FIELD: chemistry.SUBSTANCE: group of inventions relates to devices for separating volatile substances. Selective membrane element for separation by means of evaporation of volatile substances, deposited on it, comprises sheet material and deflectors, formed on or in material sheet. Deflectors form trajectory of minimum length on sheet for volatile substance, passing along it between at least part of first edge and opposite second edge sheet, wherein minimum trajectory length exceeds length between first and second edges along sheet surface. Group of inventions also refers to secretory device containing above membrane element.EFFECT: group of inventions increases compactness secretory membrane element at simultaneous increase of volatile substance evaporation time.18 cl, 12 dwg, 1 tbl |
