Currently, the separation of olefins (ethylene, propylene) from paraffins (ethane, propane) on a commercial scale is accomplished almost exclusively by cryogenic distillation in petrochemical industries and is considered highly energy intensive. Consequently, there is an enormous economic incentive...

Recent growth in the availability of domestic natural gas has led the industry to push for the development of liquefaction facilities, at both existing import/regasification facilities and new locations. As a consequence of this evolving need for North American liquefaction capacity, the Federal...
