| Abstract |
The New Jersey Zinc Company process for acid recovery employs spray evaporation to separate sulfuric acid from metallic sulfates. The salts are removed as dry, free-flowing solids and the acid-laden off-gas is directly cooled to partially condense product acid having a concentration in excess of 85% H2SO4. The process was piloted at Palmerton, Pennsylvania, at a rate of two tons per day of sulfuric acid (100 percent basis) using as feed the waste stream of a titanium dioxide pigment plant. On the basis of the pilot work, a commercial plant was designed to process 345,000 metric tons annually of 19.5 percent H2SO4 waste end liquor from a 38,100-metric-ton-per-year pigment plant. The estimated investment (as of January 1, 1975) is $7,800,000. Operating costs (including depreciation at 10 percent) would be approximately $77 per metric ton of 100 percent H2SO4 recovered. This cost includes neutralization of the dried solids and disposal in a landfill site. |
