Method for Producing Cement |
| 摘要 |
A method for producing calcium sulfoaluminate cement comprises the steps of providing thermal energy by combustion of sulphur and/or a sulphur-containing compound, reacting sulphur oxides produced by combustion of the sulphur and/or sulphur-containing compound with a mixture of calcium oxide and/or carbonate, and alumina and/or its hydrates to form a sulphur-containing mixture, heating the sulphur-containing mixture using the thermal energy to produce a clinker, and reacting remaining sulphur oxides produced by combustion of the sulphur and/or sulphur-containing compound with lime. The sulphur and/or sulphur-containing compound preferably comprises elemental sulphur, sour crude, sour gas or calcium sulfate. |
