Abstract:

China has been ranked the first in its sulfuric acid production since 2004，and the production in 2006 reached 50.43 Mt. A new raw material pattern mainly consisting of sulfur，pyrite and metallurgical off-gas is established. Since reform and opening-up，a high level of intensive production of China’s sulfuric acid industry has been achieved，with the largest sulfuric acid plant being 400 kt/a with pyrite，1000 kt/a with sulphur and 600 kt/a with metallurgical off-gas. China’s sulfuric acid industry will step towards larger plant size，higher level of intensive production and higher level of technologyl and equipment，as well as strengthening energy saving and environmental protection，in order to realize recycling economy and sustainable development.

摘要： 介绍了2004年至今中国硫酸产量位居世界首位，2006年中国硫酸产量达50.43 Mt，逐渐形成了以硫磺、硫铁矿和冶炼烟气为主的原料结构。改革开放以来，中国硫酸行业的产业集约化程度大幅提高，单系列硫酸装置的最大规模分别为硫铁矿制酸400 kt/a、硫磺制酸1000 kt/a、冶炼烟气制酸600 kt/a。还指出今后中国硫酸工业的发展趋势是：装置进一步大型化，产业集约化程度继续提高，全方位提升技术装备水平，加大节能减排力度，提高废热回收利用率，走循环经济的发展道路，实现可持续发展。
