“十一五”我国硫酸工业回顾及“十二五”展望(四)——其他原料制酸与硫酸消费

Review of Eleventh Five-Year Plan and outlook of Twelfth Five-Year Plan in China's sulphuric acid industry(Part four)-Other raw materials-based sulphuric acid production and sulphuric acid consumption

"十一五"期间我国其他原料制酸得到较快发展,截止到2010年我国有其他原料制酸装置40套,总产能约2400kt/a,产量仅约700kt。"十一五"期间通过技术引进和自主创新,我国其他原料制酸技术装备水平大有提高,在制酸原料多样化、装置大型化、节能减排和资源综合利用等方面成效显著,有效推进了硫酸工业的节能减排和循环经济发展。2010年我国硫酸表观消费量达到71705kt/a,"十一五"期间我国硫酸表观消费量年均增长率达到8.3%,其中磷肥用酸年均增长率为8.4%,工业用酸年均增长率为7.5%。预测到"十二五"末期我国硫酸总消费量将达到89000kt/a左右,其中约57000kt/a来自化肥用酸,约32000kt/a来自工业用酸。预计2015年我国硫酸总产能将超过100Mt/a,产量约88000kt;其中其他原料制酸产能将达到4500kt/a,产量约2000kt。对今后加快含硫废物制酸利用、推广节能减排技术、提升制酸技术装备水平、积极应对产业政策影响等提出一些建议。

China＇s other raw materials-based sulphuric acid production showed rapid development during the Eleventh Five-Year Plan period.The production capacity of 40 other raw materials-based sulphuric acid plants amounted to about 2 400 kt/a and production about 700 kt in 2010.Technology and equipment of other raw materials -based sulphuric acid production reached a new higher level through technical introduction and re-innovation, such as diversity of raw materials,installation of large-scale plants,saving energy and reducing emissions, and comprehensive utilization of resources,which effectively promoted the development of saving energy and recycling economy in China＇s sulphuric acid industry.China＇s apparent consumption of sulphuric acid reached 71 705 kt in 2010,at an average annual growth rate of 8.3%in 2006-2010.The average annual growth rate of apparent consumption for phosphate production and industrial products were 8.4%and 7.5%in 2006-2010,respectively. It is predicted that apparent consumption of sulphuric acid will reach about 89 000 kt/a by the end of the Twelfth Five-Year Plan,with 57 000 kt/a for fertilizer and 32 000 kt/a for industrial products.It is predicted that sulphuric acid capacity will reach over 100 Mt/a and production will reach about 88 000 kt/a in 2015,with other raw materials-based sulphuric acid capacity of 4 500 kt/a and production of about 2 000 kt.Some suggestions are presented,such as speeding up sulphuric acid production from sulphur-containing waste,promoting energy saving and emission reduction technology,raising technical and equipment level,and actively responding to industrial policy.
