  • 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.

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.

Abstract

La présente invention concerne un procédé pour mettre en suspension et introduire une substance solide dans un processus haute pression, par exemple des pigments colorés dans un processus haute pression dans lequel un liquide surcritique est utilisé comme substance de processus et une pression de plus de 150 bar règne. Selon l'invention, la mise en suspension de la substance solide est réalisée à basse pression au moyen d'un procédé de mise en suspension complètement séparé. Dans le cadre de ce procédé de mise en suspension, la substance solide est mise en suspension ou partiellement dissoute dans un gaz non critique liquéfié. La pression au cours de la mise en oeuvre de ce procédé vaut moins de 90 % de la pression critique du gaz liquéfié. L'introduction de la suspension dans le processus haute pression s'effectue au moyen d'une pompe.
