Na₂SO₄ Production Plants
Highlights
Production of high purity Na₂SO₄ from brine:
- Na₂SO₄ ≥ 99.5 %
- H₂O ≤ 0.5 %
- Close granulometry
- Minimal fines
Feedstocks
Na2SO4 brine feed – all concentrations
Process Characteristics
- Utilization of glauber salt route to minimize energy consumption
- Direct conversion of glauber salt to anhydrous in melter
- Crystal size can be selected over a wide range
- Close crystal size with minimum fines
- Low product moisture content of product from fluid bed dryer
Plant Characteristics
- Wide range of feed compositions
- MVR or multiple effect depending on utility costs
- Cooling water requirement minimised by utilization of brine for condensation
- High plant availability
