ABSTRACT:
To improve the handling characteristics and dispersibility of a sulfur containing froth, especially a froth obtained from the regeneration step in a process for scrubbing out and oxidizing H.sub.2 S, there is added to the scrubbing liquor an ionic or non-ionic surfactant, e.g., dioctyl or dodecyl sulfosucciniate in sufficient concentrations, e.g., 3-16 ppm, to substantially prevent the sulfur particles from becoming crusty and stiff, this technique being particularly applicable to the replacement of diethanolamine.
