Quicklime is an alkaline and caustic chemical compound made by heating limestone at very high temperatures to force off carbon dioxide, acting as a raw material in producing calcium hydroxide and hydrated lime for water treatment applications.

This material is a caustic alkali that can burn skin and eyes. Furthermore, its fumes may irritate nasal passages and throat passages leading to labored breathing and coughing episodes.

Quicklime is an invaluable component in numerous industries such as construction, environmental remediation, agriculture, steelmaking and pulp and paper production. Produced from limestone of different textures through calcination processes, quicklime is indispensable in modern life.

Calcium Carbonate

Calcium carbonate can be found worldwide in limestone deposits. When burned at 900 degrees Celsius, limestone becomes calcium oxide (CaO) commonly referred to as quicklime. This chemical reaction has been known since prehistoric times and its name can be found in many languages – meaning “burnt lime”.

Lime cycle production also involves producing slaked lime and hydrated lime products, both of which have many applications ranging from construction materials like plaster and concrete, agricultural control of soil pH levels, water treatment processes such as flue gas desulfurization as well as steel manufacturing and pulp and paper production.

Quicklime can be highly reactive; therefore full protective gear must always be worn when handling it.

As it contains corrosive substances that may burn the skin or eyes, as well as respiratory-irritant dust particles, personal safety is of utmost importance when working with it; wearing a face mask even in areas with adequate ventilation is recommended for safety.

Quicklime mixed with water produces calcium hydroxide and lime water, both caustic soda solutions with numerous uses including cleaning and deodorizing applications. Many household cleaning powders include qucklimes as an ingredient. It’s even an integral component in agricultural applications like liming corn.

Exothermic Reaction

Quicklime reacts with water in an exothermic reaction that produces large amounts of energy, making it an exothermic reaction and highly corrosive. Therefore it is advised that when working with quicklime you use all necessary personal protective equipment (goggles, head hood, cotton work suit and rubber or polyurethane gloves).

Inhalation of its powder can cause respiratory irritation; any contact between inhaled powder and your eyes must be rinsed off with water and medical advice sought immediately if respiratory irritation arises.

Quicklime is widely utilized as an industrial raw material due to its chemical and physical properties. A white or gray powder with granular texture and high heat capacity, quicklime reacts with water to form calcium hydroxide or “slaked lime”.

Heat Capacity

Quick lime powder boasts an exceptional heat capacity, which enables it to generate vast quantities of steam and energy during its slaking process. This energy can be harnessed and made use of. You can visit this site to learn more about this process.

Quick lime’s thermal properties make it an effective way to regulate sludge digestion processes and other industrial operations and help destroy pathogens in the sludge by means of exothermic reactions related to its hydration and decomposition.

Limestone (calcium carbonate) can be heated until it glows to drive off carbon dioxide and form an unslacked or burned powder called quicklime. After heating, this dry powder can then be slaked by adding water (H2O), producing Ca(OH)2, which gradually returns back into limestone as its carbon dioxide reacts with airborne carbon dioxide molecules.

Before entering the combustion zone, limestone particles are in a preheating zone using carrier gas to ensure only high-purity CO2 is emitted by fuel combustion – saving fuel, reducing emissions and improving quality of the final lime product.

Calcium Carbonate

Storage

Quicklime has an extremely reactive nature, requiring it to be stored appropriately or risk being exposed to air or moisture which could contaminate it, as well as water seeping into its container of storage.

Use proper techniques for storing quicklime to save money and extend product lifespan.  Be sure to use approved storage containers for best results.

Quicklime can best be protected from moisture by placing it in an insulated and sealed tank equipped with temperature sensors that automatically adjust its operating temperatures according to ambient conditions.

Quicklime produces an intense glow when heated to high temperatures. This is commonly referred to as limelight and was often employed in theatrical performances before electric bulbs were invented.

Quicklime can also be utilized to exploit its exothermic properties through compressed lime cartridges, which are placed into shotholes to break apart rock formations.

Not only is there an exothermic reaction taking place, but its hydrate also absorbs some of the surrounding heat from rock. There are multiple grades of quicklime available and consulting with chemical suppliers or manufacturers is one way of understanding which grade would work best in an end application scenario.
