Abstract
892,783. Liquid phase extraction. ALLMANNA SVENSKA ELEKTRISKA A.B. April 14, 1960 [April 15, 1959], No. 13304/60. Class 46. The extraction apparatus comprises a pulsed column 1. The lighter organic phase introduced at 3 is homogeneous and the transition zone consequently lies at the lower end 2 of the column 1, the heavy phase being introduced at 4. The outflow of the light phase occurs at 5 while the heavy phase leaves mainly at 6. The outflow of the heavy phase may, for example, take place with the help of a pulsing means 9 which is connected to the lower end of the column via a conduit 10. In this case a non- return valve 11 prevents the reflux and the regulation of the flow is carried out with the help of the valve 12, the liquid outflow taking place at 13. A pump can be used for this purpose. A cleaning circuit is connected to the lower end of the column at 14 which is in that plane at which the interface 15 is intended to be, and consists of a filter unit 16 and a level regulating device 17, the object of which is also to distribute the two liquid phases which are led through the filter unit. The device 17 consists of a cylindrical vessel 18 with a riser 19 for the lighter phase and a riser 20 for the heavier phase. The risers are provided with outlets 21 and 22, respectively, which are adjustable vertically. The outlets 21 and 22 are set at such a level that the phases reach the outlet level when the transition zone 15 in the column is at the level of the connection 14 of the branch conduit 23. At the level at which the branch conduit is connected, the column is provided with a guiding screen 24 which conducts the impurities from the transition zone towards the branch conduit. Fig. 2 shows another embodiment of the regulating device 25. Outlets 21 and 22 are at the liquid level reached when the transition zone 15 is at the level of the branch conduit 23. A guiding screen 24 directs the impurities from the transition zone to the branch conduit. Another similar cleaning device is illustrated in Fig. 2 (not shown).
