Definitions
- the suspension of the solid is carried out in a completely separated suspension process at low pressure.
- the solid is suspended in a non-critical and liquefied gas or partially dissolved.
- the pressure in this suspension process is less than 90% of the critical pressure of the liquefied gas.
- the entry of the suspension in the high pressure process by means of a pump.
- DE 199 28 405 is directed to a process for dyeing a textile substrate in at least one supercritical fluid, wherein a dosing is disclosed which divides the required amount of dye for the dyeing dye on a plurality of subsets and each dye subset for so long with the supercritical fluid in contact until it is dissolved or dispersed.
- the disclosed device provides an oscillating and two-sided piston, which is guided transversely to and through the process line of the critical fluid. This piston absorbs solid in one end position in a first bore, and in the other end position, this first bore is located in the main flow of the critical fluid, so that there the solid is washed out of the bore.
- a second bore is filled or emptied in reverse order at the other end of the piston.
- a disadvantage of the method presented in DE 19928405 and the device disclosed for this purpose is that the device must be designed and dimensioned for the same pressures as the main process. Furthermore, supercritical gas is trapped in the emptied and mainstream bore and guided into the filling position, so that either the same or a higher pressure must be present here or a relaxation takes place each time, which hinders the rapid filling process. that would. Another critical factor is certainly driving over a high-pressure seal with the bores guided through the piston. Damage to the sealing material and thus sealing problems are to be expected here after short periods of use. From WO 97/13915 a very common entry method for solids in ü berkritica process is described.
- the dye is provided in a dye formulation vessel which is located in a bypass to the main process.
- the corresponding valves are opened and the solids are entrained by means of a partial volume flow of the main process fluid.
- a constant dosage or targeted control of the dye supply is thus not possible because the fluid-solid mixture is diluted by the inflowing process fluid.
- all components of this by-pass method must meet the pressure and temperature requirements of the main process.
- a method optimized in comparison with the suspension method known from WO 97/13915 is described in US Pat. No. 6,261,326. In this method, an agitator is arranged in the dye-selling vessel for dissolving or suspending the solid or pumped by means of a pump, a subset in a circle.
- this preparation process there is a critical or an almost critical fluid state, since this preparation process from the main process, the treatment process, is supplied with supercritical fluid. As in the above-mentioned methods, this preparation method also suffers from the defect that it has to satisfy the high-pressure conditions of the main process, here called the treatment method. Furthermore, the entry of the solid, which is not shown in US Pat. No. 6,261,326, must take place via an expensive lock, or the solids feed containers must likewise be designed for the high pressure of the treatment process.
- the object of the invention was therefore to provide a suspension and solids introduction process which operates independently and more economically from the cycle of the high-pressure process than the processes from the prior art.
- the invention solves the problem by means of a method for suspension and
- This process represents a suspension stage of the high pressure Process is and is formed of a suspension tank and a device for fluid circulation and supply and discharge lines.
- the suspension container in a first step is filled with a solid and a fluid, wherein the fluid used is a liquefied gas which is in a non-critical state.
- the solid is suspended in the fluid by means of a fluid circulation device and kept in suspension.
- the liquid circulation device is ideally configured as a stirrer or as a pump arranged outside of the suspension container, which is connected via a suction and a pressure line to the suspension container and promotes a subset of the suspension continuously in a circle.
- the pressure in the suspension stage is advantageously less than 90% of the critical pressure of the gas used and is ideally less than 60 bar.
- the temperature is adjusted such that a gaseous phase is present above the liquid phase.
- the suspension is conveyed by means of a pump in the high-pressure process.
- a pump in the high-pressure process.
- the fluid used for the suspension is substantially chemically identical to the process medium of the high pressure process.
- the fluid is mixed with other substances.
- substances are, for example, cyclic and short-chain acyclic hydrocarbons or short-chain alcohols, aldehydes or ketones, and H 2 O and mixtures of these aforementioned substances.
- the pressure in the suspension vessel during the introduction of the suspension in the high-pressure process is kept constant in the inventive method by gas is nachge devist in gaseous state.
- the volume flow and thus the concentration of the solid in the fluid in a constant size or variable over the conveyor - power of the pump can be adjusted.
- the concentration in the suspension tank is substantially constant during the emptying, since the nachge deviste gas is not liquid, but is gaseous.
- the solid is a substance to be dissolved in the high-pressure process, such as, for example, dye particles, adhesion promoters, bleaching agents, flavors, odorous substances or mixtures thereof.
- an advantage of the invention is the fact that the solid is not dissolved as in the prior art, but only suspended and the specific solubility of the respective starting materials need not be met in the suspension stage. Rather, these substances dissolve in the introduction into the large volume flow of the main process due to the high concentration gradient directly.
- an advantageous embodiment of the invention is that the suspension stream is set at the initiation into the high-pressure process such that the ratio of the volume flows of suspension to Hochlichreamedi- to smaller than 1:50 and ideally equal to or less than 1: 100.
- the very low suspension flow in relation to the main process volume flow has a negligible physical influence on the main process as a rule.
- Fig. 1 shows the suspension process with a pump as wellsstechniksum stiilzaggregat and Figure 2 shows the method with a stirrer without external Ummélznikank.
- the suspension process 1 which is connected via the conduction path 6 with the high-pressure process 4, consisting essentially of the suspension vessel 2 and the pump 3 is formed.
- the suspension vessel 2 is filled via the conduit 7 with liquefied gas and via the conduit 8 with the solid.
- a liquid volume 2 a and a gas volume 2 b form in the suspension container 2.
- a further embodiment of the method can be seen, wherein in the suspension vessel 2, a stirrer 13 is arranged, by means of which the suspension is generated and kept stable.
