Concentration and purification method and device for organic liquid solute
专利汇可以提供Concentration and purification method and device for organic liquid solute专利检索，专利查询，专利分析的服务。并且PURPOSE: To provide organic substance of high purity out of organic water solution and the like in an effective and energy-saving way by lowering the density of a second solvent extracting organic liquid solute selectively and carrying out phase-separation of organic liquid solute from the second solvent.
CONSTITUTION: A raw material mixture of organic liquid and a first solvent from a supply line 1 or the middle section, and a second solvent from a supply line 2 of the lower section are supplied to a countercurrent contact extraction device 3 consisting of a shelf 4 as the upper section and a filling material layer 5 as the lower section, and the second solvent under super-critical state or pseudo-critical state is countercurrent contacted in the filling material layer 5. Then, light liquid of an extraction line 7 is decompressed with a pressure reducing valve 8 or heated up a heat exchanger 9 for heating, and led into a separation tank 10, phase-separated into second solvent and purified organic liquid solute. Then, said purified organic liquid solute is extracted out of an extraction line 11, part of which is flowed back to the upper section of the extraction device 3 through a reflux line 13.
