Reference product: sodium sulfate, anhydrite [kg]
Location: RER - Europe
This dataset represents the co-production of sodium sulfate and hydrochloric acid by means of the Mannheim process.
Sodium sulfate is found in nature in the anhydrous form (thenardite) or the decahydrate form (Glauber's salt). Sodium sulfate is also produced chemically – either as a by-product of other processes or as the main product of a process. Sodium sulfate is used for the production of soap and detergents, textiles, pulp and paper, glass and for a variety of other uses – e.g. carpet fresheners or starch manufacturing.
Hydrogen chloride (HCl) is a colorless to yellowish fuming liquid with a sharp, pungent odor. It is a strong highly corrosive acid. The main applications
for HCl are according to (Inchem hcl):
- Acidizing (activation) of petroleum wells
- Manufacture of dyes, phenols and plastics
- Ore reduction (manganese, radium, vanadium, tantalum, tin and tungsten)
- Food processing (corn, syrup, sodium glutamate)
- Pickling and metal cleaning
- Industrial acidizing
- Water treatment
- Resin regeneration and demineralizers
Due to a lack of industrial data, this dataset is based on literature and stoichiometric calculations.

[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
