Separation Of Ethylene From Ethane By Supported Liquid Membranes Containing Silver Nitrate As A Carrier

Abstract

Experimental results for the facilitated transport of ethylene through supported liquid membranes containing silver nitrate as a carrier are presented. The selectivity factor in the separation of ethylene and ethane increases with increasing carrier concentration, reaching about 1000 when silver nitrate concentration is 4mol/dm3. An approximation method for calculating the rate of facilitated transport accompanied by an instantaneous reversible reaction is proposed. This method is applicable even to the case where the diffusivities of the carrier and the complex differ from each other. It is found that the effect of experimental condition on the permeation rate of ethylene is satisfactorily explained by assuming that the reaction between ethylene and Ag + is instantaneous and reversible. © 1986, The Society of Chemical Engineers, Japan.
