摘要
目前国内冶炼烟气制取的浓硫酸品质普遍不高,主要表现为浓硫酸杂质含量多、色泽差。以国内某硫酸生产企业200kt/a浓硫酸脱色提质改造项目为例,介绍了硫酸脱色提质的原理、工艺流程、各种关键设备的结构、材料选择等,重点详细阐述了宣达XDSS合金设备在浓硫酸脱色提质装置中的实际应用,为同行企业在类似装置中设备选材提供参考。
At present,the quality of concentrated sulphuric acid made by flue gas smelting is generally not good in domestic.Taking a 200kt/a concentrated sulphuric acid decolorization and upgrading project as an example in domestic,introduced the principle,process procedure,structure of various key equipment,material selection,etc.of sulphuric acid decolorization and quality improvement.Focus on the details of the practical application of XUANDA XDSS alloy equipment in concentrated sulphuric acid decolorization and quality improvement,providing reference for equipment material selection in similar unit for peer companies.
