Sugar Refining |
 |
|
| Lime as a basic industrial chemical finds usage in many other chemical processes. We offer clients superior grade of hydrated lime and other lime chemicals. It is also known as calcium hydroxide and forms an essential part in the production of sugarcane & sugar beets.
Usage:
• It is used to purify sugar from other sources such as maple or sorghum
Process:
• Sugarcane & sugar beets are harvested and processed with water to form raw juice having low PH and containing dissolved impurities
• Hydrated lime is added to juice for raising the PH level and to react with present impurities to form insoluble calcium organic compounds which can be removed
• Excess lime present is removed by carbonation process or by addition of Phosphoric acid
• The whole process is repeated several times depending on purity of final product needed |

Food Industry |
|
|
Lime serves a myraid of uses in the food industry.
1) Dairy Industry- When cream is separated from whole milk. lime water is often added to the cream to reduce acidity prior to pateurisation when butter is produced. Skimmed milk is next acidified to separate casein. the caseine is mixed with lime and a small amount of sodium floride to produce calcium caseinate,a form of glue.
2) Glue & Gelatin- Waste maerial from rendering plants are treated with lime in slurry form. This process swells the collagen, thereby facilitating subsequent hydrolysis.After the treated stock is washed to remove lime,albumin, and mucin. the washed stock is dried and the final product is solid as glue or gelatin.
3) Baking Industry- In the preparation of a common typpe of baking powder,mono calcium phosphate is required as an ingredient.
4) Fruit and Vegetables- Bags of hydrated liem are placed on racks in the storage room to absorb co2 that execudes from the ripening fresh produce. | |

Paper Industry |
|
|
| Lime is traditionally used to reconstitute caustic soda from the sodium carbonate left over from the pulp-making process.
We also supplies high-purity lime for the fabrication of PCC (Precipitated Calcium Carbonate) which is manufactured via a series of controlled chemical reactions. Quicklime is usually mixed with water to form a slurry to which carbon dioxide is added. The resulting reaction produces a very fine precipitated calcium carbonate (CaCO3). This filler is used in paper production to enhance the paper's whiteness, opacity and texture.
Lime is also used as a reagent to soften process water in paper factories. |

Glass Industry |
|
|
we supply the glass industry with extremely pure dolomite of very constant chemical composition and particle size.
Dolomite is mainly used in the float glass industry. This source of magnesium acts as a stabilizer to improve the general resistance of glass to natural or chemical attack.
we also supplies special reagents for industrial flue-gas treatment. | |

Refractories |
|
|
| Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns.
In the steel refining process, the use of dolime instead of pure quicklime will extend the life of refractory linings. In fact, adding dolime will create MgO in solution in the slag, which provides an excellent buffering capacity as MgO particles in suspension provide excellent coating protection. Any excess MgO precipitates, protecting refractories and tap holes, reducing the need for gunning and repairs. |
