Opis:: The paper presents a pilot active membrane contactor system (AMCS) description and experimental results for air dehumidification. Triethyleneglycol was used as a hygroscopic liquid carrier. Polydimethylsiloxane based membranes (Lestosil) were used in a spiral wound membrane contactor. The experiments with AMCS demonstrated effective air-drying under a high ratio-feed gas flux/liquid carrier flux (10²-10³). The developed contactor system allows to achieve air dehumidification up to Tdew point= –20 °C.

Opis:: This paper is addressed to the membrane air separation i.e. the gas mixture of quite similar gases in many respects, except one: oxygen is paramagnetic whereas nitrogen is diamagnetic. This fact forms the basis for their separation. The numerical studies and theoretical predictions concerning the air membrane separation in the presence of a magnetic field are discussed. Some experimental data concerning the „magnetic membranes” i.e. ethylcellulose membranes with neodymium powder, are also presented.

Opis:: A zeolite membrane reactor concept for the hydroisomerization of n-hexane was applied experimentally. The results indicate separation selectivities with factors close to 20 for n-, mono- and dibranched components in a gas mixture, as well as nhexane conversions up to equilibrium values. The research octane number calculated for the product stream of the different experiments indicates numbers as high as 85. For the hydroisomerization of C7 alkanes, a concept of two reactors and a zeolite membrane was proposed and an industrial scale process was simulated. A high octane number product containing tribranched, and a part of dibranched, C7 isomers is predicted. Although the product yield was calculated to be only 24% of the process feed, there was an improvement in a research octane number from 57 for the feed to 92 for the product. Both processes show that the application of zeolite membranes in the hydroisomerization of light alkanes can results in a octane number higher, than in the "state of the art" processes. The membrane unit, however, is the main cost driver of the processes, thus, the economical feasibility of industrial scale light alkanes hydroisomerization processes using zeolite membranes is restricted to its further commercial development.
