Salt removal from rich MEG
Salt removal from rich MEG
(OP)
We are doing some work for a client, converting an existing TEG regen unit to MEG service. Due to the salinity of the produced water, the Rich MEG to be processed has a high salt content (of the order of 12,000 ppm TDS). The concern is that the salt will deposit on the tubes of the reboiler tube bundle as the water evaporates and result in scale fouling. The reboiler has not been designed to be pulled apart easily for cleaning, due to the elevation and the small area between the tubes. Does anyone know of a cost effective method for reducing the salinity of a rich MEG stream that could be applied upstream of the reboiler.
Thanks

I have also been looking into High Efficiency Electrodialysis (HEED) that a compnay called EET Corp (http://www.eetcorp.com)has. They claim it is more cost effective than Vac distillation, ion exchange or RO.
