摘要
利用老卤和电石渣反应合成氢氧化镁,再经煅烧形成氧化镁,达到将盐湖化工生产废弃物循环利用、减少盐湖废弃物直接排放的目的.根据试验室规模工艺研究结果,完成了年产500 t氧化镁装置设计及中试.
Abstract
Bittern is taken to react with carbide slag to synthesize magnesium hydroxide that is calcined to form magnesium oxide,aiming to achieve the purpose of recycling the chemical production wastes in Salt Lake and reducing the direct discharge of Salt Lake wastes.According to the results of laboratory-scale process research,the design and pilot test of a magnesium oxide plant with an annual production capacity of 500 tons are completed.
