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. Argon can be used as a protective gas widely in fields such as metal welding, semiconductor manufacture and bulb filling, as well as for cryogenic refrigeration, gas chromatography analysis and as an inert environment carrier; Argon 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 air filtration, compression, cooling, purification and fractionation. Nitrogen and argon are by-products of this production process, allocated according to economic value.
Activity Description
The production activities of this product include air filtration, compression, cooling, purification, fractionation and other processes.
Process Description
The chemical formula of argon is Ar, CAS number 7440-37-1. It is a colorless, odorless and tasteless inert gas under normal temperature and pressure. Its liquid form is a colorless and transparent liquid. The boiling point under standard atmospheric pressure is -185.9°C, the critical temperature is 150.8K, and the density is about 1.40g/cm3 (at -185.9°C). It is extremely difficult to dissolve in water and is much denser than air. It is the most abundant rare gas in the air. It is extremely inactive in chemical properties and generally does not react chemically with other substances. It can only form a few compounds under special conditions. It is mainly used as protective gas in industry, such as metal welding, semiconductor manufacturing, and light bulb filling; it is also used in low-temperature refrigeration, gas chromatography analysis, and can be used as an inert environmental carrier in scientific research fields.

Technology comment
Cryogenic air separation is the absolute mainstream technology for large-scale production of liquid industrial gases (oxygen, nitrogen, argon, etc.). It has high technological maturity and stable product purity. It accounts for more than 95% of the domestic liquid industrial gas market and is the core technology path for industrial gas supply. This data set represents this mainstream technology: the air enters the compressor after being filtered, is then cooled by the pre-cooling system, and then passes through the purification system and enters the fractionation tower to obtain liquid oxygen, liquid nitrogen and liquid argon respectively.
