| titleOfInvention | Integrated process for the commercial and industrial utilization of calcium sulfate from phosphoric acid production |
| abstract | A process is described for the production of sulfuric acid and cement clinker using calcium sulfate, which is formed and separated off as a solid by-product in a phosphoric acid production during the reaction of raw phosphate with sulfuric acid to form phosphoric acid, the process comprising the following steps: Calcium sulfate separated from phosphoric acid is treated with an acid in order to obtain a suspension with purified calcium sulfate, b) the purified calcium sulfate is separated as a solid from the liquid phase of the suspension obtained, whereby the liquid phase obtained can be introduced into the reaction unit of phosphoric acid production as a starting material , c) the separated purified calcium sulphate is mixed with additives and reducing agents in order to obtain a raw meal mixture for cement clinker production, d) the raw meal mixture is burned in order to obtain the cement clinker, with sulfur dioxide as exhaust gas is formed, and e) the sulfur dioxide formed is fed as raw material to a sulfuric acid production in order to produce the sulfuric acid, the sulfuric acid produced being used as a feedstock in the phosphoric acid production. In particular, the process is an integrated process. The integrative approach as an overall concept from phosphogypsum to cement clinker and sulfur dioxide takes into account the requirements in an existing phosphoric acid and sulfuric acid complex. |
