摘要
针对白银有色集团股份有限公司第三冶炼厂硫酸装置以烧结烟气为原料生产硫酸过程中,硫酸产品易发红的情况,结合生产工艺,利用分析检测手段,通过试验查明了原因。对氮氧化物存在对硫酸色度的影响进行了定性定量试验研究,对氮氧化物的存在对硫酸外观颜色影响的机理进行了分析。
s：In view of the fact that sintering flue gas is used as raw material to produce sulfuric acid at the acid plant of the No.3 smelter under Baiyin nonferrous group Co .Ltd., and based on the existing production process and available analysis and detection , the reason why sulfuric acid is prone to becoming red is found out through the experiment .Qualitative and quantitative experimental study is carried out to examine the impact of nitric oxide on colority of sulfuric acid , and the mechanism is analyized for the influence by nitric oxide to the appearence and color of the acid .
