Abstract

A novel composite hollow fiber membrane has been developed for the separation of C2+ hydrocarbons from their mixture with methane. A high-performance porous polysulfone hollow fiber support was fabricated. Polydecylmethylsiloxane (PDecMS) and polydimethylsiloxane (PDMS) were used as a thin selective layer. Comparison of the results of separation of binary mixture of CH4 and C4H10 using PDecMS/PSF and PDMS/PSF membranes showed that for the PDecMS/PSF module the specific retentate flux and n-butane concentration in the permeate are 1.7 times higher and energy consumption is 9 times lower.
