Abstract(#br)Vapor permeation through dense membrane is regarded as an effectively way to separate volatile organic compounds (VOC) from industrial gas stream. This study proposes a new method to get the solubility and diffusivity of pure VOC vapor in dense membrane. C 5 H 12 , C 6 H 14 and C 7 H 16 were selected as sample VOC components to conduct newly developed sorption experiment with polydimethylsiloxane (PDMS) membrane.

Abstract(#br)The solubility and diffusivity of several liquid species in crosslinked polydimethylsiloxane (PDMS) films were determined with a gravimetric method at 35\u003cce:hsp sp=\"0.25\"/\u003e°C. The series of liquids considered includes alkanes (from n-C 5 to n-C 18 ; cyclo-C 6 ), water, acetone, alcohols (ethanol, 1-propanol, 1-butanol, iso-butanol, tert-butanol, 1-pentanol, 1-hexanol), terpenes (squalene, limonene, linalool, geraniol) and edible oils with different oleic acid contents.
