Abstract
Apparatuses, systems and methods for separating highly pure unsaturated olefinic hydrocarbon stream with zero cooling water and or steam consumption, with minimum possible capital investment and uncompromised operational ease are disclosed herein from a mixture of hydrocarbon stream consisting of saturated and unsaturated hydrocarbons. Embodiments of the invention are directed to producing a hydrocarbon stream containing polymer, chemical grade ethylene, propylene, butylenes, isoprene, hexane stream which are of value in manufacturing chemicals, polymers, and rubbers. Embodiments of the process provided can be applied to concentrating ethylene, propylene, butylenes, cyclopentadiene, isoprene, 2 methyl butene-2, isopentane, hexene etc.
