Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. Calcium chloride is mainly used as a road snow-melting agent, industrial desiccant, concrete additive and raw material for food-grade products; the dataset models calcium chloride as a pure substance, and when modelling this substance the user needs to add a solvent of their choice in the model; the dataset contains the main raw and auxiliary materials, energy, atmospheric emissions and waste of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings 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 neutralisation and filter pressing, drying, and tail gas treatment.
Activity Description
The production activities of this product include neutralization, filter pressing, drying, exhaust gas treatment and other processes.
Process Description
Calcium chloride (CAS No.: 10043-52-4) is a white crystalline, granular or massive inorganic compound with the chemical formula CaCl2. It is extremely hygroscopic and will quickly absorb moisture and deliquesce when exposed to the air. It is easily soluble in water and releases a lot of heat, and the aqueous solution is neutral to slightly alkaline. As an efficient desiccant and antifreeze, calcium chloride is widely used in road de-icing, coal mine dust control and other scenarios; in the food industry, it is used as a coagulant in tofu making, or as an electrolyte supplement added to sports drinks; its hygroscopic properties also make it an ideal moisture-proof material for container transportation and precision instrument storage. In the chemical industry, calcium chloride is an important raw material for the preparation of other calcium salts and is also used as a drilling fluid additive in oil exploration.

Technology comment
After the neutralization reaction between hydrochloric acid and limestone, it enters the neutralization mixing tank, adds calcium hydroxide to adjust the pH value, and then enters the clarifier for treatment, and then is sent to a filter press to obtain a calcium chloride solution. The reaction formula is CaCO3+2HCl=CaCl2+CO2+H2O; the calcium chloride solution passes through the granulation and drying sections to obtain the product.
