利用热化学模型和工业数据,对以下工艺方法铜硫化矿熔炼过程中能源消耗进行计算:a)闪速熔炼+闪速吹炼;b)艾萨熔炼+PS转炉吹炼;c)三菱法连续铜熔炼和吹炼;d)诺兰达/特尼恩特连续熔池熔炼+PS转炉吹炼。对于这些方法,作业的范围包括渣中有价金属的回收,工艺过程中烟气的热回收,以及工艺过程中烟气和环保烟气中SO2的回收,在此项研究中采用了单元计算法,因此可以快速评估其他工艺流程,如“闪速熔炼+PS转炉吹炼”。尽管天然气是用于计算的重要燃料,但该模型也可很容易计算出替代燃料所产生的影响。
Using the thermochemical model and industrial data, the energy consumption of the copper sulphide ores in the following process is calculated: a) Flash smelting + flash blow; b) Isa smelting + PS converter blowing; c) Mitsubishi method for continuous Copper smelting and blowing; d) Nolander / Tenente continuous smelting + PS converter blowing. For these methods, the scope of operations includes the recovery of valuable metals in the slag, the heat recovery of flue gas in the process, and the recovery of SO2 in the flue gas and environmentally friendly flue gas during the process. In this study, the unit calculation method , So you can quickly evaluate other processes, such as “Flash smelting + PS converter blowing ”. Although natural gas is an important fuel for calculation, the model can easily calculate the effects of alternative fuels.
