Production and operation of China's sulphuric acid industry in 2017 and outlook for 2018

LI Chong;LIAO Kangcheng;China Sulphuric Acid Industry Association;  
China's sulphuric acid production in 2017 is described.China's total output of sulphuric acid is 96 130 kt in 2017,increase by 0. 5% year-on-year.The yield of sulphur-burning sulphuric acid was 43 610 kt,accounting for 45. 4% of total production,increase by 1. 7% year-on-year.The production of acid from smelter flue gas was 33 640 kt,account for 35%,increase by 1. 5%.Production of sulphuric acid from pyrite was 17 920 kt,account for 18. 6% and down 0. 5%. 960 kt from other raw materials,accounting for1. 0%. In 2017,China's cumulative import of sulphuric acid was 1 213 kt and down 15. 4% year-on-year,the cumulative export of sulphuric acid was 693 kt and increase by 990. 2% year-on-year.China's sulphuric acid watch consumption of 96 650 kt and down 0. 36%year-on-year.China's sulphur production was about 5 940 kt,increase by 8% year-on-year,and imports of sulphur 11 236 kt,down6. 1% year-on-year.The output of pyrite in China was 14 588 kt,increase by 3. 3% year-on-year.In 2018,the new sulphuric acid production capacity is expected to be 11. 2 Mt/a,of which 8 Mt/a is from non-ferrous smelter flue gas making acid.It is estimated that by the end of 2018,the total capacity of China's sulphuric acid will reach 140 Mt/a,and the utilization rate of sulphuric acid will be reduced to below 70%.
