用硬石膏生产硫酸和高贝利特水泥工艺探析(续前)

Process Analysis for Production of Sulfuric Acid and High Belite Cement Using Anhydrite (finished)

基于硬石膏是一种理想的硫资源,以湖南湘福新型建材公司硬石膏生产硫酸联产高贝利特水泥项目为例,介绍了用硬石膏同时生产硫酸和水泥的原理、工艺流程和设备,阐述了生产条件和工艺控制要求,对装置在生产工艺过程存在的主要问题进行了探讨和总结,并作技术经济分析论证了该项目具有重大的经济意义。

Based on the fact that anhydrite is an ideal sulfur resource,and by taking the example of the project for production of sulfuric acid with coproduct of high belite cement using anhydrite by Hu'nan Xiangfu New Building Materials Co.,Ltd.,the principle,process follow and equipment for the production of co-production of sulfuric acid and cement using anhydrite are introduced,and the production conditions and process control requirements are described. main issues in the production process of the plant are analyzed and summarized,and it is concluded that the project offers major economic significance by technical economic analysis.
