Estimating the term…
The invention relates to a process for the electrolytic dissociation of hydrogen sulfide dissolved in an amine scrubber solution in an electrolysis cell (11) which has an anode space (9) and a cathode space (15), with the anode space (9) and the cathode space (15) being separated by a membrane (13), in which at least one supporting electrolyte is added to the amine scrubber solution, an anion-conducting membrane is used for separating anode space (9) and cathode space (15) and/or the amine scrubber solution in which the hydrogen sulfide is dissolved comprises at least 10% by volume of potassium N,N-dimethylaminoacetate. The invention further relates to a use of the process.
