Abstract
A system and process for removing divalent ions from a MEG feed stream is presented. The system includes a chemical treatment tank where chemicals are mixed with the feed stream to form insoluble carbonate and hydroxide salts. The system also includes a membrane-type solid-liquid separation unit that receives the feed stream from the chemical treatment tank and separates it into a filtrate containing MEG and a retentate containing the insoluble salts. The system may also include washing the retentate to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer that receives waste slurry from the solid-liquid separation unit and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal.
