ABSTRACT:
A process is disclosed for removing and recovering from gas streams the sulfur values of dilute concentrations of sulfur vapor, hydrogen sulfide, and sulfur dioxide which are not recoverable by previously known methods. The gas streams are scrubbed with aqueous suspensions of solid catalytic material which precludes formation of collodial sulfur in the aqueous suspension and collects the sulfur values as solid sulfur deposit, which is recovered during restoration of catalytic activity of the solid catalytic material.
