摘　　要：介绍了俄罗斯某铜厂800 kt/a铜冶炼烟气制酸装置的EPS工程实践。详述了该项目的冶炼烟气特点、制酸工艺方案选择及主要设备选型。该装置采用"3+1"二转二吸、ⅢⅠ-ⅣⅡ换热流程,核心设备为内置换热器的转化器,一吸塔和二吸塔共用1台吸收酸循环槽。投入运行后SO2转化率大于或等于99.90%,SO_3吸收率大于99.99%,尾气排放φ(SO_2)小于或等于0.013%。The engineering practice of EPS in an 800 kt/a copper smelter flue gas sulphuric acid system in Russia was described in detail, including the characteristics of copper smelter flue gas, the choices of the sulphuric acid process schemes and the main equipment selection. The process included ＂3＋ 1＂ double conversion and double absorption, Ⅲ Ⅰ-ⅣⅡheat exchange flow scheme. The main equipment was a built-in heat exchanger converter. The primary and the secondary absorption towers shared one aid circula- tion tank. The operation showed that SO2 conversion reached to 99. 90% or more, SO3 absorption rate greater than 99.99%, and SO2 concentration in tail gas less than to equal to 0. 013%.
