Description
Potassium chloride is widely used in fields such as agriculture, chemicals, pharmaceuticals and food processing; Potassium chloride is modelled as a pure substance; when modelling this substance, the user is required to add a solvent of their choice in the model. The dataset includes the main raw and auxiliary materials, energy, wastes, water-body and atmospheric emissions of the production process, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include decomposition and crystallization, blending, primary roughing, secondary cleaning, washing and filtration, centrifugal drying and other process steps.
Activity Description
The production activities of this product include decomposition and crystallization, blending, primary rough selection, secondary selection, washing and filtration, centrifugal drying and other processes.
Process Description
Potassium chloride has the chemical formula KCl and CAS number 7447-40-7. It typically occurs as colorless cubic crystals or a white crystalline powder. Potassium chloride is a common inorganic salt with a salty taste. It is readily soluble in water, soluble in glycerol, slightly soluble in ethanol, and insoluble in diethyl ether and acetone. It is used as a potassium fertilizer in agriculture to promote crop growth and is also widely used in the chemical, pharmaceutical, and food-processing industries.

Technology comment
Carnallite ore processing is the traditional mainstream technology for industrial-grade potassium chloride production. It is produced through the decomposition, flotation and purification of salt lake carnallite. It accounts for more than 90% of the domestic potassium chloride market and is the core technology of the potash fertilizer industry. This data set represents the mainstream technology: carnallite is dissolved and slurried, and potassium chloride is separated using flotation. The selected potassium chloride is washed and filtered, and finally centrifuged and dried to obtain the finished product.
