Evaluating permeability of VOC and greenhouse gases in dense membranes: Insights from solubility parameters and basic molecular characteristics
Original language description
Benzene and its derivatives, emitted from printing ink and paint manufacturing sources, can be effectively captured using advanced membrane technologies. This study combines the experimental study on our unique home-made apparatus with theoretical predictions of gas and vapour permeability in polymeric membranes. The organic vapour permeability order was predicted primarily based on solubility parameters as the key factor for organic vapour transport in dense membranes. Low-permeability materials (polyethylene and polypropylene) and hydrophilic variants (polyvinyl alcohol and poly(ether-block-amide) copolymer Pebax® 1657) were tested, along with organophilic membranes (poly(ether-block-amide) copolymer Pebax® 2533 and polydimethylsiloxane) for model validation. The novelty is in predicting aromatic compound permeability from the knowledge of permeability of both greenhouse gas CH4 and other low-hydrocarbons and vice versa. The success of prediction depended on the selected basic molecular parameter. It was found that the permeability of lower alkanes, benzene and toluene exponentially increases with their critical temperature as the condensability parameter for polyethylene and polydimethylsiloxane membrane, respectively. The order of permeability was successfully predicted based on the solubility parameters for cyclohexane, benzene, and toluene for both organophilic membranes. Moreover, it was found that greenhouse gas CO2 permeability may be estimated from the light gases (helium and hydrogen) permeability in the relationship with their affinity based on the Hansen solubility parameters. These findings highlight the importance of both basic molecular characteristics and the interactions between the polymeric membrane and the permeating gaseous pollutants in selective gas capture.n
