Analysis of China's sulphuric acid production situation in 2005

介绍2005年全国磷肥、硫酸生产情况。磷肥产量(以P_2O_5计)11 250 kt,其中高浓度磷肥6 780 kt(磷酸二铵2 330 kt、磷酸一铵2 550 kt、NPK复合肥1 350 kt),低浓度普钙、钙镁磷肥4 470 kt。硫酸产量(以H_2SO_5计) 46 250 kt,其中硫磺制酸19740 kt、冶炼烟气制酸产量9 810 kt、硫铁矿制酸产量16 120 kt、其它制酸产量580 kt。 2005年全国硫酸表观消费量48 180 kt,化肥用酸量占69．3％,非化肥用酸占表观消费量30．7％。根据磷肥的生产情况,预计2006年硫酸产量可超过53 000 kt。

China＇s phosphate fertilizer and sulphuric acid production in 2005 is introduced. Production of phosphate fertilizer reached 11 250 kt（ as P2O5 ） ,including 6 780 kt high-analysis phosphate fertilizer ,which was composed of 2 330 kt DAP, 2 550 kt MAP and 1 350 kt NPK compound fertilizer, and 4 470 kt SSP and FMP. Sulphuric acid production reached 46 250 kt（ as H2SO4 ） , 19 740 kt from sulphur,9 810 kt from smelter offgas, 16 120 kt from pyrite and 590 kt from others. Apparent consumption of sulphuric acid in 2005 reached 48 180 kt,69.3% for fertilizer purpose and 30. 7% for other industries. According to the production situation of phosphate fertilizer,it is forecasted that China＇s sulphuric acid production in 2006 will attain 53 000 kt.
