APPARATUS FOR AZEOTROPIC EVAPORATION Russian patent published in 1996 - IPC

FIELD: apparatus is used in national economy fields, that use methods of azeotropic evaporation for processing, synthetic and analytic purposes, apparatus is used for organic solvents dewatering, lixiviation, dissolving, realization of synthesis with removal of formed during reaction water, determination of water share in studied substances samples. SUBSTANCE: apparatus for azeotropic evaporation has vertical settler-separator and cooler connected with evaporator by steam pipeline, and overflowing tube made in the form of siphon, one end of which is linked with settler-separator through multirun tap, The tube additionally has loop-shaped stopper of flow, one end of which is fixed to its discharge part and another one - to upper part of settler-separator. Apparatus has universal design: just tap turning provides capability to use solvents with their weight both lighter and heavier than water. Apparatus has higher effectiveness of azeotropic evaporation process, than others, and provides simplification of operations during process realization. EFFECT: increased effectiveness of process, simplification of its operations. 2 cl, 2 dwg, 2 tbl
