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; the production activity of sodium nitrate powder is mainly "sodium nitrate, neutralization process, powder", and it is also a by-product of the "sodium nitrite, nitrogen oxide alkaline solution absorption process, powder" production process; the production activity of this product is the weighted average of these production processes; if you cannot determine the specific production process of sodium nitrate powder, you can use this dataset, and for the specific technical details, boundary scope and other information descriptions you may refer to the various ethylene production datasets, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary.
