In 2007, China’s sulphuric acid production reached 33. 712 million t, compared with the previous year yield 3. 2 million t, up 10. 5 percent, from a long position in second place, overtaking the United States of 30. 5 million to 31 million t. As sulphur imports have been running high prices, some of sulfur acid plants back pyrite acid, pyrite acid changed the downward trend of the past, the output reached 13. 034 million t, than the 2002 growth of 8. 1 percent, accounting for the total output The 38. 7 percent;
sulfur acid production was 12. 609 million t, accounting for 37. 4 percent of total output; smelting acid gas output was 7. 521 million t, the total output accounted for 22. 3 percent of phosphogypsum and other acid production was 547,000 t. ?2003 China’s apparent consumption of sulphuric acid 35652000 t. Among them, phosphate and compound fertilizer use accounted for 67. 6% acid, an increase of 18%; other fertilizer consumption of 4. 1 percent; non-chemical fertilizers used acid 28. 3 percent, an increase of 8. 7 percent. Although domestic production increased rapidly, but still can not fully meet the demand. 2003 sulphur imports 4. 99 million t, an increase of 22 percent, and imports from the sulfuric acid 1939000 t, and basically the same as the previous year. ?
2004 sulphuric acid production and the market appear not a good situation for many years, of which there are two reasons, first, from the beginning of the end of 2003, the Central clutching three agricultural issues and put forward a series of chemical fertilizer enterprises favorable policies to promote the special phosphatic compound fertilizer Is the high concentration of phosphate and compound fertilizer production, phosphate and compound fertilizer per month to more than 20 percent year-on-year growth in the second is the rapid growth of the national economy, increasing the demand for sulphuric acid, in 2004, an increase of the monthly output of sulphuric acid in 18% Above, the sulphuric acid market in one of the short supply situation, prices all the way up. 2004 National sulfate production 39. 946 million tons, an increase of 18. 5% (detailed in the table below). Yunnan is the largest output.
