Electrodialysis-Effective Amine Reclamation with Minimal Operatioi Impact

摘要

The UCARSEPf process has been in commercial use for over 10 years as a method of removal non-regenerable salts from amine solutions. It has proven to be an economical and practical method of salt control. Process improvements over the years has resulted in improved performance and reduced amine losses. Electrodialysis is the only method of salt removal that does not have an impact on the operation of the amine unit. Amine is sent to the electrodialysis unit and is returned in exactly the same state except that the level of salts has been reduced. There is no need to modify the operation of the amine unit in any manner when the electrodialysis unit is on line. Recent developments have made possible the removal of salt with little or no neutralization of the amine solution. Electrodialysis units are also now available as fixed units for location that find it impractical to bring in the UCARSEP mobile unit.
