| Use advice for data set | 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. |
| Technical purpose of product or process | The integrated patent technology for phosphoric acid-sulfuric acid-cement coupling utilizes a hollow rotary kiln for the direct chemical decomposition of phosphogypsum. This process allows for the co-production of sulfuric acid and cement clinker, leveraging non-thermodynamic coupling dehydration of phosphogypsum and the use of coupled processes for sulfuric acid. The resultant sulfuric acid is ideally suited for large-scale synthesis in the chemical industry, while the cement clinker is used for the construction industry as a primary component in cement production. |
