Applications
-
Raw Brine Treatment
Brine purification improves the brine quality upstream of a salt crystallisation plant.
-
Vacuum Salt
Mechanical vapour recompression (MVR) technology enables salt producers to benefit from lower operating costs where the relative price of electricity is more attractive than that of steam.
-
Re-Crystallisation
Re-crystallising rock salt or solar salt is a very energy efficient means of producing high quality vacuum salt characterised
-
Calcium Chloride
Complete process chain from the production of CaCl₂ solution, through its concentration, to the final product.
-
Potassium Chloride
Highlights In the potash industry potassium chloride is separated from the KCl containing mother liquor of different compositions depending on raw material in DTB (Draft Tube Baffle) or FC (forced circulation) crystallisers under strictly controlled conditions to produce crystals with a closely defined Crystal Size Distribution.
-
Combined production of NaCl and CaCl₂
Recovery of high purity NaCl and CaCl₂ from waste water discharged from the soda industry.
-
Combined production of NaCl and Na₂SO₄
Producing high quality NaCl and Na₂SO₄ in the same plant offers an attractive means of utilising sulphate rich brines as a feedstock for salt works to maximise revenue
-
Industrial Waste Water
Evaporation of salty process waste waters to recover high quality salt (e.g. NaCl) which can be marketed.
-
Shale Gas-Produced Water
Evaporation of produced water from hydrofracking to recover pure condensate and high quality salt (e.g. NaCl and/or CaCl₂) which can be marketed.
-
Ammonium Sulphate
Crystallization of ammonium sulphate in modern DTB (Draft Tube Baffle) crystallisers under strictly controlled conditions to produce large crystals with a close Crystal Size Distribution.
-
Aluminate Liquor
In the Bayer process for the production of alumina from bauxite ore the weak aluminate liquor has to be concentrated so that it can be recycled to the digestion.
