Calcium Hydroxide

Definition - What does Calcium Hydroxide mean?

Calcium Hydroxide is an inorganic compound which is generally known as slaked lime or milk of lime. Its chemical formula is Ca(OH)2 and it is formed when Calcium Oxide is combined with water, hence the name slaked lime. Being an alkaline solution, it is used to remove or neutralize carbonate ions, carbon dioxide and hydrogen sulfide from any solution. It has stabilizing properties and it is due to these variant properties that it is used in a myriad of industrial applications right from plastering walls to treating sewage.

Petropedia explains Calcium Hydroxide

Calcium Hydroxide or hydrated lime is used in many industries including the oil and gas industry. This solution is obtained when calcium oxide is combined with water. The chemical property of this solution has a neutralizing effect and it is used as an additive in the drilling fluids used in the petroleum refining industry. The reasons why calcium hydroxide is used in drilling fluids is because of its increased pH level that provides additional alkalinity. It also removes soluble carbonate ions and it is also used in the oil-base mud additives. This solution is relatively safe for use and does not cause any harm to the user or the industry.
