INVENTOR: SAMUEL L. BEAN TITLE: IMPROVEMENT AND PROCESS FOR MAKING SODIUM METABISULFITE ABSTRACT OF THE DISCLOSURE Improvement in the process for making sodium metabisul- fite by contacting a suspension of sodium carbonate in countercur- rent stream with sulfur dioxide, which involves passing sulfur dioxide-containing gas sequentially through a first and a second reaction vessel, maintaining an acidic aqueous slurry of sodium metabisulfite in the first reaction vessel and a strongly alkaline aqueous slurry of sodium carbonate in the second reaction vessel, continuously feeding sodium carbonate to the second reaction vessel, passing strongly alkaline slurry from the second reaction vessel to the first reaction vessel and overflowing excess liquid from the first reaction vessel to the second reaction vessel, and recover- ing sodium metabisulfite crystals from the slurry in the first reaction vessel.
