The formation of heat stable salts (HSS) is a tough problem for aqueous alkanolamines solution in gas processing industry. In this study, a self-made electrodialysis stack was assembled to remove the HSS from spent amine wastewater. Results indicated that the optimum current density is 15 mA/cm2. An increase in pH is beneficial for amine recovery but is harmful to the lifespan of membranes. The ED process cost is estimated to be 14.6 $/t with the energy consumption of 39.4 kWh/T. Comparison with the conventional neutralization or replacement methods, ED is not only energy-saving but also environmentally friendly for the removal of HSS from the spent amine wastewater.
