摘要
进行了一次赤泥洗液铝酸钡脱硫试验研究,采用"氧化铝浓度法"测定碳碱的变化,引入氧化铝回收率作为脱硫过程的经济指标,考察了脱硫剂浓度、温度和时间时脱硫效果的影响。结果表明,脱硫时间10 min、脱硫温度60℃、脱硫剂添加量60%时,氧化铝回收率最佳。
The test on desulfurization of first red mud washing liquor with barium aluminate was performed. The changes of carbon dioxide-soda was determined with alumina concentration method, the alumina recovery rate was taken as an economic indicator for the desulfurization process to test the influence of desulfurizing agent concentra- tion, temperature and time on desulfurization effects. And the test results showed that the optimal alumina recovery rate was realized when the desulfurization time is 10 min, at 60 ℃, and the addition amount of desulfurizing agent was 60%.
