| 摘 要： | 2013年云南省硫酸总产量(以H2SO4计)为13.19 Mt,其中硫磺制酸产量为9.19 Mt,冶炼烟气制酸产量为2.30 Mt,硫铁矿制酸产量为1.70 Mt;2010—2013年云南省硫酸产量年均增长率为6.7%。2013年云南省磷复肥消耗硫酸11.34 Mt,约占硫酸总产量的86%;饲料级磷酸钙消耗硫酸1.60Mt,约占硫酸总产量的12%。2013年云南省磷肥总产量(以P2O5计)为4.53 Mt,创历史新高。其中高浓度磷复肥产量在磷肥总产量中占比稳定在84%以上。针对云南省硫酸生产存在的问题提出了建议,并预测磷肥生产发展趋势。

| Abstract: | Production of sulphuric acid increased by 6. 7% to 13.19 Mt （as H2SO4） in Yunnan Province in 2013, with 9. 19 Mt from sulphur, 2. 30 Mt from metallurgical off-gas, 1.70 Mt from pyrite. Phosphate and compound fertilizer consumed 11.34 Mt of sul- phuric acid, accounting for 86% of sulphurie acid production, and feed grade calcium phosphate consumed 1.60 Mt of sulphuric acid, accounting for 12% . Production of phosphate fertilizer in 2013 increased to 4. 53 Mt（ as P205 ） , reaching a new record, with high concentration phosphate and compound fertilizer steadily accounting for more than 84% of phosphate fertilizer production. Proposals on problems of sulphuric acid production in Yunnan are made, and development trend are forecasted. |
