Zusammenfassung:	Processes utilizing the integration of (i) processes and the associated equipment used to purify and recover propylene from propane- and/or C4+-containing refinery hydrocarbon streams, with (ii) catalytic dehydrogenation are disclosed. This integration allows for elimination of some or all of the conventional fractionation section of the dehydrogenation process, normally used to purify propylene from unconverted propane in the reactor effluent. Significant capital and utility savings are therefore attained.
