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.
