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 consumption end, and the transport service is calculated based on the transport situation of the product in the region. Sodium nitrate is widely used in chemical industry, pharmaceuticals, metallurgy, glass, dyes, agricultural fertilizers and other fields; sodium nitrate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy and air emissions of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes neutralization reaction, evaporation and concentration, cooling crystallization, centrifugal drying and other process steps.
Activity Description
The production activities of this product include neutralization reaction, evaporation concentration, cooling crystallization, centrifugal drying and other processes.
Process Description
The chemical formula of sodium nitrate is NaNO3, with CAS number 7631-99-4. It appears as colorless, transparent or white rhombic crystals with a slight yellow tint. It is non-flammable, has a bitter and salty taste, is easily soluble in water and liquid ammonia, and is slightly soluble in glycerol and ethanol, with a neutral solution. It can support combustion, is oxidizing, and is toxic. Sodium nitrate is an important inorganic chemical raw material, widely used in industries such as chemical, pharmaceutical, metallurgy, glass, and dye, and can also be used as agricultural fertilizer.

Technology comment
The neutralization method is the traditional mainstream technology for the production of powdered sodium nitrate. It is produced through the neutralization reaction of nitric acid and soda ash/caustic soda. The process is simple and low-cost, accounting for more than 85% of the domestic powdered sodium nitrate market. This dataset represents this mainstream technology: nitric acid and sodium carbonate enter the reaction kettle to react, and the resulting sodium nitrate solution is sent to the buffer tank and flows to the evaporator, where the sodium nitrate solution is evaporated and concentrated; the concentrated liquid is transported to the crystallization tank for natural cooling and crystallization, and then a centrifuge is used for further centrifugation and dehydration to obtain the finished sodium nitrate product. The main chemical reaction equation involved is: 2HNO3 + Na2CO3 → 2NaNO3 + H2O + CO2.
