Abstract

The permeability, solubility, and diffusivity of n-C₄H₁₀/CH₄ mixed gas in vapor selective polymers at -20°-50°C are presented. The dilation isotherms are also presented to complement the mixture sorption data. In rubbery poly(dimethylsiloxane), the presence of larger, more condensable n-C₄H₁₀ considerably improved the CH₄ solubility, permeability, and diffusivity in the polymer. On the other hand, the n-C₄H₁₀ sorption and transport properties in mixtures were unaffected by the presence of CH₄ and were similar to those observed under pure gas conditions. The overall n- C₄H₁₀/CH₄ permeability selectivity in mixtures increased as n- C₄H₁₀ activity increased and as temperature decreased, and the selectivity was lower than that estimated from pure gas measurements. The overall selectivity in PDMS was governed by solubility selectivity. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).
