Measurements on the Flow of Vapors near Saturation Through Porous Vycor Glass Membranes
Original language description
We present experimental data of the flow of butane and isobutane vapors through porous Vycor glass membranes. The pressure driven flow of vapors near and far from saturation through membranes with pore diameters of 20 and 33 nm is investigated. The upstream pressures lie between the saturation pressure at the upstream temperature to approximately half that value. The pressure differences are between a few kPa to about 100 kPa.Describing the flow in terms of dimensionless groups recovered from an adiabatic description of the flow process, we find that a vapor condenses and the mass flux is increased if (i) a dimensionless permeability of the membrane is larger than one and (ii) if the vapor at the upstream side is close enough to saturation such that adimensionless group involving the upstream pressure and the pressure difference is also larger than one. Experimental data corroborates condition (i) above and indicates that condition (ii) might be valid.
