Operation summary and design review of Daye sulphuric acid plant based on converter off-gas 大冶转炉烟气制酸装置运行总结及设计评述
Introduction of Daye sulphuric acid project based on converter off-gas 大冶转炉烟气制酸工程介绍
The Port Kembla Copper ( PKC) copper smelting facilities were commissioned during 2000. Numerous difficulties were encountered during the commissioning such as multiple reactor tuyere line failures, absorbing acid tower refractory collapse, and Noranda Reactor and Mitsubishi Converter process control problems. 改建的肯布拉港铜冶炼厂2000年投入运行。试车时遇到很多问题,例如诺兰达炉风口区多次烧穿、吸收塔耐火材料崩落以及诺兰达炉和三菱吹炼炉工艺控制出现问题。
The acid mist content at the exit of sulphur combustion furnace ( or at the entrance of converter) in the sulphuric acid process using sulphur as raw material and the influent factors are calculated and discussed in the article. 对硫磺制酸系统焚硫炉出口(或转化器进口)气体中的酸雾含量及其影响因素进行了计算与讨论。
Some problems are discussed such as cleaning process for pyrite-based sulphuric acid production, utilization and development of waste heat recovery system, research of pyrite roasting and design optimum of converter. 探讨了硫铁矿制酸稀酸净化、热能回收系统的利用和开发、硫铁矿焙烧研究及转化器的优化设计等问题。
