云南省硫酸磷复肥行业“十二五”回顾及“十三五”展望

Twelfth five-year plans review and thirteenth five-year plans outlook for Yunnan province sulphuric acid and phosphate compound fertilizer industries

截至2014年底,云南省硫酸产能为16 450 kt/a,其中硫磺制酸产能10 330 kt/a、占62.8%;烟气制酸产能3 700 kt/a、占22.5%;硫铁矿制酸产能2 420 kt/a、占14.7%。2014年硫酸产能发挥率86.0%。在磷肥总量中,高浓度磷复肥产量在过去的4年中稳定在84%以上,2014年达到89.2%。磷酸二铵比例有所降低,但仍是云南省磷复肥工业的主要支柱品种。重点介绍了"十二五"期间云南省硫酸磷复肥装置的技术创新和转型升级亮点及存在的问题。展望"十三五",云南省硫酸及磷复肥将进入新的产业调整期,以质量和效益为中心"调结构、转方向"。

By 2014,the production capacity of sulphuric acid reached 16 450 kt / a in Yunnan province,of which production of burning sulphur acid was 10 330 kt / a,accounting for 62. 8%; production of smelting acid was 3 700 kt / a,accounting for 22. 5%;production of acid from pyrite mine was 2 420 kt / a,accounting for 14. 7%. The capacity utilization was 86. 0%. For total phosphate fertilizer,the production of high concentrated phosphorous compound fertilizer stabilized at more than 84% for the last four years,the production reached 89. 2% in 2014. The proportion of diammonium phosphate decreased but was still the main product for phosphorous compound fertilizer in Yunnan province. The review highlighted the technology innovation,improvement and upgrading for phosphorous compound fertilizer unit operation and existing problems during the twelfth five-year plans. To outlook the thirteenth five-year plans,it is obvious that the sulphuric acid and phosphate fertilizer industries will enter into a new period for industrial restructuring and redirecting,centered on quality and efficiency.
