The lime industry. The market is expected to grow at a CAGR of 5.87% in the forecast period of 2021-2026 to reach a volume of 543 MMT by 2026. The Asia Pacific is the leading region in terms of production, boosted by the rapidly growing construction industry
A lime flux consisting of quicklime or a blend of quicklime and dolomitic lime is added. The total flux amount varies from 50 to 120 pounds per ton of steel, and up to 50% may be dolomitic lime. Benefits of lime flux --The lime flux removes impurities and forms a slag that can be separated from the steel and poured from the furnace as a liquid.
As many steel plants produce the required quicklime in PFR lime kilns fired with different steel plant gases, this drop in efficiency is well known and has already been investigated 2. The effect of lower thermal efficiency on a PFR lime kiln only becomes noticeable when fuel gases have a net calorific value of less than 7 MJ/Nm 3 .
During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
Hydrated lime absorbs carbon dioxide from the atmosphere, forming calcium carbonate and water. It should, therefore, be stored in dry, draught-free conditions. Due to demand growth, Hydrated Lime is a good project for entrepreneurs to invest. Plant capacity 15000 MT/annum Plant machinery Rs. 264 Lakhs Working capital -

Lime in the Sugar Industry. Hydrated lime is essential to the production of sugar from both sugar cane and sugar beets. It is also used to purify sugar derived from other sources, such as maple or sorghum. Sugar cane and sugar beets are harvested and processed with water to form raw juice, which has low pH and contains dissolved impurities.
The chemical reaction to produce lime is represented below CaCO3 (solid) heat CaO (solid) CO2 (gas) The vertical steel lime kilns have been shown to posses a lot of potentials in the lime industry In view of the need to set up more small/medium scale chemical plans to meet with the local needs of chemical products like lime.

In the second step (Reaction Tank 3), lime is typically used for the precipitation reaction. In this flow diagram, a process known as high density sludge (HDS) is employed to help promote precipitation. The heart of the HDS process is the pH in the HDS or densification tank which needs to be at a pH of 11.5 or higher.

Jul 07, 2017 Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or slight basic BF slag.
Dec 23, 2014 In addition, lime may be used with other materials, such as fluorspar or alumina, to form a synthetic slag, which is used as a flux to remove additional sulphur and phosphorus after the primary steel making process. In the stainless steel making process lime is used in the AOD (argon oxygen decarburization ) process. High calcium and dolomitic lime used in BOF and
SMA Mineral specializes in lime and dolomite products for the steel industry. Modern steel production requires superior quality flux for the best yield and safety in the process.
