In the chlor-alkali industry waste hydrochloric acid (HCl) is very hard to dispose of due to its harmful environment impact. Calcium chloride can be generated from the neutralization of HCl and limestone to produce a valuable product.
We can offer the complete processing system to produce calcium chloride which comes in the form of flakes, pellets / granules, powders and liquid solutions, each in varying concentrations thanks to our leading position and experience in the field of alkali concentration, flaking and prilling plants. The product is typically available in form of lye or in solid form or as granules.
Calcium Chloride has extensively used for roads de-icing, dust control, brine refrigeration, dehumidification, setting time reduction in concrete, petroleum oil extraction and food processing. The chemical is also useful as a fertilizer for plants, because of its important micronutrients that are vital to healthy plant growth and development.
Calcium chloride is produced as a product solution from reaction of calcium carbonate and hydrochloric acid upon the following reaction:
CaCO3 + 2 HCl = CaCl2 + H2O + CO2
Limestone is used as source of calcium carbonate.
The purification of the product is mainly accomplished by adding Ca(OH)2, in order to remove Magnesium.
The high purity of the produced carbon dioxide makes it suitable for applications within the food and pharmaceutical industries.
