Crystallization of sodium sulphate is one of GEA Messo PT
core business. Sodium sulphate, in its anhydrous form and high purity, is used
in the manufacture of detergents, paper, glass and has many chemical
applications.
It is produced from natural minerals like
Mirabilite, Glauberite and Thernadite, or from natural salt lakes.
Secondary sources of sodium sulfate are by-products of
chemical processes where the neutralization of acidous (e.g. H2SO4) or alkaline (e.g.
NaOH) tail solutions produces a sodium sulphate solution. Typical examples
are the regeneration of spin bath liquors, the chromium industry, and the
production of Vitamin C. GEA Messo GmbH has been active in all these fields by
supplying:
- Mineral dissolution
- Brine purification
- Glauberīs salt crystallization
- Calcination of the Glauber’s salt by crystallization of
anhydrous sodium sulphate, including separation and drying
GEA Messo PT has supplied over 70
installations with capacity ranging from 200 kg/h to 40 t/hr of anhydrous
sodium sulphate.
GEA Messo PT
maintains a modern Research Centre in which process designs can be evaluated
and detailed modeling can be carried out, to ensure a successful installation.
