摘要： Processes for removing heat stable amine salts from a contaminated aqueous amine solution are proposed comprising passing a feedstream of the contaminated aqueous amine solution in an electrodialysis zone comprising at least one repeat unit with an amine solution compartment for receiving the feedstream, a waste compartment, and an anion source compartment receiving an anion source stream or a bi-polar membrane disposed for providing anions balancing the heat stable anions. Monitoring of an anion source-related parameter being correlated to the anion source concentration of the anion-depleted source stream, or of a waste parameter being correlated to an acid concentration of the waste stream, is performed to further adjust an addition of the anion source or a removal of the waste stream in accordance with the monitored parameter.
