PURIFYING HIGHLY IMPURE CALCIUM HYDROXIDE AND PRODUCING HIGH-VALUE PRECIPITATED CALCIUM CARBONATE AND OTHER CALCIUM PRODUCTS |
| 摘要 |
A solution process for the purification of calcium hydroxide, particularly from hydrated carbide lime, which is subsequently used as a feed stock for a high-value calcium product, preferably calcium carbonate. Precipitated calcium carbonate is formed by reaction of the purified calcium hydroxide solution with carbon dioxide in a plug-flow reaction system.
