Description

磷酸-硫酸-水泥耦合的集成专利技术,采用中空转窑直接进行磷石膏还原化学分解;磷石膏采用非热力学耦合脱水,硫酸采用耦合工艺 Users applying this LCA data should include all major raw materials and all essential energy required for the production of 1 ton of sulfuric acid. The data excludes the production processes of raw materials and very minor energy flows (less than 1%). Systematic exclusions include infrastructure, services, or auxiliary facilities. It is crucial to consider these exclusions when using this data for environmental impact assessments and ensure that any comparative assessments account for similar boundaries and exclusions.
