process procedure is particularly advantageous in equilibrium reactions with an initially steep increase in the reaction at the beginning of the reaction, which, however, flattens out considerably as the reaction progresses.
- Figure 1 the schematic representation of a hydrocyclone for use in a method according to the invention.
- the hydrocyclone (R) shown schematically in FIG. 1 has an upper tangential feed opening for a feed stream 1, a lower central draw opening for a stream 2 and an upper central draw opening for the product stream 3.
