Zusammenfassung:	The present disclosure relates to processes for the removal of paraffins. The processes generally include providing a C4 containing stream including isobutylene, 1-butene, 2-butene, n-butane and isobutane, introducing the C4 containing stream into a paraffin removal process to form an olefin rich stream, wherein the paraffin removal process is selected from extractive distillation utilizing a solvent including an organonitrile, passing the C4 containing stream over a semi-permeable membrane and combinations thereof; and recovering the olefin rich stream from the paraffin removal process, wherein the olefin rich stream includes less than 5 wt. % paraffins.
