“十一五”我国硫酸工业回顾及“十二五”展望（二）——硫磺回收与硫磺制酸

＂十一五＂期间我国硫磺回收和硫磺制酸发展较快。2010年我国硫磺回收产能在4 000～5 000 kt/a,产量为2870 kt,2006—2010年国内硫磺产能、产量年均增长率分别为22.7%,23.4%;2010年硫磺制酸产能为38 000 kt/a,产量为32980 kt,2006一2010年硫磺制酸产能、产量年均增长率分别为10.0%,10.8%。＂十一五＂期间通过技术引进和再创新,我国硫磺回收和硫磺制酸技术装备水平大有提高,在装置大型化、节能与热能回收利用、污染物减排等方面做了大量工作,有效推进了硫酸工业的节能减排和循环经济发展。预测到＂十二五＂末期我国硫磺产量将达到5 000 kt/a左右,硫磺制酸产能将达到47 000～50000 kt/a,产量约40000 kt/a,届时进口硫磺量将维持在10000 kt/a左右的水平。对今后加快淘汰落后产能、减少SO_2排放、推广节能和低温位热能回收技术、保障硫磺稳定供应等提出一些建议。

Review of Eleventh Five-Year Plan and outlook of Twelfth Five-Year Plan in China's sulphuric acid industry(Part two)-Sulphur recovery and sulphur-burning sulphuric acid production

China's sulphur recovery and sulphur-burning sulphuric acid production showed rapid development during the Eleventh Five-Year Plan period.Sulphur recovery capacity and production reached 4 000-5 000 kt/a and 2 870 kt in 2010,respectively,at average annual growth rate of 22.7%and 23.4%in 2006-2010.Sulphurburning sulphuric acid capacity and production reached 38 000 kt/a and 32 980 kt in 2010,respectively,at average annual growth rate of 10.0%and 10.8%in 2006-2010.Technology and equipment of sulphur recovery ...
