Apparatus and process for purifying highly impure calcium hydroxide and for 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.
