摘要
介绍了2011年我国硫酸磷肥生产运行情况。2011年我国硫酸总产量(以H2SO4计)79 738 kt,同比增长8.0%,其中硫磺制酸产量38 441 kt,冶炼烟气制酸产量21 297 kt,硫铁矿制酸产量19 691 kt,其他原料制酸产量309 kt。磷肥总产量(以P2O5计)16 412 kt,同比增长3.7%;其中高浓度磷复肥产量14 126 kt,同比增长8.5%,占全国磷肥总产量的86.1%。全年进口硫磺9 523 kt,同比下降9.3%;进口硫酸1 110 kt,同比下降31.1%,其中韩国硫酸约占72.2%,日本硫酸约占27.0%。预计2012年我国硫酸磷肥将保持微弱增长的运行态势,总体形势较为严峻。
China＇ s sulphuric acid and phosphate fertilizer production in 2011 is described.Production of sulphuric acid increased by 8.0% to 79 738 kt（as H2SO4）,with 38 441 kt from sulphur,21 297 kt from metallurgical off-gas,19 691 kt from pyrite and 309 kt from others.Production of phosphate fertilizer increased by 3.7% to 16 412 kt（as P2O5）,with 86.1% from high-analysis phosphate fertilizers,production of high-analysis phosphate fertilizers increased by 8.5% to 14 126 kt.Imported sulphur decreased by 9.3% to 9 523 kt,imported sulphuric acid decreased by 31.1% to 1 110 kt,72.2% of which was from Korea and 27.0% from Japan.It is predicted that China＇ s sulphuric acid and phosphate fertilizer production will maintain weak growth and the overall situation is more severe.
