Summary:A system and process for removing hydrocarbons from a gas process feed stream is presented. The treatment process may be, but is not limited to, glycol dehydration, amine sweetening, and MEG reclamation. As an example, a hydrocarbon removal bed (25) containing a solid adsorbent material adsorbs the hydrocarbons in a rich MEG feed stream (20) as it passes through the hydrocarbon removal bed. After the hydrocarbons have been removed, the feed stream flows through a flash separator (35) and a distillation column (50) to reclaim MEG. Alternatively, the hydrocarbon removal bed (25) may be used after the MEG reclamation process to remove hydrocarbons in the distilled water from the distillation column (50). Spent solid adsorbent material may be regenerated in place.
