HRS技术在冶炼烟气制酸装置中的应用与实施

Application and implementation of HRS technology in sulphuric acid plants based on smelter off-gas

介绍了孟莫克HRS技术在2套800 kt/a铜冶炼烟气制酸装置中的应用与实施。简要介绍了制酸装置概况,详述了HRS系统的工艺流程、主要设备、仪表及自动化,以及项目的实施,包括采购与供货、制作与施工、试车与开车等。每套制酸装置生产低压饱和蒸汽52.1 t/h,产汽率达到0.493 t/t,收到良好的经济和环境效益。

Application and implementation of MECS HRS technology in two 800 kt/a sulphuric acid plants based on smelter off-gas are described. The summary of sulphuric acid plant is given briefly and HRS system is detailed with emphasis on process flow, main equipment, instrument and automation, as well as project implementation including purchase and supply, fabrication and construction, and commissioning and startup. The production of low-pressure steam for each plant reached 52. 1 t/h with a steam generating rate of 0. 493 t/t, resulting in good economic and environmental benefits.
