ABSTRACT:
A sour gas obtained from an enhanced oil recovery is converted to sulfur slurry which is concentrated for easy filtration, or for direct disposal, by the addition of substantially small amounts of a solid flocculating agent e.g. clay, optionally in combination with selected suitable conventional liquid polymer flocculants. For this purpose, bentonite has been shown to be a particularly effective solid flocculating agent.
