Abstract A system and process for removing hydrocarbons and divalent cations from a rich MEG feed stream (20) is presented. A hydrocarbon removal bed (25) containing a solid adsorbent material adsorbs the hydrocarbons in the rich MEG feed stream (20) as it passes through the hydrocarbon removal bed (25). After the hydrocarbons have been removed, the rich MEG feed stream (20) flows through an ion exchange bed (90) containing an ion exchange resin in order to remove divalent cations. The rich MEG feed stream (20) then flows through a flash separator (35) and a distillation column (50) to reclaim MEG. Spent solid adsorbent material in the hydrocarbon removal beds (25) and spent ion exchange resin in the ion exchange beds (90) may be regenerated in place using by-products of the MEG reclamation process.
