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. Strontium carbonate is widely used in electronic ceramics, glass, coatings and pigments, metallurgy, chemical and pharmaceutical synthesis, fireworks luminescent agents and other fields; strontium carbonate 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, air emissions and waste of the production process, of which the waste gas treatment process is included within the dataset boundary, and 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 crushing, roasting, leaching, carbonation, pressure filtration, washing, drying and other process steps.
Activity Description
The production activities of this product include crushing, roasting, leaching, carbonization, filter pressing, washing, drying and other processes.
Process Description
The chemical formula of strontium carbonate is SrCO3, CAS number is 1633-05-2. It is usually a white powder or colorless orthorhombic crystal, odorless and tasteless, and has a fine texture. Slightly soluble in water, insoluble in organic solvents such as ethanol and acetone, easily soluble in dilute acid and releasing carbon dioxide gas; chemically stable, not easily decomposed at room temperature, it will decompose into strontium oxide and carbon dioxide when heated to about 1340°C, and can react with quartz sand at high temperatures to form strontium silicate. Industrially, it is mainly used in the field of electronic ceramics (preparing piezoelectric ceramics, thermistor ceramics, etc., for the manufacture of electronic components), the glass industry (as a glass clarifier and colorant, improving the transparency of the glass, and also making strontium glass for optical instruments); also used in the coating and pigment industry (production Anti-rust pigments, white coatings, replacing part of titanium dioxide), metallurgical industry (as a steelmaking desulfurizer to improve the toughness and processing properties of steel), and can also be used to prepare other strontium compounds (such as strontium nitrate, strontium chloride), pharmaceutical intermediates, and as a raw material for red luminescent agents in fireworks manufacturing.

Technology comment
The continuous carbonation method is the advanced mainstream technology for the production of strontium carbonate. It is produced via the process of roasting, leaching, and continuous carbonation of celestite ore. The product has high purity and large production capacity, accounting for over 90% of the domestic strontium carbonate market; the batch carbonation method has been listed for elimination. This data set represents the mainstream technology: celestite is crushed to about 120 mesh, beneficated to remove impurities, mixed with pulverized coal, fed into a roasting furnace, and roasted at 1000-1200°C to reduce strontium sulfate into water-soluble strontium sulfide. Then, the strontium sulfide is leached with water, separated from the insoluble residue, and refined to obtain an aqueous strontium sulfide solution. This solution enters the carbonation tower, where carbon dioxide is introduced to produce strontium carbonate and hydrogen sulfide gas. The strontium carbonate is discharged from the bottom of the tower, then filtered, washed, and dried to obtain the final product. The main chemical reaction equations involved are: SrSO4 + 2C → SrS + 2CO2↑, 2SrS + 2H2O → Sr(HS)2 + Sr(OH)2, Sr(OH)2 + CO2 → SrCO3↓ + H2O, Sr(HS)2 + CO2 + H2O → SrCO3↓ + 2H2S↑, SrS + CO2 + H2O → SrCO3↓ + H2S↑.
