Controlling the impurities in gas treatment units at refineries, natural gas processing and syngas plants.

Anionic impurities in amine scrubbing solution cause formation of amine Heat Stable Salts (HSS). Increased concentrations of HSS disrupt amine unit operations, cause excessive foaming and corrosion, increasing amine losses and filter replacement frequency. The Eco-Tec AmiPur system using Recoflo® ion exchange technology, continuously removes Heat Stable Salts from amine solutions. Continuous removal of HSS allows for consistent performance of amine units under optimal conditions with minimal attention. Low HSS content has shown to dramatically reduce corrosion, thereby extending the life of process equipment and reducing maintenance and filter replacement requirements.
