Title: Separator for multi-stage liquid extractor - having perforated plates on pure liquid streams to prevent re-entrainment
Inventor: EISENLOHR KARL-HEINZ DR ING
IPC: B01D11/04
Filed: 1974-05-29
Abstract: Multi-stage liquid-liquid extractor consists of a series of extraction stages mounted one above teh other as described in the parent patent. Each stage has a liquid separator between it in which the separated pure phases pass through a perforated surface which contains holes with dies from 3-20 mm, pref. 5-15 mm. The holes are uniformly distributed across the surface but the spacing need not be the same on the upper and lower surfaces. Towards the horizontal centre of the separator, the hole spacing can be increased. The surface should be inclined in the range 5-45, pref. 10-25 degrees, to the pure liquid level. The perforated surfaces reduce liquid entrainment and mean either that the effective throughput of the extractor is increased, or if separation is improved, the efficiency of extraction is improved and therefore less of the extracting phase can be used.
