DIVALENT ION REMOVAL FROM MONOETHYLENE GLYCOL (MEG) FEED STREAMS. |
摘要 |
A system and process for removing divalent ions from a MEG feed stream (15) is presented. The system includes a chemical treatment tank (25) where chemicals are mixed with the feed stream (15) to form insoluble carbonate and hydroxide salts. The system also includes a membrane-type solid-liquid separation unit (60) that receives the feed stream (35) from the chemical treatment tank (25) and separates it into a filtrate (90) containing MEG and a retentate (130) containing the insoluble salts. The system may also include washing the retentate (130) to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer (140) that receives waste slurry (132) from the solid-liquid separation unit (60) and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal. |
