In 2007, the production of sulfuric acid in China reached 33. 712 million tonnes, compared to the performance of the previous year 3. 2 million tonnes, 10. 5 percent, from a long position in second place by beating the United States, 30. 5 to 31 million tons As imports acid pyrite sulfur were running high prices, some of the sulfuric acid plants back, acid pyrite changed the downward trend of the past, production has reached 13. 034 million t, that growth in 2002, 8. 1 per cent, which represents the total output of 38 years. 7 percent;
acid production of sulfur 12. 609 million tonnes, with 37. 4 percent of total production, smelter production of sour gas was 7. T $ 521 million, total production amounted to 22. 3 percent of phosphogypsum and other acid producing 547,000 tons ? 2003, apparent consumption of China 35,652,000 tons of sulfuric acid, among them the use of phosphate and compound fertilizers accounted for 67. 6% acid, an increase of 18%, the consumption of fertilizers other than 4. 1 per cent of non-chemical fertilizers used 28 acids. 3 percent, an increase of 8. 7 percent. While domestic production has increased rapidly, but still can not meet demand. 2003, imports of sulfur 4. 99 million tonnes, an increase of 22 percent, and imports of 1,939,000 tons of sulfuric acid, and essentially the same as the previous year. ?
2004, production of sulfuric acid and the market seems to be a good situation for many years, of which there are two reasons, first, from the beginning of the end of 2003, seizing the central three agricultural issues and introduced a number of fertilizer companies favorable policies to promote special fertilizer phosphate compound is the concentration of the production of phosphate fertilizers and compound fertilizers and phosphate compounds per month to more than 20 percent growth every year in the second is the rapid national economic growth, increasing demand for sulfuric acid in 2004, an increase of the monthly production of sulfuric acid 18% above market for sulfuric acid in the shortage, all prices upwards. 2004 national production of sulphate 39. 946 million tonnes, an increase of 18. 5% (as shown in the table below). Yunnan is a major break.
