Calcium oxide (CaO), commonly known as burnt lime, lime or quicklime, is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid. As a commercial product lime often also contains magnesium oxide, silicon oxide and smaller amounts of aluminium oxide and iron oxide.
Calcium oxide is a key ingredient for the process of making cement. As a cheap and widely available alkali. About 50% of the total quicklime production is converted to calcium hydroxide before use. Both quick- and hydrated lime are used in the treatment of drinking water.
Fine and coars stone are taken as required from the kiln stone store for the burning process and burnt in the shaft kiln to form lump lime. The calcium carbonate (CaCO 3) is converted into calcium oxide (CaO).

Applications of Quicklime. Quicklime is used in a wide variety of applications, including the manufacture of iron and steel, the manufacture of paper and pulp, the treatment of water and flue gases and the mining industry. In the basic oxygen steelmaking (BOS) process, quicklime is known to have very crucial applications.
Properties of Calcium Oxide. Quick lime is an amorphous white solid with a high melting point of 2600 °. It is a very stable compound and withstands high temperatures. In the presence of water, it forms slaked lime. This process is called the slaking of lime. CaO+H2O → Ca (OH)2.

production process, emission controls, and inputs into this process. In addition, characterizing the supply side of the industry involves describing various types of lime products, by-products of the production process, and input substitution possibilities. Finally, this section explains costs of production and economies of scale.
1. Introduction. Quicklime (CaO) is an inexpensive, effective and widely used industrial chemical. In 2019, global production of quicklime was around 430,000,000 metric tonnes .Quicklime is produced by the thermal processing of naturally occurring limestone in industrial kilns.
The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.

Jun 11, 2018· Calcium oxide (KAL-see-um OK-side) is an odorless crystalline or powdery solid that, in a pure form, is white to off-gray. It often appears with a yellowish or brownish tint to the presence of impurities, especially iron. Calcium oxide reacts with water to form calcium hydroxide (Ca (OH) 2) with the evolution of significant amounts of heat.
Lime is produced in a thermal process known as calcination according to the reaction. CaCO3 + Heat = CaO + CO2. Heat causes the calcium carbonate to lose a molecule of carbon dioxide. The end product is calcium Oxide, better known as unslaked lime or quicklime. At Ndola Lime this process is achieved in oil-fired rotary and vertical kilns.
Calcium oxide, in its direct form, reacts slowly with carbon dioxide. Therefore, to accelerate the process, it is mixed with water to form carbon hydroxide, also known as slaked lime. The chemical equation is as follows: CaO + H 2 O Ca(OH) 2. This calcium hydroxide quickly reacts with …
quicklime desiccant production process flow. Sep 14, 2016· The pulp and paper industry integrates different manufacturing and chemical processes to prepare a variety of products essential to modern society. To complete these processes, the industry requires many different compounds for a variety of tasks. One of these is lime.
11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains

Only if the lime-burning process is kept at an optimum temperature range between +900…1100°C / +1652…2012°F can CO 2 be liberated from the limestone to obtain the desired quicklime product. It is therefore very important for the customer to control the burning process and to …
A lime manufacturer operates a production site for quicklime in Portugal. The plant comprises a state-of-the-art calcination unit with a natural gas fired lime kiln. In this furnace calcium carbonate (CaCO 3) extracted from nearby quarries is exposed to high temperature. This lime-burning process causes carbon dioxide (CO 2) to detach from the CaCO

A process of a carbon dioxide free process for the production of calcium oxide (STEP cement) is presented here in which molten calcium carbonates are electrolyzed to oxygen and reduced carbon, and producing calcium oxide. In the direct electrolysis process, calcium carbonate is preferably dissolved with other molten carbonates, or may be used pure.
Lime Production Process involves four steps: 1) Mining or Quarrying. Limestone material is extracted carefully to maintain its purity in underground mines and quarries all over the world. 2) Stone Preparation. In this step, the limestone is crushed and screened to further wash and remove impurities. 3) Lime Calcining (Conversion of limestone ...
