Abstract
A process is disclosed for separating diamondoid compounds from a natural gas stream containing the same comprising the steps of contacting the natural gas stream with a selected solvent and fractionating the sorbed diamondoids from the diamondoid-enriched solvent in a vacuum separation stage in the absence of reflux. Polyalphaolefin solvents are preferred, and polyalphaolefin solvents enriched in C.sub.30 oligomers are more preferred.
