回顾2000~2006年云南硫酸、磷肥产量增长情况,提出云南硫酸磷肥工业的发展蓝图。2010年硫酸产能达1250万t/a,并要加快大中型硫磺制酸装置低温位热能回收利用。云南磷肥工业将以大中型高浓度磷复肥企业为主,以整合重组后的低浓度磷肥企业为辅。云南磷肥工业的发展将会主要依托云南云天化国际化工股份有限公司(简称“国际化工)”,到2010年,云南85%~90%高浓度磷复肥、50%的过磷酸钙将集中在“国际化工,”产能分别达290万t/a和36万t/a(折纯P2O5)。磷矿产量(折标)2010年预测达2 000万t/a,其中擦洗与浮选磷矿将占70%。
Recalling the growth of Yunnan sulfuric acid and phosphate fertilizer production from 2000 to 2006, put forward the blueprint for the development of Yunnan sulfuric acid phosphate fertilizer industry. 2010 sulfuric acid production capacity of 12.5 million t / a, and to speed up large and medium-sized sulfuric acid plant at low temperature heat recovery. Yunnan phosphate fertilizer industry will be large and medium-sized high-concentration phosphate compound fertilizer-based enterprises to integrate the restructuring of the low-concentration phosphate fertilizer supplement. Yunnan phosphate fertilizer industry will mainly rely on Yunnan Yuntianhua International Chemical Co., Ltd. (“International Chemical”), by 2010, Yunnan 85% to 90% of the high concentration of phosphate compound fertilizer, 50% of the superphosphate will be concentrated in “International Chemical,” production capacity of 2.9 million t / a and 360,000 t / a (pure P2O5). Phosphate rock production (index) 2010 forecast of 20 million t / a, of which scrubbing and flotation of phosphate rock will account for 70%.
