世界最大冶炼烟气制酸厂的设计

Design of the World's Largest Metallurgical Acid Plant

最近,鲁奇公司(Lurgi)为澳大利亚芒特艾萨西部矿业化肥公司建设的世界最大冶炼烟气制酸厂投产,该厂最大生产能力4200t/d,采用LSTK技术,主要处理铜冶炼及转炉烟气,并补充燃烧部分硫磺以满足化肥厂对硫酸的需求。本文主要介绍了工艺及机械设计及工程的大量详细情况,并强调了设计安装的主要特点,还讨论了设计依据及由此决定的部分主体设备的特性。

Lurgi has recently commissioned the world's largest metallurgical sulfuric acid plant with a peak capacity of 4,200mtpd(4,630 stpd), built on a LSTK basis for Western Mining Fertilizer in Mt. Isa,Australia.The plant is based on copper smelter and converter off gas with complementary sulfur burning to match the acid demand of the associated fertilizer production.The main design features of the installation are highlighted.The paper focuses on process and mechanical design issues and it presents a number of interesting details of the project. Those criteria and some resulting features of the main equipment are discussed.
