A review on olefin/paraffin separation using reversible chemical complexation technology

In the present work, the facilitated transport membrane (FTMS) technology used in separation of olefins from paraffins is reviewed. Primary attentions are given to basic fundamentals, advantages and methods of facilitated transport membrane technology. The general mechanisms by which the facilitated transport proceeds under various conditions are described. The effects of different parameters on the degree of facilitated factor, permeance, and selectivity in the FTMs are thoroughly discussed. The performance of the membranes and its current application related with the polymer, solvent, and carrier structure developing during membrane preparation are also considered. A number of potential applications of the FTMs in a variety of modules can be added and optimized in a process design to achieve the desired separation are highlighted in this review. Finally, some reviews have been conducted for the modeling as well as the numerical solution to the governing system of equations. (C) 2008 The Korean Society of Industrial and Engineering Chemistry.
