Claim:
1. A process for removing nitriles and/or pyrroles from a feedstream, the process comprising the steps of: (a) contacting at least one solvent with one or more adsorbents to remove contaminants of nitrogen and sulfur; and (b) contacting at least one feedstream comprising olefins, paraffins, and at least one of a nitrile and/or a pyrrole with the at least one solvent produced in step (a) to remove at least a portion of the nitrile and/or the pyrrole from the at least one feedstream to produce at least one treated feedstream which comprises less than 0.1 ppm of nitrogen and a contaminated solvent; (c) regenerating the contaminated solvent produced in step (b) by contacting the contaminated solvent with an inert gas to remove at least a portion of the nitrile and/or pyrrole to produce a regenerated solvent; and (d) recycling at least a portion of the regenerated solvent produced in step (c) to step (a).
