Description
Ammonium chloride is a white crystalline powder or granule, commonly used as a cleaning agent, and is applied in the agricultural field, in medicine and in the food industry; the dataset includes the main raw and auxiliary materials, energy, atmospheric emissions and wastes of the production process, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; in this dataset, sodium bicarbonate is modelled as a pure substance; when modelling this substance in solution, the user is required to add a solvent of their choice in the model; the data inventory is formed by merging data from multiple sources; the production activities of this product include feeding, rinsing, mother-liquor treatment, drying, pneumatic conveying and other processes. Ammonium chloride is a by-product of this production process, allocated based on the physical relationship.

Process Description
Sodium bicarbonate (chemical formula NaHCO3; CAS number 144-55-8) is typically a white, odorless crystalline powder. It is readily soluble in water, and its aqueous solution is weakly alkaline. On heating, it decomposes to sodium carbonate, carbon dioxide, and water. Sodium bicarbonate is mainly used as a leavening agent and acidity regulator in food processing and is also used in flue-gas treatment, water treatment, pharmaceutical preparations, and the manufacture of other sodium salts and chemical products.
