摘要: 介绍了全球饲料磷酸盐生产技术现状,包括主要产品区域分布、生产量、生产商。着重介绍了饲料磷酸盐生产技术中的脱氟工艺技术(包括湿法磷酸的浓缩汽提脱氟工艺和沉淀脱氟工艺,湿法磷酸稀酸沉淀脱氟工艺)以及生产磷酸二氢钙(MCP)、磷酸一二钙(MDCP)、磷酸氢钙(DCP)、脱氟磷酸钙(DFP/TCP)等各类饲料磷酸盐产品的生产工艺技术。分析了可持续的饲料磷酸盐生产技术发展趋势。

关键词: 饲料磷酸盐, 湿法磷酸, 脱氟

Abstract: The globe current status of production technology of feed grade phosphate,including distribution production ca- pacity,and major producers,were introduced.The defluorination technologies(including concentration stripping defluorina- tion and precipitation defluorination technology of phosphoric acid by wet process and diluted acid precipitation defluorina- tion technology of phosphoric acid by wet process) in the production technology of feed grade phosphate were introduced em- phatically.The production technologies of various feed grade phosphates,such as monocalcium phosphate(MCP),mono-dicalcium phosphate(MDCP),dicalcium phosphate(DCP),and deflurized tricalcium phosphate(DFP/TCP),were also described in detail.The sustainable development trend of feed-grade phosphate production technology was analyzed at last.

Key words: feed-grade phosphate, phosphoric acid by wet process, defluorination
