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 an important chemical raw material, widely used in chemical industry, pharmaceuticals, metallurgy, glass, dyes, agricultural fertilizers and other fields; sodium nitrate is modeled as a pure sodium nitrate 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, waste 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; sodium nitrate powder is formed into sodium nitrate pellets through feeding, melting, filtration, granulation, cooling and other steps.
Activity Description
This production activity is the granulation of sodium nitrate powder, which goes through feeding, melting, filtration, granulation, cooling and other processes to form sodium nitrate particles.
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 granulation process is a subsequent molding technology for powdered sodium nitrate. It relies on spray granulation or extrusion granulation equipment to achieve granulation. As a customized product technology, it accounts for more than 70% of the granular sodium nitrate market segment, primarily meeting the demand for granules in fields such as fertilizers and metallurgy. This dataset represents this mainstream technology: sodium nitrate powder enters the melting kettle through a feeder and is melted at high temperature, then solid impurities are removed in the filter; the molten sodium nitrate is formed into droplets by the granulation nozzle and dispersion device, and uniform sodium nitrate particles are obtained after cooling and solidification.
