Lime Hydrated Quicklime Lump Granular Micronized Made in Iran

1. Introduction to the Supply Chain Department at Sahi Rasa Company

The Supply Chain Department at Sahi Rasa Company has established a specialized capability in the export of lime products from Iran, recognizing the critical role that quicklime and hydrated lime play in some of the world's most essential industries. Lime is not a glamorous commodity, but it is indispensable: without it, steel cannot be refined, water cannot be purified, sugar cannot be clarified, and soil cannot be stabilized. The department understands these dependencies and has built a supply chain designed to deliver lime reliably, consistently, and competitively to clients across the Middle East and Central Asia.

The department's approach to lime is grounded in technical expertise. Quicklime and hydrated lime are not interchangeable; each has distinct chemical and physical properties that make it suitable for specific applications. Quicklime (CaO) is highly reactive and exothermic when combined with water, making it ideal for steelmaking fluxes and soil stabilization. Hydrated lime (Ca(OH)₂) is more stable and easier to handle, making it suitable for water treatment, sugar refining, and construction. The department helps clients select the right form, grade, and particle size for their application.

For clients in Afghanistan, the Kurdistan Region, Iraq, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, and Syria, the Supply Chain Department at Sahi Rasa Company offers a reliable supply of both quicklime and hydrated lime, in forms ranging from large lumps to micronized powder. The department's logistics team manages the complexities of transporting reactive chemicals, ensuring that lime arrives at the client's facility in optimal condition.

2. Product Overview

Lime is a calcium-containing inorganic material derived from limestone (calcium carbonate, CaCO₃) through calcination at high temperatures (900°C–1,200°C). The calcination process drives off carbon dioxide, producing quicklime (CaO). When quicklime is reacted with water (a process called slaking), it forms hydrated lime (Ca(OH)₂). Both forms have distinct properties and applications.

Quicklime (Calcium Oxide, CaO): A white, alkaline, crystalline solid that reacts vigorously with water, releasing significant heat. It is used primarily in steelmaking as a flux to remove impurities (silica, phosphorus, sulfur) from molten iron and steel. It is also used in soil stabilization, where its exothermic reaction dries and strengthens clay soils; in ore processing, where it adjusts pH and precipitates metals; and in flue gas treatment, where it captures sulfur dioxide and other acidic gases.

Hydrated Lime (Calcium Hydroxide, Ca(OH)₂): A white, dry powder produced by adding water to quicklime. It is less reactive and easier to handle than quicklime, making it suitable for a broader range of applications. It is used in water treatment to adjust pH, soften water, and remove impurities; in sugar refining to clarify cane and beet juice; in construction for mortar, plaster, and soil stabilization; in agriculture to neutralize soil acidity; and in chemical manufacturing as a source of calcium and alkalinity.

Iranian lime is produced from high-quality limestone deposits, yielding products with high calcium content and low impurities. The Supply Chain Department at Sahi Rasa Company offers lime in multiple forms: lump, granular, graded, and micronized. Lump lime is used in steelmaking and large-scale water treatment; granular lime is used in soil stabilization and agriculture; micronized lime is used in chemical manufacturing and flue gas treatment.

5. Industries & Factories Using This Product

Iranian lime is used across a wide range of industries, each with specific requirements for form, purity, and reactivity.

Steel and Metallurgy Industry: Steel mills use quicklime as a flux in basic oxygen furnaces and electric arc furnaces to remove impurities such as silica, phosphorus, and sulfur. Lime also helps to protect the refractory lining of the furnace. In the production of stainless steel and specialty alloys, lime is used for slag conditioning and desulfurization. Foundries use lime in molding sands and as a coating for molds and cores.

Water Treatment Industry: Municipal water treatment plants use hydrated lime to adjust pH, soften hard water, and remove impurities through precipitation. Wastewater treatment plants use lime to neutralize acidic waste streams, precipitate heavy metals, and condition sludge. Industrial water treatment facilities use lime for boiler feedwater treatment and cooling water conditioning.

Sugar Industry: Sugar factories use hydrated lime to clarify cane and beet juice. Lime is added to the juice to raise pH and precipitate impurities as insoluble calcium compounds, which are then removed by filtration. This process, known as defecation or carbonation, is essential for producing high-quality white sugar.

Construction Industry: Construction companies use hydrated lime in mortar, plaster, and render for its workability, water retention, and durability. Lime is also used for soil stabilization, where it improves the strength and bearing capacity of clay soils. In road construction, lime is used to stabilize subgrades and base courses. Manufacturers of autoclaved aerated concrete (AAC) use lime as a raw material.

Chemical Industry: Chemical manufacturers use lime as a source of calcium and alkalinity in the production of calcium carbide, calcium hypochlorite, calcium stearate, and other calcium compounds. Lime is also used in the production of citric acid, gluconic acid, and other fermentation products.

Environmental Industry: Lime is used in flue gas desulfurization (FGD) systems to capture sulfur dioxide from power plant and industrial boiler emissions. It is also used in waste incineration plants to neutralize acidic gases and stabilize ash.

Agriculture Industry: Farmers use agricultural lime to neutralize soil acidity and improve nutrient availability. Lime is also used as a calcium supplement in animal feed and as a disinfectant in poultry houses and livestock sheds.

Food and Beverage Industry: Lime is used in the production of corn tortillas (nixtamalization), in the processing of fruits and vegetables, and in the clarification of juices and beverages.

Pharmaceutical Industry: Pharmaceutical manufacturers use lime as a source of calcium in antacids, calcium supplements, and dental products.

The Supply Chain Department at Sahi Rasa Company serves clients in all these industries, providing lime in the form and grade that best suits their needs.

6. Key Properties & Advantages

Iranian lime offers several key properties that make it valuable across diverse applications.

High Calcium Content: With CaO content of ≥ 90% for quicklime and Ca(OH)₂ content of ≥ 92% for hydrated lime, Iranian lime delivers high reactivity and efficiency. This reduces consumption rates and lowers operating costs for industrial users.

Controlled Reactivity: The department offers quicklime with controlled reactivity, ensuring consistent performance in steelmaking and soil stabilization. Hydrated lime is produced with controlled particle size and moisture content for reliable performance in water treatment and sugar refining.

Low Impurities: Iranian lime has low levels of silica, iron, and alumina, which minimizes slag volume in steelmaking and prevents discoloration in sugar refining and chemical manufacturing.

Versatile Forms: Available in lump, granular, and micronized forms, Iranian lime can be tailored to the specific requirements of each application. Lump lime is ideal for steelmaking and large-scale water treatment; granular lime is used in soil stabilization and agriculture; micronized lime is used in flue gas treatment and chemical manufacturing.
