Abstract: A significant amount of the light olefins produced during the refining of crude oil is used as refinery fuel. As natural gas supplies in North America decline, the need to conserve and recover these olefins will become critical. Cost-effective separation technologies will be required that can withstand the harsh operating environment of a petroleum refinery. In addition to traditional refinery and olefin plant applications, paraffin dehydrogenation units for the production of olefins from natural gas liquids (NGL) have recently been brought on stream. Recent federal regulations mandate that hydrocarbon emissions from refineries and chemical plants be reduced to low levels. To reduce the economic penalty of environmental compliance, low-cost hydrocarbon separation technologies are required. For streams containing a mixture of paraffinic and olefinic material, economic and process considerations may dictate that the olefin be recovered and recycled. A review of traditional and nontraditional technologies for the separation of light olefins and paraffins is presented. The technologies addressed range from conventional low-temperature distillation to chemical complexation using copper and silver ions.

Facilitated transport in ion-exchange membranes
TL;DR: Ions were used as mobile, membrane-bound carriers for selected gas species, these being introduced as the counter ions in ion-exchange membranes as mentioned in this paper, which could be useful in practical gas separations, giving longer operating life under certain adverse conditions.
