由于硫的需求减少以及苏联新建大型回收硫工厂的剧烈竞争,目前在世界市场采用弗雷舍(Frasch)溶浸硫方法显得很不景气。近期内,增加全世界弗雷舍溶浸硫法的产量可能是有限的。长远来看,提高需求量时应注意元素硫的副产资源和更好地发展新的弗 Due to the reduced demand for sulfur and the fierce competition from the new large-scale recovery sulfur plant in the Soviet Union, the current Frasch leaching of sulfur in the world market is in a downturn. In the near term, increasing the worldwide production of Fraser’s FTZ may be limited. In the long run, attention should be paid to the by-product resources of elemental sulfur and to better development of new fuels
