| 摘要 |
A system and process for the removal of divalent ions from a MEG-water stream (10) are presented. The system includes a chemical treatment tank (5) that receives the MEG-water stream (10), means for precipitating the calcium, magnesium, and hydroxide ions that are contained in the MEG-water stream (10), means for discharging the MEG-water stream (10) from the chemical treatment tank (5), and means for recycling the discharged MEG-water stream (10) back to the chemical treatment tank (5) or routing it to a solids removal system (75). The means for precipitating the calcium, magnesium, and sulfate ions may be employed simultaneously or sequentially. |
