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 consumer end, and the transport service is calculated according to the transport situation of this product in this region. Sulfamic acid is widely used in fields such as the textile industry, the paper industry, agriculture, the petroleum industry, the electroplating industry and cleaners; Sulfamic acid is modelled as a pure substance; when modelling this substance the user needs to add a solvent of their choice in the model; the dataset contains the main raw and auxiliary materials, energy, waste and atmospheric emissions of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include sulfonation reaction, dilution and filtration, dissolution, filtration and collection, crystallisation and centrifugation, and drying, cooling and screening.
Activity Description
The production activities of this product include sulfonation reaction, dilution filtration, dissolution filtration collection, crystallization centrifugation, drying, cooling and screening and other processes.
Process Description
The chemical formula of sulfamic acid is NH2SO3H, CAS number is 5329-14-6. It is an inorganic solid acid formed by replacing the hydroxyl group of sulfate with an amino group. It is generally a white, odorless rhombic flake crystal. The aqueous solution of sulfamic acid has the same strong acidity as hydrochloric acid and sulfuric acid, so it is also called solid sulfuric acid. It is non-volatile, odorless and has low toxicity to the human body. Sulfamic acid is widely used in the textile industry, paper industry, agriculture, petroleum industry, electroplating industry and other fields, and can also be used in cleaning agents.

Technology comment
The urea method is a mainstream mature technology for preparing sulfamic acid. It has strong process stability and occupies a leading market share in the domestic sulfamic acid production field. It is both advanced and industrially representative. This data set represents this mainstream technology: fuming sulfuric acid and urea are added to the sulfonation reactor for reaction, and the temperature is controlled by circulating cooling water to reduce the occurrence of side reactions; the reaction solution is washed with fresh water and sulfuric acid solution and then filtered to obtain a crude product; the crude product is dissolved and filtered, crystallized and centrifuged, and finally dried, cooled and screened to obtain the finished product. The chemical reaction equation involved is mainly: (NH2)2CO + H2SO4 + SO3 → 2NH2SO3H + CO2
