Heating Calcium Carbonate Equipment

Heating Calcium Carbonate Equipment

Thermal decomposition of calcium carbonate Experiment ...

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate

Predicting Calcium Carbonate Scaling ... - Process Heating

Jan 11, 2019  Predicting calcium carbonate scale in water systems has been done for more than 20 years — often with questionable or even inaccurate results rather than actual field observations. Perhaps the oldest method is the marble test[1], a crude, qualitative test used primarily for potable water rather than cooling water. The marble test method led to the development of a more quantitative method by ...
