硫磺是化学工业的重要原料,广泛用于农业、火药、酿酒、制糖等各种领域。在国外,硫磺主要用于硫酸的生产,占硫酸总用量的80％以上,其它作为专用硫磺使用。而我国硫磺的消费情况则与之恰恰相反,用于生产硫酸的不到30％,而70％以上作为专用硫磺使用。 我国天然硫矿虽有十多个点,但其储量很小,至今还未开采。由于我国石油中含硫量较低,所以石油回收硫磺也较少。近几年随着原油加工量和进口油加工量的增长,石油回收硫磺也在逐年增长,其硫磺 Sulfur is an important raw material for the chemical industry and is widely used in various fields such as agriculture, gunpowder, brewing, and sugar production. In foreign countries, sulfur is mainly used for the production of sulfuric acid, accounting for more than 80% of the total amount of sulfuric acid. Others are used as special sulfur. The consumption of sulfur in China, on the other hand, is less than 30% of the production of sulfuric acid, and more than 70% of sulfur is used as special sulfur. Although there are more than 10 natural sulphur mines in China, their reserves are very small and have not yet been mined. Due to the low sulphur content in China’s petroleum, less sulphur is recovered from petroleum. In recent years, with the increase in the volume of processed crude oil and the processing volume of imported oil, the recovery of sulfur from petroleum has also increased year by year.
