Brine purification improves the brine quality upstream of a salt crystallisation plant.
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-crystallising rock salt or solar salt is a very energy efficient means of producing high quality vacuum salt characterised
Concentration of depleted brine from typically 190 g/l to 310 g/l
Complete process chain from the production of CaCl₂ solution, through its concentration, to the final product.
Production of high purity Na₂SO₄
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.
Recovery of high purity NaCl and CaCl₂ from waste water discharged from the soda industry.
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
Evaporation of salty process waste waters to recover high quality salt (e.g. NaCl) which can be marketed.
Evaporation of produced water from hydrofracking to recover pure condensate and high quality salt (e.g. NaCl and/or CaCl₂) which can be marketed.
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.
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.
