摘要
介绍了国外浓硝酸大型化生产技术、设备及材质选用情况,分析了我国浓硝酸生产大型化过程中的生产方法、生产规模、科学试验和技术经济指标。要实现我国浓硝酸生产的大型化,在设备选材上要摆脱原有的高硅铸铁,选用既能耐浓硝酸又能耐稀硝酸腐蚀的材料。
The situations of foreign large scale concentrated nitric acid production technology, equipment and material selection are introduced, issues, such as production method, production scale, scientific experiment and technical and economic index, etc. of large scale production process of concentrated nitric acid in China are analyzed. To realize large scale production of concentrated nitric acid in China, in the respect of equipment material selection, the original be abandoned, and the materials which can resist the corrode of both dilute nitric acid should be selected and used. high silicon cast iron should concentrated nitric acid and
