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 bicarbonate is commonly used in food, pharmaceutical, household and other fields; this dataset includes the main raw and auxiliary materials, energy, air emissions and waste of the production process, and infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; in this dataset, sodium bicarbonate is modeled as a pure substance, and when modeling this substance in solution the user needs to add a solvent of their choice in the model; the data inventory is formed by merging data from multiple sources; the production activity of this product includes feeding, rinsing, mother liquor treatment, drying, pneumatic conveying and other process steps, and ammonium chloride and sodium bicarbonate are co-products of this production process, allocated according to physical relationship

Process Description
Sodium bicarbonate (CAS number 144-55-8) is a white crystalline powder with the chemical formula NaHCO3, commonly known as baking soda. It is stable at ambient temperature but gradually decomposes above 50°C to form sodium carbonate, water, and carbon dioxide. It is readily soluble in water and forms a mildly alkaline solution. Its vigorous reaction with acids releases carbon dioxide, making it a common raw material for leavening agents and fire-extinguishing agents. In the food industry, it is widely used to leaven baked goods such as bread and biscuits. It is also used as an antacid in pharmaceuticals and for household cleaning and deodorizing.
