根据近几年我国进口硫磺量的迅速增长,2005年进口量达830万t,占全球硫磺产量的1/5,导致国际硫磺价格猛涨,1997年硫磺到岸价在35~45美元/t,2005年已达94.4美元/t以上,分析国际硫磺价格猛涨对我国磷复肥发展的巨大影响,而我国2006~2007年还将增加硫磺制酸能力540万t。为此,提出几点应对策略,新建硫酸装置应采取一炉两用的原料路线,并提出必须大力挖掘国内硫资源。 According to the rapid growth of China’s imports of sulfur in recent years, the import volume in 2005 reached 8.3 million tons, accounting for 1/5 of the world’s sulfur production, causing the price of sulfur in the world to soar. In 1997, the CIF value of sulfur was between 35 and 45 USD / t And reached over 94.4 USD / t in 2005. It is analyzed that the soaring international price of sulfur has a great impact on the development of phosphate compound fertilizer in our country. In 2006-2007, our country will increase sulfur acid production capacity by 5.4 million t. To this end, put forward a few countermeasures, the new sulfuric acid plant should be a dual-use raw material line, and proposed that we must vigorously tap the domestic sulfur resources.
