硫酸与磷酸是磷肥与磷化工行业的基础原料,目前磷酸与硫酸各种生产工艺都在进步,其生产原料涉及硫、磷资源。本栏目征集硫酸与磷酸生产新技术、新工艺、生产经验、技术改造资源利用等方面的文章,具体如下:1)磷酸(湿法磷酸、热法磷酸、窑法磷酸、非硫酸法磷酸等)与硫酸(矿制酸、硫黄制酸、烟气制酸等)各种工艺的创新技术及技术进展。2)湿法磷酸新产品(工业级磷酸、食品级磷酸、固体磷酸、高纯磷酸等)的开发及其工艺技术。
Sulfuric acid and phosphoric acid are the basic raw materials for phosphate fertilizer and phosphorus chemical industry. At present, various production processes of phosphoric acid and sulfuric acid are making progress. The raw materials for their production involve sulfur and phosphorus resources. This column solicits articles on new technology, new technology, production experience and resource utilization of sulfuric acid and phosphoric acid production as follows: 1) Phosphoric acid (wet process phosphoric acid, pyrogenic phosphoric acid, kiln phosphoric acid, non-sulfuric acid phosphoric acid, etc.) And sulfuric acid (mineral acid, sulfuric acid, flue gas acid, etc.) a variety of innovative technology and technological progress. 2) The development of wet-process phosphoric acid new products (industrial-grade phosphoric acid, food grade phosphoric acid, solid phosphoric acid, high-purity phosphoric acid, etc.) and its process technology.
