摘　　要：根据工程实践介绍了贵金属过滤器在硝酸装置中的应用。通过现场工程案例指出贵金属过滤器对铂、钯细小颗粒实现了拦截,但不影响工艺气的正常流动,压差在允许范围内,实现了贵金属有效回收利用的目的。This paper introduces the application of the noble metal filter in the nitric acid plant according to the engineering practice.Through field engineering cases,it is pointed out that the precious metal filter can intercept platinum and palladium fine particles,but it does not affect the normal flow of the process gas,and the pressure difference is within the permitted range,which realizes the purpose of effective recycling of precious metals.
