| Research Abstract |
A novel method of thermally enhancement of membrane gas separation is proposed. A striking feature of the method is that it does not require any energy source except low-level temperature difference of few tens degree. The method also does not require any moving parts. This method is achieved by the use of 'molecular exchange phenomenon' of the rarefied gas, where a component gas of binary gas mixture flows in the opposite direction from the flows of the other component. The presence of this phenomenon is proved by the experiments in this study. A numerical method, pipe-net method, is developed; The pipe-net method can quickly reproduce the results of above experiments and DSMC simulation of Boltzmann equation. The numerical results by the pipe-net method show that the complete separation of binary mixture is possible by the present device. That is, the proposed device separates given gas mixture into two pure components.
