Abstract
A process is provided for the selective removal of thiocyanate ions from a vanadium-containing loaded scrubbing solution used for oxidative hydrogen sulfide scrubbing. The thiocyanate ions are removed by means of an ion exchanger making reuse of the scrubbing solution possible. In this process, the ion exchanger can be loaded until the inlet and outlet concentrations of the thiocyanate ions are substantially the same.
