DEVICE FOR MEMBRANE CONCENTRATION ETHANOL vapor phase from the aqueous-organic mixtures

摘要

The invention relates to the field of chemistry, namely, separation of liquid and vapor mixtures, and it can be used in various industries, agriculture and energy. The technical result - an increase selectivity evolution of gases from multicomponent gas mixtures of alcohols and dilute aqueous organic media of complex composition, preferably a fermentation medium while providing continuity of the process and low costs for manufacturing a membrane device. A device for membrane gas phase concentration of alcohols from aqueous-organic mixtures comprising membrane elements in the form of a disk, threaded through the hermetic ring collector for permeate, and placed in a sealed enclosure provided with an input for power, arranged before the first input disc element, and an outlet for retentate outlet arranged after the closing disc member, characterized in that the disk elements are unilateral ablation segment and assembled in a module with step-by Collar 60 °, while ethanol is the retentate and membrane are used as membranes polyvinyltrimethylsilane. 1 n.p.f. 1 z.p.f. 4-yl., 2 tab.
