The Influencing Factors of Cl~- and Fe~(2+) Removed from Triethylene Glycol with Resin

The Cl-and Fe2+ in triethylene glycol were removed with ion exchange resin.It was investigated that operating capacity of the resin was influenced from water content in triethylene glycol,temperature,flow rate,concentration of the Cl-and Fe2+.The results showed that the operating capacity was improved with relationship of the water content increase,the flow rate decrease and temperature elevated.The operating capacity was few influenced when the concentration of Cl-was less than 4 000 mg/L,less than 100 mg/L of the Fe2+.
