A European refinery faced a critical challenge: high concentrations of heat-stable amine salts (HSAS) and elevated formate levels, which led to corrosion, fouling, foaming, solvent losses, and operational instability in its sour gas treating unit.
Replacing the entire amine solvent inventory would have been costly and time-consuming, with additional complications for waste disposal.
Veolia delivered a Total Amine Solution featuring a custom-built mobile electrodialysis amine reclaiming unit, installed on-site with a dedicated power generator.
Thanks to this solution the entire operation was completed without impacting other refinery processes, and the effluent was safely routed to the wastewater treatment plant.
Results?
- Significant reduction of contaminants in the amine solutions
- 90% reduction in formate content
- Solvent losses limited to less than 1% wt
- Improved operational stability and corrosion control
- Over €400,000 in savings
